Doing yoga this morning....could only do 20 mins. I use to be able to do the entire 45mins. I couldn't lie down on my stomach because of the balloon feeling under my right rib cage..and I didn't have any more strength or energy after the 20 mins. I want to cry...I know I have to adjust my exercise program because of this disease, but I really need yoga for meditation and breathing reasons. My back has been hurting in the middle and I tend to not breathe deeply when I am in discomfort. Just feeling a little depressed about all this...trying to keep in shape is becoming a real challenge...I am fortunate in that I exercised my whole life, but having trouble coming up with solutions. Did anyone find out what that balloon feeling under the right rib cage is?
