Is there a cure for Morton's metatarsalgia?

NO! I've had it for 20 years and I've seen at least 10 foot doctors and orthopods. No one has been able to cure this terrible condition. I've been through shots, splints, orthotics (at least 10 different pairs), plus physical therapy. And, NOTHING HAS HELPED. I sit here with my foot taped and elevated, hoping for a cure sometime before I die. I'm 66 and this problem started when I was in my early 40s. I also have plantar fasciitis and have recently developed a plantar fibroma that my doctor wants to remove with radical surgery. I'm holding off. Waiting for some new treatment that offers real results.....and hopefully, a CURE.
