Yes, its terrible pain. A lot of it is nerve and a lot of it is muscle. Depending on how bad the impingment is, will determine pain level. The percocet should definitely help. I found that you truly have to listen to your body. Reducing activity to almost nothing and finding a comfortable position while sleeping/sitting/lying down is important. I am actually almost ready to go back to work due to a lot of doing nothing and seeing a mackenzie physical therapy specialist i got injured in september if that tells you how long it takes. Degenerative discs are more painful than just an impigment.
