Back in my 30s in the mid 1990s, I experienced constant pain in one wrist, which I attributed to weight training in the gym.
I resorted to constantly wearing a neoprene wrist support.

Eventually I somehow had the idea to phone the UK Musician's Union for advice.
They immediately booked me in to see their specialist Dr in London for free,
even though I mentioned I wasn't a member.

I was told to go to the appt and take my guitar.

The Dr needed to see how I played, and if I had any bad habits causing my pain.

It's so long ago I can't remember which wrist, or his diagnosis and recommended treatment.
Vague memories it might have involved dunking my hand in either hot or cold water
and doing some stretching or tightening exercises whilst submerged...???
I can't remember for certain....

I once turned up for a band audition in Camden,
[a record label boss - friend of a friend - was forming a backing band for him and his wife]
Basically the guy was stoned, too stoned to concentrate on running through his songs,
and all he could do throughout the audition was talk about my wrist support and why I was wearing it...
was it a fashion statement...???

Funnily enough, I never heard back, and found out he never managed to get his band together, and passed away not long after.
