That’s not going to heal on its own, I’d bet they go for surgery.
In my experience NHS docs and surgeons are great, but they suffer from a lack of time and the need to ‘fix’ problems rather than explore options that might not result in a permanent fix.
If it’s starts going in a direction you’re not happy with, consider a second opinion from a private consultant- it’s not as expensive as you might think – think £100 for a half-hour chat, it changed my life! If you do decide to go down that route go back to hospital and buy a copy of your X-rays on a disc – it cost me £25 to get mine, private X-rays are about £100 a pop and they’ll want more than one, I had a CAT (might have been CT) anyway 15 mins with my arm in the big white tube £500 – worth every penny. My NHS consultant wanted to fuse my elbow because it was a permanent fix – he was so short on time I told him 2-3 times every appointment it was a MOUNTAIN BIKE crash, but he kept saying MOTORBIKE. Anyway private consultant put me on his list and 6 months later my elbow was better, they wanted 18 months healing before they opened it up again.
