Relief pain sciatica. You mean pain of sciatica.Sciatica is caused by irritation or compression of one or more of the five spinal nerve roots which comprise sciatic nerve.It can be from herniated disc, spinal stenosis or piriform syndrom.Your doctor will be able to explain what these are.The treatment is non steroidal pain meds like motrin, muscle relaxants, bed rest is controversal, and some time physical therapy may help.
Pinched Nerve. I would suggest seeing a pain/spine specialist to evaluate you further to evaluate what level and what can be done to treat you. There are interventional treatments besides medications and surgeries that might reduce or eliminate the pain altogether.
OMT or Analgesics. There can be many reasons for 'sciatica'. The piriformis muscle passes over the sciatic nerve. A spasm of this muscle can cause pain down the leg up to, or below the knee. This could be from the piriformis muscle itself or a secondary component of iliopsoas spasm. Osteopathic doctors (dos) are trained in omt (osteopathic manipulative treatment) and may provide relief to your symptoms.
