I have lower back pain that goes into my left buttock but not down my leg. Stiff in morning and after resting then eases. Cd it be arthritis? I'm 42

Spine Pain Options. This chronic pain in the distribution as you suggested is the result of an irritated nerve or facet joints or other injury typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease, etc requiring further evaluation by a spine specialist and may be candidate for facet injections/radiofrequency ablation and epidural steroid injection.
Could be. This could certainly be arthritis affecting your low back, that may be inflaming your l sciatic nerve-fortunately causing a radiation into your buttock only at this time (not your whole leg). Arthritis often causes morning pain and stiffness which ease through the day. Get evaluated and x-rays would definitively diagnose a possible arthritic component. Good luck.

Must Consider. At your age must consider a spinal nerve root compression secondary to a disc problem. Consult pcp. If ongoing you probably will need MRI for definitive diagnosis. Read more...
Probably sciatica. It is probably a sciatica, which is an irritation of a nerve in the back that causes pain to run down the leg. Some cases do respond to rest, others need more aggressive treatment before they get better. I would encourage you to be seen at some point if it does not get better. Thank you for the question.
