OMG I feel your pain. Take care of yourself and know you are blessed to have such a wonderful husband by your side. Bet he even typed the post!
About 10 years ago I was multitasking with a 3 pound Chihuahua in one arm and a full laundry basket of wet clothes in the other. That small step off the porch (known as a cinder block) was not enough footing for me and BAM down on the right knee. Chihuahua went flying, clothes all over the place. Ringing in my ears from the pain. I was speechless (for maybe the second time in my life!) and ended up tearing my maniscus (sp?) and the knee hasn't been the same since. Dog was fine - although I could have crushed her. Couldn't handle crutches because of the carpal tunnel and trigger finger in both hands. I made it thru but with pain meds by my side. I now have RA in the right knee.
Sigh.....wishing you a speedy recovery and hope the time goes fast till you're back at the machine.
