Mike, just wondering - how are things with the dizziness and "electrical shock" feeling? Are things better? Just wondering, since yesterday - out of the clear blue, my husband got up from a reclining position on the couch, and complained of a brief dizziness episode. It lasted a few seconds, but went away. (no electrical shock feeling though). He was Ok after that, but then when he got up again sometime later - it happened again. This is a new one on me - he has never had a problem with getting a dizzy spell like these before. He has been finsihed with his radiation for 6 months now. Going on 4 months post-surgery for modified radical neck dissection. There is still a "hardened" feeling under his chin, side of face and throat - so I don't know if this has something to do with it or not. He also seems to be a bit more confused lately as well. He'll forget or seem confused on simple things - but things he should know very well otherwise. For example - just the other day he was composing a letter to someone, and he couldn't think of President Bush's father's first name. I told him it was "George" - and that surprised me, since he should have known that because he was President Bush's motorcade driver when Bush Sr. was in office, and he came to town for functions, etc. Also - knowing what day it is earlier in the day - but forgetting in the evening. I wonder if there is any kind of restricted blood flow, being caused by the hardened tissue resulting from the surgery he had. Anyways - sorry to be so long-winded about this, but just wondering if you or anyone else can shed some light on what could be causing the dizziness and memory/confusion? It's not always like that - but just now and then it seems to be a problem. Perhaps it could be related to his thyroid? Thanks to all for your help.
