Suggest remedy for rashes
Patient: I have what appears to be a rash on both my shins.  There are blotchy areas consisting of tiny red dots, they range in size from a pencil eraser to about 2 x 1 inches.  They do not itch, they are not raised, have no borders, they are not dry or scaly and only appear on the front and sides of my lower legs.  I first noticed one spot the size of a pencil eraser near my ankle about a month ago and a few days later they are all over my shins.  I thought maybe it could have been from shaving with a disposable razor but it has not improved with using a brand new razor each time.  My diet, detergent, lotions, soaps have not changed.  What could this unusual rash be? Doctor: Hi,  It seems to be vasculitis or pigmented purpuric dermatoses. I would recommend you to consult a doctor and get it examined.  Take care. Hope I have answered your question. Let me know if I can assist you further.  Regards, Dr. Asmeet Kaur Sawhney, Dermatologist
