Okay, idk how to explain this but my boyfriends arm is hotter than the other?

Question

He also complains of right knee pain.

And his arm(the top of his arm not the bottom) from his elbow to his wrist is red and hot to the touch, it also feels hot to him... but doesnt hurt?

But his left arm is perfectly fine?

He doesnt have any bug bites or anything?

What could be casuing this?

P.S. DO NOT answer if ALL you have to say is go to the doctor.

And he didnt rub it on anything or scratch it or anything like that. We just got back from walking about an hour ago and now this is happening.

Answer 1

it sounds like it is most likley related to blood flow. feel his pulse points at the wrist,inner elbow and at the ankle. you will probably find that either you can't locate it on the right side or that it is weaker. the fact that it's worse after exersise also indicates blood flow problems. I don't know how old he is but i wouldn't ignore it. Is he a smoker? there is also something called rynards syndrome that sounds similar, but usually it affects extremities and they get numb, so i don,t know? any way i won't say it but pay attention. good luck
