<human>: HI 
<bot>:  I suffer with severe knee pain (need a replacement on my right knee) but why my pain goes through my legs and severe foot pain and specially at night is worse. Suffer also from insomnia I can't get to sleep until 5 - 6 or 7 a.m. I go to bed at 3:00 a.m. because I am not sleepy and stay in my computer trying to get tired to go to sleep. How I can get help with all these problems. I take pain medication and sleepy medicine but doesn't help. Thanks for your help. Maria S.
