I smoke marijuana for my RA and IC pain, although, I have bites . This has been going on for about two years, I say bites because they look like bites with a tiny hole in the middle, it itches something terribly. I have gone to the dermatologist and had allergy lab panels and scratch testing done with negative findings.I was already smoking before it got really bad, these bites are all over my body and I can actually feel something sting me. I have yet to see any insect on me. Is the marijuana a possibillity? Thank you, Y. Rodriguez
This may also be possibly caused due to any other medications you have been consuming for your other issues with RA like painkillers or NSAIDs or any other disease modifying Chat Doctor.  If you consider that your lesions increase after smoking marijuana, then you may consider keeping it for pause completely for a few days, even don't consume cannabinoids in any other eatable form. If lesions keep on occurring, then it may be possible that it is happening due to other medications for your RA. Even RA as itself can cause certain skin lesions, basically consider having opinion with your dermatologist and a rheumatologist.
