Quick reply here...
1 - The earlier you can begin movement, stretching and weight bearing, the better. The consensus among my healthcare providers confirms that my long nwb and splint, cast to boot period is a huge contributing factor to the issues I'm experiencing now thanks to the scar tissue.
2 - For lingering pain issues and scar tissue issues, look into physical therapists certified in the Graston technique (specially deals with scar tissue). My initial experience with it several years was unbelievable. Scar tissue around knee from a surgery 15 years prior was treated and knee issue resolved.
I decided to seek this treatment out again due to continuing problems 10 months post op (had to do this myself, don't rely on the surgeon or doctors office and don't go to one of the big or franchise therapy places. Look for small or private practice therapists where you will spend your entire session with the therapist).
After one visit, my first visit a couple days ago, the results have been remarkable. The Achilles tendon had a lot of scar tissue built up around it, a pocket of fluid in the peroneal tendon area was addressed, possible issues with that nerve being compressed were addressed, scar tissue on front of ankle and in foot addressed, etc. I am walking better and ankle and foot are starting to feel more normal again. A lot of natural movement of parts that should move was restored.
Can't wait to go back again next week. I FINALLY HAVE HOPE that I will be able to resume jogging and other activities (and wont be stuck wearing sneakers or unattractive orthopedic looking shoes forever). I might just get my life back!
3- if you are opting to pursue conservative treatment, by all means go ahead, but decide ahead of time what your time or money cap will be on it vs expected outcome. I spent about 7 years in conservative treatment mode and it sickens me to think of the thousands I put into it.
Furthermore, prolonging the ankle surgery only caused issues and damage to foot that could require another surgery. So stress fractures, dropped metatarsal, broken foot bones, neuromas, and increased ankle instability occurred. I hate to think about how so many of those things could have been prevented.
