I had problems of tennis elbow a year back, took medication, it was better but pain comes back once every 2-3 weeks, but most of the time goes without medication. Now since last 1 month I am having pain in heels, which lasts whole day, like plantar fasciitis. In general also I keep getting pain in joints like thumb, wrist etc. Got the RA factor test done, but the reports are normal. Vit D is slightly low,
B12 borderline low. No other issue with blood report. What can be done here. I feel in general my tendons are getting weak, any supplements that can help?
