pain
"Full knee replacement used hydrocodon/acetaminophen for initial 15- days then Dr prescribed Tramadol for pain during physical therapy. First one I took I couldn't sleep and wide awake to 4:30am!!  Ok, maybe something else causing it? I read side-affects not many comments. I got by on Ibrophen during next few days didn't take Tramadol for 2-days. 
3-RD day by 6:00pm after working 8 hrs at desk job then on to 1-hr PT got home and decided to try Tramadol again. I took one 50-mg at 5:30pm and didn't sleep until 3:30am!!!  I also experienced itchy hand palms I noticed and lasted about an hour.  My pain isn't getting relieved either!!  
Can't continue, need rest, stopped taking and just using Ibrophen until I see Dr tomorrow!!"
