Article Comparing Alcohol Injections to Cryosurgery
http://www.podiatrytoday.com/article/2691
I'm seeing a lot of surgery horror stories. You should consider and research cryosurgery before you take the plunge.
Alcohol
-alcohol causes tissue irritation, and ulcers or abscess may occur - can be very painful
-may cause formation of stump neuroma
-4% concentration of alcohol sometimes not strong enough to cause chemical neurolysis
Cryosurgery
-minimally invasive and takes approximately 15 minutes to perform
-no incidence of stump neuroma formation
-short postoperative recovery period - only need to reduce activity for few days
-success rates with one treament run 80-90%.
-cryosurgery can be repeated without problems
-available for heel pain, Morton's neuroma, plantar fasciitis and many other painful foot conditions and masses
