Itching/pins And Needles When About To Sweat


Recommended Posts

Hi everyone, I have had a bizarre problem for the past couple months. Whenever I walk around outside and get to the point that I would usually sweat, I get a pin prick sensation on my arms and torso. When I scratch my arms during these episodes, it leaves red lines. If I were to scratch my arms right now, sitting inside, there are no red marks. The sensations go away if I either go inside and cool down, or continue to heat up further and fully begin to sweat. Claritin has had no effect, and it seems like I do eventually sweat in the areas where the pins and need pain is coming from. Does this sound histamine based, or autonomic function based? I am considering spraying some benadryl cream on my arms and seeing if that helps to determine whether this allergy based. I don't get the sensations at all after taking a hot shower, or getting hot indoors. I also did not notice this over the fall or winter.

Thanks

This happens to me when my skin is dry, which happens all the time... because I have dry skin. So, when I start working out my scalp will itch and skin, but then it gets better in a few minutes. It helps to not itch.

I've had that now for a few years. It is so intense that I literally cannot be in temps over 80F for more than about 5-10 minutes. I quit sweating to heat for some reason, and now that's what happens. When I get warm, my body has a hot flush and that just makes it all so much worse. The itching begins on my back and then travels upward. I have had bad poison ivy a few times in my life, and this is so much worse! It is like there are ants all over me, biting, but not hurting, just itching.

What's strange though, is this only happens when I get hot outside, which is making me lean towards histamine problems. I could get in a sauna and get super hot and not have this terrible pins and needs sensation, but if I walk briskly outside for several minutes, I feel like I am being attacked by fire ants.

Hi, gofl1.

I'm so sorry you're experiencing this, as I know how very miserable it is, and limiting! but I'm glad you posted this here. I started this last year, and I do the exact same thing! I used to be able to sit outside, in the heat, all day long, with no problem. Now, I can't be out for more than a few minutes during a hot day, or it drives me up a wall with all the itching and tingling I start to do, then the weird kind of sweating that comes--it feels funny when I do then start to sweat. And, yes, when I scratch, I'll get scratch marks right away. But, I, too, can take a hot shower and not experience this. I take three antihistamines every day and am on corticosteroids, and I still do this, so I don't know about histamine being the culprit or not, either.

I started Singulair the winter prior to this starting, so I wondered if it, or even the Pepcid or Allegra, was the cause. I also wondered about my elemental formula, as it's filled with artificial sweetener, if that could be causing it.

Last spring was the first time in my life I ever got sun poisoning, too. I got it on my lower legs. I didn't know what it was and was scared. My husband called my doctor's office and described it, and they explained what it was. I had to put ice on my legs several times a day to soothe and heal it.

If you hear what this is, please keep us posted. I'd love to know why I'm doing this now, after 46 years of being a sun flower!

Well, it was 80 degrees today, humid, and within minutes, I had the uncomfortable feeling, itchy sweating, etc. I am so disappointed. I had to come inside while my husband worked our gardens. I am not looking forward to another summer this way. If anyone knows what this is, please let us know.

Thank you.

Linda

I have this issue too! I haven't been diagnosed with anything - my doctor says its just stress, but I know it's definitely linked to heat.  Does anyone who also suffer from the itchies have any tips on how to get through it in the moment if you can't go somewhere cool? Also, does anyone else notice involuntary leg twitches or shudders when it's really bad?

This could be dehydratiom from Secondary Polycythemia. It happens when your bones put out too many blood cells and your blood thickens. Polycythemia Vera is NOT what I'm suggesting, which is blood disease. I'm suggesting the secondary kind. Before you go outside, try drinking a lot of water. A tall glass. Then test the theory and see if it still happens. It can also possibly be from not getting enough oxygen. I'm a chronic heavy smoker and the pin pricks came on last summer in my legs in August and then stopped after like a week. It's now June the following year and its started again. I've wondered if its hormonal. Ladies... consider this if you have other symptoms going on as well. I'm going to the neurologist tomorrow. I'm terrified that he will say I need to get further testing because I HATE anything medical related, and get severe panic in any doctors offices or if I have to get any testing other than bloodwork. I naturally have nasty panic so it could also be anxiety. Doctors are creeps in my experience. They always hear that I smoke and have anxiety, and want to pin every single ailment on smoking or anxiety, so they don't take me seriously. I end up suffering and never getting a proper diagnosis. Again, try a lot of water because if you're dehydrated, you won't always know it and they'll have you going in for all kinds of tests before finally telling you to drink more. I know this because at one point, I tricked a blood test. They made me think I had one thing because my levels were off and wanted to retest my blood. I downed a bottle of water on the way to the doctor, and results then came back perfect. Instead of warning me of dehydration initially, they immediately blamed smoking and anxiety. You have up so your own research and be your own doctor these days or they'll have you paranoid.
