My hands are blistered and itchy. Touching the affected area is too hot and itchy.

Consider your condition eczema. Can self-heal, method:

In areas with eczema, small areas, you can use this needle, triangular needle, dense needling once and then cupping. It is best to pull out the poisonous blood and give the local area a chance to metabolize. Every puncture, bloodletting and cupping is a small stimulus to the affected area. Cupping can be done several times until there is no toxic blood flowing out. Some people may not bleed after the first puncture. This is local eczema, or the surface of dermatitis is too thick. Maybe the pricking needle hasn't touched the dermis yet. At this time, the dead skin won't bleed. If yes, please buy a large triangular needle and get ready for puncture and bloodletting. Even a few drops of blood will have a trace of blood supply in the dermis. If the amount of bleeding for the first time is not large, or continue to puncture and bleed the next day until the subcutaneous pain is felt during bloodletting, and after each puncture. Each jar contains at least 10-20 ml of blood, which can be punctured every week or several days. Remember, cupping must be done after pricking blood, so that there can be enough pressure bleeding. Then you'd better smoke moxibustion here with a better moxa stick. You know, there's already been a puncture wound here. A good moxa stick can accelerate the entry of vitality, accelerate the repair of skin lesions and accelerate the recovery of eczema. If the area of eczema is very large, it is difficult for us to treat it at one time, so remember, we must treat it in stages and batches. For a large area of eczema, besides pricking collaterals and bleeding, moxibustion should also be applied to Shu Fei, Shu Ge, Quchi, Xue Hai and Hegu to help the whole body adjust.
