Themadpatter: First of all, you are not getting old. I should know, I am 62 also and not getting old!
My advice, don't cut for extended period of time. I know, doesn't help much with your hurt now, but remember for next time. So sorry you are hurting, no fun at all. Sometimes applying ice to where it hurts can help. Ice for the first 24 hours or so (only keep ice on for 20 minutes at a time), then heat for the next couple of days (also only 20 minutes at a time).
Good luck! Hope you heal quickly.
