Prolonged neck pain, I have purchased new pillows twice, the expensive ones. Borderline migraines and migraines, I know it s not my sinuses because I m just coming off 10 days of anti-biotics, feeling nauseous alot. Very tired and run down feeling, that I can t seem to shake. Not sleeping well, but that s not unusual. I am on several meds, including morphine and a sleep medication. Can long term use of a narcotic have these negative side affects or should I be concerned about something else. I m going to be losing my health insurance soon, along with my husband s income and don t want to rack up a bunch of medical bills. Thanks
