Hi. I'm Female, 51 Yo, And Have Had Chronic Lyme

Hi. I'm female, 51 yo, and have had chronic Lyme disease for many years. For the past few months my shins have had itchy sores on them. I thought the first one was a ringworm. I treated it with fungicide cream and it went away. But there are more spots now that look like clusters of rash(es). Mostly they itch, but they also just look terrible. I use lotion daily so I don't think it's a dry skin issue. The itching started when I was on antibiotics for Lyme--had been on antibiotics for 18 months with drugs changing every 8 weeks or so, sometimes IV, sometimes oral, sometimes both. But, I have been off antibiotics for about 3 weeks now, and I have been using the fungicide all over these sores but it hasn't helped. Any ideas would be appreciated. Thank you, Sandra
