I had a cold last week sunday2/29 then woke up monday with a stiff neck( my left side) my cold went away by wed, but the stiffness and sorness in my shoulder didn't. I have muscle relaxer from the last time i had this. i took it every night along with iburophen(4 tablets-perscription strenght) right away on monday. It hurts im unable to turn my head to the left or up or down. By Thursday I felt my neck getting swollen ( doesn't hurt to eat or drink) I went to the walk in doctor on Friday 3/1, he said maybe the cold settled in your neck& shoulder gave me another muscle relaxers and told me to take naproxen instead. its is day 7(3/6) and still no change. I called my doctor and they said get a massage and take iburophen w/ the muscle relaxer, I got a massage stiffness much better soreness in shoulder still there but now I have a sore throat. what can this be?
