POTSius

I started exercising on a recumbent bike and then progressed from there I highly recommend it. If like many with POTS you have exercise intolerance of some kind, just do as much as you can to start and advance as you can handle from there I started at just 2 minutes at a very slow speed and eventually worked up to 45m cardio on it and then moved to the upright bike and finally the treadmill, roughly following CHOPs modified Dallas Protocol

The 2nd half of this video discusses salt and POTS, an interesting watch It discusses the importance of salt and I think it touches on your question (can't remember, saw it a few weeks ago) Done by Dr. Satish Raj for the Dysautonomia International conference in 2018 https://vimeo.com/283559045

MCAS symptoms can be similar to allergies. My point was that if you (or the original poster) were having odd symptoms caused by food beyond what normal allergies would entail I think that could be a point in favor of MCAS. To diagnose MCAS, you really need an expert's opinion as they have to take into account symptoms, symptom history, test results, and the overall "picture" of the patient. There is a lot of info online, which can be helpful although it is of varying quality

If it is triggered by food and leads to symptoms that are not typical for an allergic response, MCAS does seem like something to explore. I have MCAS and am intolerant of many foods. Oral cromolyn (Gastrocrom) has helped this and other symptoms. It is also possible the issue is due to something in the food, but in a non immune way. I think some people can have trouble with amines in food, sulfur, salicylates, etc and all of these could cause non allergic responses to food. Maybe there is a pattern in your problem foods?

It could be that the levels of clonidine in your blood are too variable with this dosing. They will be at a peak after taking and then get lower later. Perhaps you feel worse as you are going into a mini withdrawal? Whatever the reason, the clonidine pill for me would work great a few hours and then I would feel worse I solved this by moving to the patch which has worked great as it provides a much more stable dose. I don't take it for sleep so I can't speak for that. I would also note that I actually had worse orthostatic intolerance for a few weeks when starting clonidine until my body adjusted to it, so keep that in mind.

Have you tried other brands of the same class of medicine, maybe you are having an issue with some filler in the medicine? Also a lot of people with POTS (myself included) seem to benefit from starting at a very low dose and gradually increasing the dose as tolerated. Starting with a "normal" dose may be too much.

It may be static electricity. See this link for info on that and other issues. https://us.humankinetics.com/blogs/excerpt/technical-difficulties-in-heart-rate-monitors-may-cause-irregular-numbers I agree with toomanyproblems, if you want to be sure you should measure your pulse manually

At one point the article above mentions that: "In addition, the adrenergic hyperactivation connected with intense emotions and anxiety can, in itself, predispose the patient to supraventricular and/or ventricular arrhythmias" I think this implies that hyperadrenergic POTS could cause the same arrhythmias (for reasons outside of "intense emotions and anxiety") due to the excess adrenergic activity I guess I wonder whether if you tricked yourself into ignoring the palpitations stuff would still be going on behind the scenes that could manifest itself in further, different symptoms

Thank you all for the suggestions Diltiazem sounds interesting This is a very thorough article about that https://academic.oup.com/europace/article/13/7/920/447426 It suggests that the heart can be completely normal and we can still perceive it to be doing something wrong. Maybe our cardiac nerves are somehow sensitized I am not sure if trying to ignore it is a good idea though, even if the heart is not doing anything abnormal

Has anyone found anything especially helpful for heart palpitations? Mine are triggered by exertion and feel like an excessive pounding of the heart (but heart rate and pressure seem normal, although I am on a beta blocker so I wonder if my heart rate would be elevated otherwise) I have found ivabradine to sort of help but that is about it

Maybe the patch would work I am diagnosed with hyperadrenergic POTS and MCAS Have you had a tilt table test? I think hyperadrenergic POTS is usually diagnosed based on symptoms + a positive tilt test + a rise in nor-epinephrine levels

I get this. I also get a similar thing on my hands and my feet It has gotten better though as I have got my hyper POTS/MCAS more under control It seems similar to erythromelalgia but without the pain I notice that heat is a big trigger for it

Did you try the patch or the pills? For me the pills were not great, I would first feel very good and energetic and then burn out/have the meds wear off and feel awful. I think it is because the pills do not provide a very stable level of the medicine in your blood. But the patch worked great Are your symptoms triggered by certain things? It took me a while to realize that certain types of TV, music, watching sports etc were actually causing problems. Maybe some of these things are excessively activating your sympathetic nervous system and leading to issues

Have you tried clonidine?

I had moderate acid reflux and what helped me was a combination of pepcid and baking soda The pepcid only did about 60% of the job and the baking soda did the rest I take the pepcid in 3 doses throughout the day, seems to work best that way I take about 1/4 tsp baking soda mixed in water maybe 6-7 times spread throughout the day the baking soda is also very useful for managing when the reflux happens in the middle of the night, super quick relief If you try it, you have to be careful not to take it too close to a meal (I typically wait about an hour) as someone once died from that (I think that is a super rare thing to happen though). I would ask your dr if you are concerned about that.

I have MCAS and allergies definitely seem to worsen it for me I imagine the allergies ramp up the immune system in a way that makes the MCAS worse Or maybe MCAS predisposes you to more serious allergies and more unusual responses to them

Be careful in testing to know there is a difference between mastocytosis, MCAS and MCAD (Some Dr.s hear MCAS and think mastocytosis, a different disorder) As a word of caution, MCAS is a relatively recently described disorder, so I do not think all allergists will know how to test for it or even know what it is You will want to make sure you find a dr. who knows/has experience with MCAS or is willing to contact an expert to learn how to properly test for it

I think you are wise to avoid the steroids if you can I have MCAS and from what I understand H1 and H2 antihistamines are typically one of the most important parts of a MCAS treatment regimen, so maybe talk to your dr. about trying those? Even if you have tried claritin already, at higher doses perhaps it will help

That it occurs in fall suggests it could be related to some environmental trigger (like ragweed) Have you explored allergies or mast cell activation syndrome as causes?

I also had bad headaches in my temples Have you tried self massage? I made a post a few weeks ago describing what I do (linked below) I think that if you try lightly massaging that area, and can find any sore/tender spots then that would be a good sign that the massaging might help Headaches were one of my biggest problems for years so it was amazing when I figured this out

Do you have any allergy or mast cell type issues?

In hyperadrenergic POTS, there is excessive sympathetic nervous system activity A beta blocker is only blocking the beta receptor mediated effects of excess sympathetic nervous system activity There are also alpha receptors which respond to adrenaline and noradrenaline and which could be mediating symptoms In addition, the sympathetic nervous system releases things called co-transmitters like NPY, and purines (like adenosine, ADP, ATP, this is called purinergic signalling) that can have additional effects So I think it makes perfect sense that a beta blocker would not block all the effects of excessive sympathetic nervous system activity I personally have found that even though I am on a beta blocker and it is controlling my heart rate I still have orthostatic intolerance (just not tachycardia while the beta blocker is working)

Maybe an E-ink screen would help? Or a program like flux that controls screen color temperature? For boredom, I find it helps to space out activity throughout the day vs using all of my energy at once and then not being able to do anything later That way you only have to deal with shorter periods of boredom and can always look forward to the activity which will never be too far away

Lots of topics seem to be about a flare up in symptoms right now I experience regular flares in my symptoms each fall and I was interested in others experiences Especially whether this phenomena is limited to those who also have allergy/mast cell issues Or whether this affects those with dysautonomia more broadly, for some other reason (light changes?)

Benadryl (US version, i.e. diphenhydramine) is my go to for when I am not able to fall asleep But in my case, this may be due to it helping with MCAS vs POTS Although I think it tends to help people fall asleep in general as well
