Pain in lower back, leg, and lower mid arm?

It could be anything, nerve problem, muscle problem, kidneys or a number of other things...It is impossible to answer your question without knowing what the actual problem is. Ask your Doctor for a referral for a CT or MRI scan.

The wrong type of treatment or exercises can do more damage than good and you need to have your back properly diagnosed prior to ANY treatment.

Again you do need to have a CT / MRI scan or such done before allowing ANYONE to touch your back.

Get a professional opinion from the radiologist doing the scan in his report to your doctor and then go from there.

Normally, I would not answer a question like this as my expertise is generally in medication but I had severe sciatica while I was pregnant with my 3rd child (after having had twins) and I had sciatica so bad that I was finding it difficult to walk. I tried massage therapy and physical therapy and could not take medication

I went to the chiropractor and the pain was instantly relieved. My hips and lower back were out of alignment because I had carried twins the year before. On occasion a Doctor of Osteopathy (DO) can also work but they usually only work on one joint at a time - the chiropractor will do your whole back which works faster. Anyone who does not believe in chiropractors will tell you they are quacks - don't listen.

I don't necessarily believe that chiropractors can cure things like diabetes but they can definitely relieve some types of back pain especially if a pinched nerve is involved which is usually the cause of sciatica.

See a chiropractor. You may have a pinched nerve or strained muscle.
