I have arthritis in my lower back. Originally doctor said arthritis around 2 deteriorated disc. Then called it spinal stenosis.Epidurals do no help any more. Have difficulty in morning hours getting out of bed. Take pain meds and walk when I can then maybe I can be up and active 4 to 6 hours. Late in day I feel pulses moving under the skin and can actually see them as well. Feels like something lightly running in my legs. I m seeing only a pain management doctor now, but contemplating seeing a rheumatologist. Any suggestions as to what this might be. I am retired and 68 years old.
