well that is if you don't have your pain killers. The tiny battery pack insert into my chest and resting on my pec muscle hurts like MF! Oh MFCS (abbreviating curse words) hurts to type too much with left arm)! Got the ONS (Occipital Nerve Stimulator) implant this morning. My hair looked great before hand, was clean, shiny and stick straight. Now it's all F-ked up. BOO. What hurts? Not the things resting on my skull. No they just tingle a little. They woke me up during the surgery and tested it and oh boy weird sensation being awake and knowing that someone is working on your brain at the same time. HOUSE does not do justice to the weirdness the patient feels while this is happening. What hurts is where they had to snake the leads down inside my neck - OUCH- and where they impanted the battery in my chest just above my left breast. It didn't hurt at surgery center but then came home and started dry heaving, then got a migraine from anesthesia as I told the anesthesiologist I probably would. The anti-nausea med is the same one my sister is getting during chemo - zofran - and it triggers migraines in her and damn if we weren't somehow connected by some telepathic string. Cause it happened to me too. Anyway cannot really raise left arm to high without moving pectoral muscle that the battery pack rests on. So my thought is breast implants must hurt like hell. have to go get pain killer from pharmacy cause Neurosurgeon laughed when I said I have Tylenol for pain control. Took pictures on head and neck before and just took blurry pics of the aftermath. Enjoy
