I had gamma knife radiosurgery one month ago. Everything went fine and I'm very grateful. The lidocaine and the head frame was painful but they were fast at getting it attached. The first few days I was in pain and was dizzy and nauseous. I gradually felt better until last week when my head and neck both felt like they were going to explode. I was dizzy and nauseous again. I tried advil, tylenol, decongestants, and antihistamines. It gradually improved after a week and I'm back to feeling somewhat better. Has anyone else had a similar situation where there is a feeling of pain and pressure in your head and ear and neck a few weeks post gamma knife? I've been very tired, but I understand that's a normal radiation side effect. I also have hashimotos thyroiditis and graves disease. Most of the time I am hypothyroid but I can easily become hyperthyroid very quickly. I'm waiting for some thyroid blood tests to see if my thyroid levels might be off. Has anyone had an increase in thyroid problems post AN diagnosis? I still have my thyroid and have taken methimazole or levothyroxine depending on my thyroid levels. My AN was on the left side, 1.6 cm, very close to my brain stem. Diagnosed April 26, 2022. Gamma Knife 8/11/22.
