My twenty year old son has a low back pain for a month, any advice.?

Stretching and heat: Gentle stretching and heat can be very helpful. Seeing an osteopathic physician who does manipulative medicine might also be very helpful.

Be carefull: Back pain in kids should not taken lightly, should be investigated and treated accordingly.

Check it out: Liw back pain that persists can be a concern. Get your son seen.

Core Exercises: Typically core strengthening exercises are the best to help relieve pressure and forces in the spine. I would try and google some or look them up on youtube to see descriptions. If you can do them yourself, wonderful otherwise ask your doctor to get a referral to a good physical therapist for further assistance.
