Had my left knee replaced due to severe stage 4 R/A. Was sent home at 11pm the same day. The next morning went to use bathroom and my knee buckled. The next 2 days it bled thru the dressing. Finally they called me back to hospital and changed dressing. Now I am 4 weeks post op. Still on pain meds and started physical therapy. The PT gave me a massage on the incision to break up scar tissue.( Pain level off the charts) she also had me do excercises for 30 minutes non stop. My ROM was 93. Ever since that session my pain level has been 8-9. The PT said she was impressed at my progress considering I had a setback with the fall, she scheduled me for knee excercise classes. Can I get feedback on the knee classes. I am thinking of not participating. I am so glad I found this forum.
