My PT tried cupping, needles w/ electric stimulation, massage… exercises…etc. Not sure why my back and knees lock every day at the same time- after 4 pm. My pain doctor didn’t offer lidocaine shot. I was reading about cortisone shot and osteoporosis. Most articles say that long usage of pills would affect bone density but occasional cortisone shots not that much. I am thinking to start lowest dose on Tymlos and slowly increase. I almost always have bad reactions to any sort of medications. For example anti inflammatory affects my vision- I barely can see. So, I avoid them. I am going to ask doctor about lidocaine. I used 5% lidocaine patch- didn’t help me much. Not sure what to do.
