I am 10 weeks into the same injury - I tried to 'soldier on' for a couple of weeks, but had to stop mid round as the pain was killing me, literally crying after I tee'd off on the 9th. Tried again about 2 weeks later and allthough I could 80% swing once I was warm, the next day was agony. I have since done nothing for six weeks and at last am starting to heal. There have been times when I really thought I had this for life.
The lesson is, if you get this injury, just stop and wait, you'll need at least two months and just need to get your mind around it.
Anyway - I've got a round booked for Xmas eve, which will be about 12 weeks after the injury - can't wait and keeping fingers crossed!
At least it happened in the winter!
