Based on your description, you may have induced a misalignment within your neck. This can cause muscle spasm at the base of the skull, TMJ area, as well as neck and shoulders. It would behoove you to visit a reputable chiropractor in your area -- the sooner the better... I say that because small problems can often develop into more complicated problems down the road. It'd be easier to fix this now as opposed to later.
Thanks Doctor, I made an appointment with the doctor on tuesday and will ask him for a recommendation for a chiropracter.
