I just got out of shower and my heart rate is 120 per min at rest I took all my meds before I got in if the water to hot can you have symptoms?

Go lie down NOW. Not sure how much time passed since you posted. Go lie down, hydrate aggressively & call friend to monitor you. Recheck your pulse a few minutes after. A hot shower will cause vasodilatation and drop your pressure enough to increase your pulse if you are already prone to it, which may be the case if you're taking midodrine & pyridostigmine for POTS. Call doc if pulse doesn't normalize quickly. Read more...
