I have three irregular hard knots come up on the back of my head. All on the right side. No injuries to blame except old falls. They are very sore to touch and causing headaches and dizziness. Should I see a doctor or wait it out. I have rods in back S1 to T10, plate in neck all due to degenerative disk disease and joint disease. I have an artificial left TM joint. Suffer from arthritis and fibromyalgia. Recently has esophageal ulcers and treated for them. Monday of this week had another scope and found two white areas this time and took biopsies. Ulcer biopsies were okay. Don t expect anything to worry about the recent biopsies taken.
