Re: new Dr.app
Assuming he recommends surgery, I would write down (or have him) the names of the procedures, to explain exactly what is entailed, how long the recovery period, how long would you be non-weightbearing/in a cast/walking boot/etc., if the Evans procedure is done--bone bank graft or from your leg/hip, success rates, complications you could see...And Cosmic1 had some good points too. See what your gut feeling is with this dr and with the first one.
DPM=doctor of podiatric medicine. They're not medical doctors, but are trained specifically in treating disorders of the foot, conservatively and surgically. An orthopedic surgeon is a medical doctor who may or may not have special training on foot/ankle issues.
I had surgery last May, including the Evans osteotomy and posterior tibial tendon repair, and am doing pretty well now, 5 months later. My other foot is doing poorly and I will likely have to undergo the same stuff on that side, but there has to be at least 6 months between the 2 procedures to allow the other to heal more fully. It is tough surgery and the journey is long...but so far I'd say it's worth it (pain gone, walking normally...). There is only so much that can be done non-invasively or conservatively...then it's time for surgery to hopefully fix it permanently. Good luck as you have your 2nd opinion! Take notes and let us know how it goes!
