I was diagnosed in the fall of 2018 with Primary Cutaneous Extra Nodal Marginal Zone Non-Hodgkins Lymphoma, sorry, I don't know the abbreviation. I decided to go the watch and wait route. Last fall I was being considered for a clinical trial for ongoing problems in my left leg. The CT found that I was a candidate due to May Thurner syndrome, but they also found a deep tissue mass/tumor in that leg that the Dr. said needed to be taken care of before he'd address the other problem. I had a biopsy and it came back as the same type of lymphoma. I had a course of Rituxan in December, once a week for 4 weeks, which I had a bad reaction to but completed. I had to cancel my follow-up in February and will be going tomorrow for the follow-up. I found a lump in that same leg about a month ago and have been having symptoms that may or may not be directly related to the lymphoma. I still have a big bill and I want to limit testing/imaging. Does anyone know if an MRI would show everything that's going on? I don't want to appear clueless when I see the doctor.
