This was where my sports injury therapist (SIT) came in.
So, after a full examination, and about six weeks after the injury and with my upper ankle about twice the size it used to be normally, she set to work with deep tissue manipulation. On each occasion firstly of the calf, which had also become very tight (too sore to stretch) and then into the area of the tendon itself. Mainly to both sides of the tendon before rounding off with a full frontal assault on the ridge of the tendon itself.
The idea of this is to break down all the scar tissue - she called it "crystals" - that was causing muscle and tendon fibres to fuse together. Separating out the fibres again, with the eventual aim of freeing the tendon completely.
I have to be quite frank here. Although I absolutely recommend deep tissue manipulation - it bears no resemblance to therapeutic massage. During the sessions with my SIT I can honestly say I had to endure the worst pain I have ever experienced in my life (51 years). And this voluntarily!!
There were times I was gripping the couch so hard I thought it would actually break and there were huge dents in my biceps! Sometimes I would be moaning and banging my head up and down on the couch. Sometimes loud yelling. Always heavy and laboured breathing.
But in 12 months only once did I have to ask her to stop because I thought I was actually going to pass out.
She never bruised me once, nor even made the treatment area red.
