Roger - are you being treated at the cancer center in Hamilton? If so do they have a rads clinic? My mom was treated there (3.5 pack a day smoker - with lung cancer) I can't remember if they had a standard walk in rads clinic. PMH does - it's a drop in if you have any issues - call them see if they have a drop in and they'll have someone (likely your radiation oncllogist) take a look at it. if he's not available here's usually someone around who can take a look - plus the nurses at our clinc have seen it all - they could probably tell you right off. This may ease your mind until you can see your team! good luck. Plus chemo affects all cells in the body! And there's a system called the fight or flight response in play when you are stressed - think about how stressed your body is during and after treatment - this causes low circulation anywhere except vital life processes.. So your skin hair nails etc. don't do things the way they used to - they can't - once your body starts up these normal processes again while you are healing there are bound to be some irregularities. Take care -
