I have PAD along with degenerative bone disease of the hips and back, I usually get trigger shots in the lower back and hips through pain management, however the last shots were a month ago, I had a lapse in insurance and unable to get the shots. Lately, I have been having excruciating pain in left leg, with swollen left foot, unable to get out of bed, also my leg locks up at the knee and I require assistance to relax my leg, which is painful and have been having to walk with a cane, i dont know what is going on and I am scared. Can you help me.
