Unsure what to do now....pain is unbearable

I just had my MF done on 12/14/2011. I went in for knee cleanout and came out with MF. NWB. I have 5 children and I have always been active. This being stuck NWB and mainly stuck in bed or on the sofa is almost too much to bear. I do it but I am in a straight leg brace and can't take it off for any reason which is really painful. I can't feel the ice wrap they gave me and i don't like taking pain meds (they make me sleepy...with 5 kids that is impossible). I screwed up and WB lastnight to make dinner now my knww in the front near the stitches feels like someone is poking me with a hot needle.
any suggestions to help me out and how long i will be like this?
by the way i do not have a cpm
