I have several areas on my leg, ankle, shin that are extremely red, painful blisters that ooze yellowish fluid, sometimes chills, fever never higher than 100.4, night sweats. Blood work, biopsies, culture tests for fungus, bacteria, viral all have come back negative. This started in August, thought at first cellulitis, but antibiotics did not help. My body seems to be healing itself, most areas are drying up and my energy and appetite are back. Lost 15 pounds. My fear is that since we cannot identify it , it will come back again.
