ok so my grandmother has shingle's

Well this was unexpected. She hadn't been feeling good  for a couple of day's it was as if  she was having flu like symptoms but no fever and then my mom called  and said I believe granny has shingles. She has  some blisters  that have developed.  So  I went over and I swear some were so big you could see the swelling through her pants, and then when I saw her thigh it was so red and blister  looked as if she had scalded herself which I knew she had not.  So off to the er to find out what was going on.  It is shingle's  the doc said.  So now  she is home  Thank God for that, on meds  and resting and of course the meds are making her sick to her stomach.  I have never seen shingles before but once you do  you won't forget it  that's for sure.
