(Quick reminder - Radiotherapy is measured in Grey (Gy) - the usual sort of dose is somewhere between 20 and 80 Gy depending on the type of cancer. The total dose is then fractionated and one fraction of the dose is delivered in each visit)
It is seriously painful now. I've got Flamazine cream to stop the burn getting infected and I'm on many lots painkillers for the next couple of weeks (maximum doses of Tramadol and Naproxen - yay drugs). I've also got a sick note for that two weeks as that's how long it's likely to take for the worst of the pain to pass. The oncologist told me to expect it to get worse before it gets better, I'm not looking forward to the worse. Right now I'd describe it as feeling like someone has poked 100s of needles through my hand and then poured vinegar over it.
So that's it. Unless I'm one of the unlucky ones who go on to metastasis my treatment is finished. I've got to back in six weeks to check how the burn is healing, then six weeks later I start a three monthly alternation between CT Scans and Chest X-Rays to watch for secondary tumours.
