Are you dealing with anxiety as well? Have you been to a psychologist to assist with the anxiety? Some believe this condition is caused by anxiety or similar things- a physical condition brought on by the mental stress. I’d try that route if you if haven’t.
I also suffer from Morgellons disease. I have had it for about 2 1/2 years now. It was ground breaking when the Strickler research papers came out last year. I finally understood that I had late disseminated Lyne, and other coinfecctions. I also got lab results showing I have funnelformis mosseae. I started seeing a LLMD ( Lyme litterate MD. I could not find a physician to treat me in Florida. I did see an alternative doctor in Orlando, but felt he was only after money. I now have to go all the way to D.C. to see my doctor, but I am slowly improving. The best thing to do in my case was to that the underlying infections. I can tell you that the sores are difficult to treat. I have had some success using tinactin to dry them up, and Epson salt concoctions can help get rid of toxins. It is a really hard disease to deal with, and so little us know at this point. I wish you success!
