Friday was 2 weeks post ACDF with donor bone and hardware at c6 & c7. I woke up fine. I went for my walk as normal this morning. No problems. About 2 hrs ago I started getting more pain in the back of my neck and headache. I took a lortab 7.5 & a flexeril 10 mg. I ended up vomiting about 30 min ago. I have not done anything today. No lifting of anything. Just walked, took a bath, then have been on the couch all day. I am also having some tingling in my fingers on the left side.( this is the side that was affected before surgery, The pain was completely gone after surgery. I have had a few twings in them every now and then. The dr. said this would happen. But I am worried about the pain and the headache.. Please someone tell me this is normal.
