Conversion heating - This involves the conversion of one energy form (eg, light, sound) into another (heat). Superficial heat is produced by heat lamps or radiant light bakers, with heat being transferred when the conveying medium (light energy) is converted to heat energy at the skin surface.
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.
Local anesthesia is often used for minor surgeries and outpatient procedures (when patients come in for an operation and can go home that same day). If you are having surgery in a clinic or doctor's office (such as the dentist or dermatologist), this is probably the type of anesthetic that will be used.
