Jo, two things. One, i always had crackers and peanut butter or a small tub of soft cheese by my bed and always ate something with my pain meds. Are you eating properly and on time? It is hard to have an appetite, but your body needs protein right now. I used some Protein drinks--called Naked Juice. It was yummy and I felt better after drinking one.
Second, are you resting as much as you should. i noticed that one day you posted a lot---were you sitting in a chair? or in bed with your knee up and a lap top on top of a pillow on your stomach? If the former--no wonder you had pain. I know, it is hard to recover!! And when you start feeling good somehow you thing--yea I am over it. But rest is critical.
I know you are our "Fearless leader" but, rest is really important now, even when you are feeling well.
