I am not knowledgable about some of what you asked. I think it is important to ask your doctor. I remember in the start I was nervous to but now I come up with a note pad and binder. You deserve to get your concerns and questions answered. I would also ask the doctor if they feel this infection could be impacting your nerves and get their thoughts on that.
I always fear things making me worse since it has happened so now I ask my doctor what will happen if it makes me worse or will it. Then I try to weigh th pros and cons and stay in the moment. The worry,anxiety,and fear does not help in this condition. Easier said then done to not though and those 3 words are a huge part of me. I am really working on relaxing though.
Hope you feel better
