On 12/28/15 I went to an emergency care facility with tingling, itching, red, bruised, knots and semi blistered .places on my leg, arm, and thigh all on the right side. I thought that it could be shingles since I had it before. I was told it did not appear to be shingles but I was given a shot and Vala cyclonic and Gaba pent in to take to see if it would clear up. Two more appeared and later cleared up. Today I have another on my right leg. It itches, has knots, I have a headache and diarrhea. The others have left scars. What could this be?
