I have had Achilles tendonitis for 4 years in my right heel.  4 years ago I had a fall and it didn’t seem too bad but when I drove the car my heel would ache after 20 minutes and after about an hour my leg would start to swell up.  Eventually I took it in to be checked out and it turned out I had some small tears in my Achilles. I went to rehab from hell one time and never returned.  They gave me deep tissue massage and it was agony.  The worst part was that the rehab expert masseuse sadistic @#$%^&*  hanging on to my foot refused to stop when I asked him to give me a break for a minute.  Well that was a disaster as I have issues with being controlled so I became hysterical and he still didn’t let go. JERK!
