Generally, I don't care to either read or post anything surgical. Yes, I have empathy for those who must undergo same. Just not my 'thing'. Few years ago, I left in the middle of a guest speaker time at a local AARP meeting. She was talking about "oral cancer  ". The club president asked me what happened. Mind you, this was just before we broke for lunch.  
Here, it is a little different. Hope we all read this at our leisure.  
 
I know the feeling of not being able to ride because of medical problems, hope we all can get back soon.
 
Btw, I have also missed out on some riding due to a recent 'hair transplant'. Dr. said no strees, no riding, no lawn mowing, no lowering my head below heart, etc. Wasn't sure this was too much "caution", until I bent over to pick up my shorts in bathroom, felt my head swell! Thot it was going to explode!  
YES! Dr. knows best. Stay with any/all orders.
