Sadly, I agree with Jonah. Two weeks physio is unlikely to bring you back to full fitness, doing too much too early could have long term implications. Having also suffered a broken wrist some years ago, I was really surprised when the plaster came off at how much loss of use I had suffered. Everyone is different, but, in my case it was six to eight weeks before the recovery was complete. I had to cancel a holiday,on the recommendation of my insurers . I was told that I would not be covered in. event any complications. I know this isn’t what you wanted to hear, and I do wish you a speedy recovery, and, a fabulous time in Sri Lanka whenever you travel
