Itchy skin when embarrassed or hot
Im 18 years old and for about the last 2 or 3 weeks my skin has become really itchy when I become embarrassed or when I get hot (such as if I start exercising or just if I go into a stuffy place).
The itch is not just one of them itches that feel a bit irritating until you itch, but its actually painful, it feels like there's needles poking at me. I get red patches where the itches occur, which is normally on my chest, back, arms and sometimes forehead and the side of my face, but that is the only reaction that happens (like I don't get a shortness of breath when it happens etc.)
I went to my doctor and he said It was an alergic reaction and gave me anti histamines but they seem to be having no effect as its still happening on a daily basis, I'm going to visit him again but I was just wondering if anyone else has had this before, and knows what it is or how to stop it.
And another thing to point out is that I've been on antibiotics (tetracycline) for about a year and a half now with no breaks.
Really want this problem solved or I fear it will make life when I start university next year very difficult, thanks for all your help in advance.
