Surgery may be an option for Achilles tendinosis if other treatments, including physical therapy, ultrasound, massage and shockwave therapy, fail to bring pain relief. General anesthesia is commonly used. Regional anesthesia that numbs the leg may also be used.
Anesthesia problems are at least of two general types. One is acute effects on the brain, in particular, that occur during the operation when the amount of drugs in the body is high. The other is chronic effects from drug residues that remain in the body for years. Antibiotics are another very toxic class of drugs that are used liberally after many types of surgery.
