So sorry you're having back pain. Back pain is miserable pain.

Trying to find some comfort is hard when so many things have failed.

After surgery, you are altered and it becomes even more limited to what may help you. Does you doctors have any suggestions for you to try?

But here goes some thoughts for you.

Lidoderm 5% patches, LED/infrared light therapy pads (Skin Solutions out of Vancouver, Washington), yoga (don't laugh - do what you can with the poses. It gets easier) ... Relaxation and breathing techniques. Oversized tennis balls (found in pet stores - mine are not firm at all. They are actually not inflated all the way. Miracle Therapy Balls. they're soft, green in color. I'm on my iPad or I would Google links for you to look up.)

A TENS unit or neuro stimulator is also helpful to me. Aqua (water) therapy helps me too. Doesn't cause me problems.

The simple things... Smoking/nicotine is not good. Inhale water. Sugars in food are becoming increasingly known to cause joint and many other health problems.

I view things as positives or negatives.

I found that at the end of my shower, if I turned the water to cold and let it hit on my back, that helped.

Also, a heating pad is good, comforting, but try to limit it to 30 minutes or less at a session. Heat on a microscopic basis can cause swelling. Swelling causes pain.

Changing positions is necessary. You probably know that.

Take care...
