Hi, i have been reading a lot of these posts and comparing them to my symptoms, i hope to get an answer, since March of last year 2020 I felt pain in my left side and a pain in the upper left side of my buttocks after a few days pain was gone, then June I went for a long walk and the next day my left knee was swollen, after a few weeks I went to see my doctor, of course, he said not to worry, he did tell me to use a cold pack for 15 to 20 minutes 3 to 4 times a day, the swelling did not go away, he gives a referral to see a neurologist he did an EMG and said there was nothing wrong with me, I went to another doctor and I went to see a rheumatologist same thing said everything is fine with me told him my left knee is swollen told me not true, finally, I called the doctor and finally I got a referral for an MRI the spine I am waiting for the results, it does take two weeks, so right now I feel pain on both sides of the knees I was wondering are these the symptoms of rehumatoid arthritis or peripheral neuropathy also I feel on both legs some tingling. I do hope for an answer. Ty
