I am 32/m. i'm having lower back pain with nerve pain in my left leg. after taking bed rest the back pain has reduced but the nerve pain is till there?

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.

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.
