I think I might be the only person in the world who doesn't get sleepy from benadryl. I'm not always sure that's a good thing! :D

.

benedryl doesnt make me sleepy either .. but i think its becuase i have taken antihistamines most of my life so they dont have the same affect they once did

This would happen to me all the time. Especially when I would start working out.


Here could be another reason for the cause, in case Benydril doesnt work.

"Itchy skin usually occurs during exercise performed after a long period of inactivity. The itching is not on the skin, it's inside the actual limbs. There are millions of tiny capillaries and arteries inside our muscles which expand rapidly due to the demand for more blood that is brought on by exercise. When fit, these capillaries remain open allowing maximum blood passage, but when unfit and inactive they tend to collapse, allowing only minimal blood passage (which is sufficient for a sedentary person however). The rapid expansion of these vessels causes adjacent nerves to send impulses back to the brain which are interpreted as an itch. That's why after a few sessions the sensation tends to go away. Just another indication of increasing fitness levels."

nah its got to be histamine for me i have been working out almost everyday for 6 months.. its only been the last week.. and its been cold here so.. im sure that is it..

I too experienced this when I first started working out. I always thought it was due to increased blood flow... Not allergies or histamines... It doesn't happen any more now... except if it's really cold.

Keep up the good work!

It was terrible when I first started exercising. Crazy mad itchies. Now that I exercise regularly it hasn't happened in awhile... or I don't notice it anymore.

I'm with you. Mine had to be a vascular thing. (Either that or the constant jiggling!) Never happens anymore though. (oh yeah, the jigging does!)

Amy - it is wintertime there in Australia right? Is it dry?

I'm never itchy on my arms or legs, it's always on my belly and my sides....esp. when I'm trying to run. Then once I start itching, it seems to last forever

Hmmm, I thought it was my lotion and deoderant reacting with the extra body heat and sweat because it was really unbearable at "creases" like my underarms and backs of my knees. Now I shower before I work out and don't put anything on my skin (out of consideration for others, I work out at home :lol: ) and haven't any more problems with being itchy (but DH is getting testy about the water bill).
