Sorry you got it, that really sucks- I have heard it can be very painful and uncomfortable.  Hopefully your doc put you on a good anti viral med that will shorten the course and severity and some good pain meds.
 
	 
 
	Related  story - I had a weird reaction to the shingrix vax which is a two course vax.  Last year about July or so I got the first shot- I have never had a vax hurt so badly for so long.  My shoulder felt like Mike Tyson had punched me in it every day for about two weeks. Even after that I had alternating pain and a weird weakness when lifting that arm into certain positions for several months.  Due to that,  I never went back to get the second shot.  Hearing about your experience I may reconsider it.
