Ok, I have what feels like nerve pain on one side and its mainly on my left buttocks. Does that sound like nerve pain?
That isn't really is description of pain. Do you know what nerve pain feels like? Can you tell the difference between nerve pain and regular pain? I have tried to help you with this in two other threads that you have posted this question in,and I will try again. There is a distinct difference in pain between nerve pain and regular pain. Pain that is not controlled by regular pain meds and that is a deep burning, throbbing pain, pain that seems to ache so that you cannot find a comfortable way to sit to find relief, is usually nerve pain. It is caused by a compressed nerve or a nerve that has been damaged.
Damaged nerves can be determined by having a series of tests that can tell if a nerve is still active or if damage has occured. EMG is the name of the test that is admistered. They are not pleasant, but will show how badly damaged the nerves are.
Your damaged shoulder or neck has nothing to do with the fact that you are having pain in your buttocks. The area of your back that controls the nerves in your lower lumbar area is not the area that is directly connected to the upper area of your neck, nor is the high neck responsible for the lower back pain.
If you are still having issues, why don't you go into your GP and get a referral to either a good back doctor, or have your doctor get you into some PT to help release the pressure against your nerves that are being pinched. That might help relieve the pressure off of the nerves. Your other option is for meds that are designed specifically for nerve pain. They have found that meds that were designed for seizures work extremely well for nerve pain. The biggies are: Topomax, Neurontin, and the newest is Lyrica. They all have their side effects, so you need to consider that before you start taking them.
good luck.
