Every so often I get these itchy (sometimes painful also) rashes over most of my body. It can be slightly different areas but usually involve at least parts of my torso, arms, legs, and face. It gets warm and usually red.
The worst part besides the itching is this tingling flushing sensation that sort of washes over the affected areas, usually repeatedly. It's like the feeling of my leg falling asleep for a short while and is just waking up over and over again. The flushing isn't painful but it is annoying and distracting; a continual rush of sensation.
I've been taking antihistamines for years and sometimes use hydricortisone cream. It can also help to keep the affected areas really cold to cut down on the itching, heat, and tingling. But sometimes the syptoms are too much and I'll continuously feel the heat, tingling flush, and itching regardless. It always lasts for weeks at a time. Sometimes, the rash on my fingers and toes get really red, swollen, and inflamed so that I can't even bend the joints. And when the swelling does go down, the redness can stay for a long time. When I'm bathing the red color starts to look grayish or purplish like fading bruises.
The rashes themselves (before any swelling) tend to show up as small pustules or red round bumps that come in curved arc patterns. If it's pustules, then they start clear and turn yellow before eventually disappearing.
I tend to get it bad every few months and then it lasts for weeks at a time.
