This thing has knocked me flat. Coming to nearly a month after the fall and it is still pretty painful. The good news is I have nearly full ROM and the bad news is it still hurts, and I've lost a lot of strength, even basic tasks, like putting on socks, are (almost) beyond me. I had a follow up appointment with my Doctor who ordered another set of X-rays AND a meeting with an orthopaedic surgeon. I 'only' did a grade II strain, with only minimal bruising and no super-obvious bump (although there is one there). Like you, I've become almost obsessive about researching it on YouTube and various other bike forums. A lot of people say they did like a Grade IV, rode 500 miles to hospital, did a couple of exercises with their PT and were good to go the next week. I've never heard of being referred to a surgeon after a Grade II tear...so I am getting a little worried. According to the 'generic' medical advice on the Internet (ala RICE), at/on around week 4 I should be healing and possible on track to resume light work duties, but it is not going as well as I would like and I still feel like I am a long way off returning to work (semi-labour intensive job in the event industry). I'm wondering of the belated diagnosis has anything to do with it as I did go to work for 3 days after my accident before the AC joint sprain was officially diagnosed, which really only gives me 3 weeks of decent rest so far.
I've been doing all the exercises prescribed by my physio, and a few more, thanks to YouTube and some resistance bands, but it doesn't seem to be making a huge impact. I go to bed each night wishing the injury away, but am reminded of it every time I wake up in the morning...
