I have had cactus thorns under my skin in my hands for almost 2 yrs now. I ve been to primary dr., dermatologist, infectious disease dr, and an allergist dr. I ve been going round and round with this and getting no where. It seems to move around both hands. I ve tried all the therapies but they still continue to be there. I was able to get about 70% of it but I m stuck with the 30%. What are the long term affects of having this problem besides scarring my skin??? Someone thought I may have black yeast but I m not convinced because it hasn t changed in the way it looks. Please understand I that I was exposed to these thorns from the Opuntia plant for 2 days in the midst of flying thorns unbeknownst to me. I was unaware of how the thorns hitch a ride. I thought only don t touch them . I was actually working on removing diseased plants. I can t emphasize how long I was being attacked, 2 days and 4 hrs at least.
