If it's been 6 months and you are still having a lot of pain despite the physio etc, perhaps you should try and get a second opinion from an expert - can you find out if there is a hand specialist orthopaedic surgeon in your area? If you can't get a referral on the NHS, you might want to consider paying for a private consultation - maybe worth it to sort out something that is clearly having a big effect on you?
Good luck, hope it gets better
Ligaments and tendons are mostly collagen and therefore pretty much always have a fairly poor blood supply. For this reason it can take longer for a ligament injury to heal than for a bony fracture, particularly if it is being re-injured regularly, no matter how lightly.
Even so, I agree that 6 months is too long: Demand a referral for a second opinion from a hand specialist (or, if you've already seen one, another one), every hospital will have one. Then, having asked for a second opiniont, trust it, though if they don't suggest an MRI suggest it yourself to look for flake fracture fragments, bony spurs etc. If they suggest surgery ask for ALL the information: The pros and cons of operating
and the pros and cons of
all alternatives. Then go for the op if it's the right thing. If they suggest immobilization, let them. If they suggest physio, go to physio. It may be that you won't be able to play for several months or even a year or more: Accept it and don't push it too early or you may be back to square one.
Yes, you're a pianist and this will have a huge impact on you - it clearly already has. That isn't their fault and it may well be that they appreciate the problems, they just can't magic up a solution that doesn't involve lengthy rest.
When Beckham, Owen, Rooney et al. fractured their metatarsals it was said with some truth that if you treat these fractures they heal in about 6 weeks, but if you don't it takes 42 days! The same sort of thing is true with any physical activity: You have to treat the injury properly - you can't rush it, NO MATTER how much you might want to.
Best of luck, though: sounds horrendous.
n.b. many sympathies - I caught the fingers of my left hand in a circular saw once. Whilst I am acutely aware that I am very lucky still to have fingers, it was 2 month's before I could scrub up and work (I'm a surgeon, though not orthopaedic) and the scars were sufficiently tender that I couldn't play any musical instrument at all for a year. It was immensely frustrating at first, then depressing because I thought I would never play again. The day I played a guitar again for the first time was such a good day!
