Know you ar e not the only one . I have been thru 2TKR on the same leg then followed by 15 procedures to get me out of pain and swelling always been told nothing is wrong. This has been going on since 1st TKR in 2018 but I will not give in and I keep searching for an answer. Through being in touch with people on this wonderful blog and reading and ' practicing what I read' in the book ' MANAGE PAIN BEFORE IT MANAGES YOU' I have been able to take back my life , to a degree, not letting pain win. THERE IS HOPE OUT THERE , TURN OVER EVERY ROCK . THE PAIN MAY BE THERE BUT IT DOES NOT HAVE TO DEFINE WHO YOU ARE . YOU ARE YOU,, FIND WHAT YOU LIKE AND DO IT!! KEEP SERCHING PAIN DOES NOT GET TOO WIN
