<s>[INST] For the last three to four months I have had a blistery rash appear on my righ hand. It is mainly on the fingers, very hot and itchery. The bliters come up and then ooze. After about 48 hours the skin breaks down and drys out and is very sensitive to touch. The dry skin then peels off over the next couple od days. This issue seems to repeat every 3 - 4 weeks [/INST] Hi, The rashes since occurring on the exposed part may be due to allergic response or due to any infection or infestation. Allergic reaction, scabies or even any infections like fungal or bacterial can cause this type of presentation. It is better if you can upload a high quality photo of it which will help us in better diagnosis. For now, you can take antihistamine Chat Doctor.  This will help in preventing the symptoms for now.
