Is there a connection between adrenaline and lactic acid?

If I'm not mistaken, lactic acid is the burn you feel when exercising. I've been feeling this burn for over 24 hours in my arms and legs since I fixed one of our bed frames yesterday. It feels like I'm constantly exercising. My pupils are dilated so I know my adrenaline is flowing and I feel so bad I'm about to take pills to make me sleep because I'm suffering. I was wondering if there is a connection between adrenaline and lactic acid.

Physiological stress increases the rate of lactic acid produced by cells. It's likely that people with POTS have chronically elevated lactate. People with POTS often have reduced oxygen uptake by muscles, leading to exercise intolerance. The lack of oxygen causes the muscles to produce lactate from glucose - you've probably experienced this from exercise, especially high repetition weight training. I noticed that when I became sick with POTS that I would more easily get the 'burning' feeling from even mild exercise, such as a fast pace up a flight of stairs.

I mentioned this to my specialist back in February. She didn't even really comment on it. But it's happening any time I do much of anything. I still feel it in my legs. Not as extreme but it's there. And I don't mean my legs are sore I mean they are burning as if your stomach would while doing 50 situps. My job required me to walk all day. No sitting. 8-12 hours. So I was definitely in walking shape but ever since the collapse at work back in September, I've been experiencing all these weird extra symptoms and my body just broke down since then. Just trying to find answers to put me on the path to a better quality of life.

Thanks for the information.

@Derek1987 - I am not sure if this is what you are referring to but I often get burny, heavy, almost "tired" legs when I am too active. That is usually my clue to stop. 

It's the same burn u feel when u do any exercise long enough and u start to "feel the burn".  At times it's made me feel like woah I gotta sit down asap before I collapse (non fainting). It's been 48 hours and my legs are still burning as if I'm working out.

Tenacity - Do you think autoimmune channelopathies could cause this physiological stress leading to low oxygen in muscles -  chronic lactic acid buildup / chronic muscle pain?

It's likely that all diseases feature some level of physiological stress. The lack of blood reaching the brain and heart in POTS is enough to stress the cells there. One study found that POTS patients had higher cortisol levels than controls, and cortisol is a marker of physiological stress.

I don't know what the role of lactic acid is in your question but the long held theory that the reason your muscles felt sore after too much exercise was because of lactic acid build up has been proven wrong. Apparently they now think that is due to micro tears in the muscle. This actually stimulates building of more muscle not scar tissue.

I think some people have a misunderstanding of what I'm saying. I could be wrong but I thought the burn you feel when exercising is lactic acid. I'm not talking about muscles being sore. I'm talking about the burn you feel when you are working a muscle out. My legs/arms were burning for 2-3 days straight as If I were right in the middle of a exercise. Not sore. And it was brought on by a minor task or what use to be a minor task to me. I was just fixing a couple pieces on a bed frame. I felt sick throughout because I was doing it. Then the burning came on and lasted a long time. This happens whenever I do anything almost. Sometimes it comes in waves of intensity. As if you are in the middle of doing situps and can't do anymore because the burn is so strong and my legs feel like giving out.
