I had a sacral nerve stimulator put in on feb.7th. I am now having sever pain in my lower left side of my abdominal are those 2 things related?

See your doctor. If you think the nerve stimulator is causing the pain, then you could try turning off the device and see if your pain goes away. Regardless you need to see the physician who implanted the device.
Evaluation needed. Any pain following a procedure should be discussed with the physician who performed the procedure, as they are better qualified to answer your questions. Recommend calling his office.
