I have never been sick or really sick, in march my neck started hurting or a dull pain in back of head. Was really worried so I quit smoking cold turkey. Been to the doctor because of my worrying and it continueing to may. Ct scan rulled out head problems, spinal tap ruled out other stuff. Now still getting dull pain at the big back bone just above the sholder blades. Left eye keeps watering, dull pain in different parts of body. Doctor says tension headache. Should I worry. I do sit in front of a computer 8 hours a day as my job, but was doing that for about 5 months and this seemed to come on quick.
