I don't know where in the south you are, but I experienced alot of what you are going through. Had Lumbar fusion locally in 2011, didn't go well. On the encouragement of several physical therapists, I ended up at Jewett Orthopaedic Clinic in Orlando. They are unique in their practice as the Drs can only operate on one area of the body...ie...back dr, foot/ankle dr/ shoulder...etc. I fortunately found a Dr there that redid my surgery and I am back 110%. Truly amazing.
I have since had achilles tendon repair there...not by a podiatrist, but a orthopedic surgeon that only does foot/ankle.
PM me if you would like more info...I love sharing my story as my outcome was amazing. There are good Drs out there that truely love what they do.
