I was first diagnosed with Capsulitis in which the Dr wanted to shorten my middle toe and put a pin my foot. I think you are doing great in getting as many opinions as possible. I would really try and seek out a foot specialist next.
I found a little explanation for you.
Keep us posted on your progress.
There are several possible ways to treat the acute symptoms of capsulitis: rest, ice, anti-inflammatory medications, steroid injections, massage, physiotherapy, shoe changes, and padding are just a few.
Orthoses designed to redistribute weight away from a prominent bone is likely best for chronic capsulitis.
Surgery to repair ruptured joint capsule may be indicated when it's torn. If the metatarsal bone is "dropped" or too long, surgery may be considered to lift or shorten the bone. Over a dozen procedures may be considered for this, but two commonly employed for this procedure are the Jacoby Osteotomy (a "V"-shaped bone cut made from top to bottom, allowing the bone to elevate) or a Weil Procedure (an oblique bone cut that allows the bone to be elevated and shortened.)
