pain and more pain

Today I made it into Aqua with a lot of pain. During the class my right hip - leg - frequently had trouble and my left knee did, too sometimes. At times it was fine, fortunately. When I got out my lower back hurt. I managed to go to Trader Joe's to get some groceries and get them home and put away but I still hurt. Took Tylenol Arthritis. Still have pain. I'm not enjoying this.
