My brother had this when he was very young, that was over 50 years ago. I remember he was in bed a lot, and everything hurt. Don't remember much else, except he was ill a long time and he eventually did get better. You know medicine today is so much more advanced. He had mild heart problems for a short time, but was still able to serve over 30 years in the US Army with 3 overseas tours. Prayers for a speedy recovery-
