Thanks for this thread, Uncle Tan. Stickied! On the subject of Achilles tendonitis and recovery, here are some nice videos to watch while laying up in bed with busted tendons! This is the first of a series of 4... http://www.youtube.com/watch?v=PwMebcSUdgw
I wish that I knew about these common injuries earlier. I always used to think that an ankle sprain wasn't a big deal until I experienced it myself recently... I couldn't actually walk the day after I did it Luckily it's healing quite well now but I'll be a lot more careful in the future, and now I know what to do if it happens again unlike before.
My physiotherapist says shoulder injuries are very common for those who work in front of the desk a lot and is worsen by improper techniques. I was one of them. Proper techniques will greatly reduce the chances of it, but too much desk work will weaken the shoulder muscles, so it becomes an evil cycle.
As noted, physiotherapy helps, but only in minor cases. Best is to seek help early and practise proper techniques.
If you work in front of the desk a lot like me, it is also advisable to do the exercises your physiotherapist recommends conscientiously, particularly if you play a few times per week. That's the best prevention against such injuries.
