Hi, i have a lower back pain which has been diagnosed as sciatica. The pain went away and has returned after a couple of months. I am having some tingling in the legs and lower back and pain all on my right side. This is going on two days now. I have a appointment with the Chiropractor today but have to make it through a full work day sitting down. Any suggestions of how to alleviate some of the pain minus a heating pad (which hasnt worked at all). Thank you!
