I am surprised you don't have post op medications. You should have been given enough for the first month at least. I am not an expert. However 4 weeks out is a short time. Not sure about the whiplash, but I do know I had some very bad pain 4 weeks out myself. I think mine was muscle spasms. Soma a medication helped me. Your doctor should not just dismiss you if you were in tears. He has an obligation, to see you though these first few weeks. Take it easy, do not strain. Call him back and insist that he at least gives you a call and something to take the edge off. If at 6 weeks you still seem to have real issues, get back into seeing him. Did he take an xray, after the surgery and show you? They usually do that and check to see how you are healing. Plastic was used in the disk space? This was a new thing for me to learn about. I only thought two choices were available, cadaver bone, or bone taken from your hip or pelvis. Do not hesitate to call your physician back. Your neuro surgeon should help. If not, contact your PCP and tell him you are not getting satisfaction from your surgeon. He may be able to call your surgeon and talk to him. My own PCP did this for me regarding the pain specialist after my surgery. I hope you feel better soon. Give it a bit more time, and get some medication, outright ask for some OK? I wish you all the best. ginnie
