I had it when I was 12 years old (that is 57 years ago so things were different back then) I had to stay in bed for a month, could only get up to go to the bathroom. It was summer time and all my friends and siblings were out having fun. No tv to watch so I read, read, read and listened to the radio. The DR came to my house every day( I told you things were different back then) and gave me a shot of penicillin(sp), the new wonder drug. I never did, thanks goodness, have heart trouble. The pain was all in my legs and all I had to take was asprin It didn't help much. Leg massages from my mom helped a lot & so did Grandma's chicken soup(I think it was the attention). Please let her know it is going to get better. My love and prayers go out to her.
