I’m 19 years old, and I have been experiencing the symptoms described on cholinergic urticaria. I have intense, slightly painful itch on the inside of the skin, almost as if in the veins, which if I scratch it gets really worse, with temperature rise or while in hot showers or washing my hands, sometimes simply by lowering my arms outside the bed if im laying down (focusing the blood circulation on my hands/arms).
However, the thing is I only feel it on the palm of my hands. I don’t feel it anywhere else, and I have no visible rash or hives. Sometimes I have a bit of swelling of the hands and some slight redness.
I have been experiencing this for the last four years, and my doctor said it might be only a heat allergy, which I searched online and doesn’t match my symptoms. Also, my blood test had no issues.
Please help me. It sucks not knowing what I have.
