I don't know if I'd dare go mixed grip now for fear of tearing it completely off the bone. I'll learn hook grip now. I got a referral to an orthopedist to determine if I "deserve" an MRI, and then possibly surgery like on the other arm. It was hard getting that first surgery, I had to beg and cry LOL. Things move slow here. Shitty system to say the least.
While you may be nervous about being exposed to attack due to a shortage of missiles, you'd get that MRI and surgery over here.
Our healthcare system is far from perfect, but I've been able to get done what I've needed in terms of stuff like this.
