Cervical spinal stenosis how to lessen pain and what pain meds work best had trouble with physical therapy because back is in spasm pain was unreal?

Cervical spine pain. Each case is different. See orthopedic spine doctor or pain management. Consider postural changes, sleep changes with different pillows/positions, gentle massage, yoga, meditation, modalities/laser therapy, acupuncture.
Would see pain doc. You may benefit from procedures such as epidural steroid injections that would allow you to get through therapy. If the pain is specifically from muscle spasms, you may consider asking your physician about medications like Baclofen or tizanidine. If you have more nerve like pain, ask your doc about Gabapentin or lyrica (pregabalin). Hope this helps!
