<s>[INST] Hello, I have a strange rash on my ankle. It s on the side around my scar and part of the top of my foot. I have nerve damage from a fall. They did surgery that did not help. Now they are trying a thing where they try and shock the nerves. I had a second treatment 2 weeks ago. The rash does not itch, but the skin feels tight. The rash is red and looks like either broken blood vessels or small blisters. It s Friday night so it s to last to see the doctor. Any ideas? [/INST] Hi, It may be Chambers disease. It is considered as capillaries. The Ra's is due to hemosiderin pigments in dermis caused by rupture of capillaries after leaking the blood in the dermis.  Consult the dermatologist for the perfect diagnosis and proper treatment. Take tab vitamin C 1000 mg daily for a long time. Keep the foot elevated while sleeping. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
