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.
This type of anesthesia is generally used for minor surgeries (e.g., breast biopsies, vasectomies) and to stitch small wounds. It is usually administered by injection, which can be painful. However, the discomfort only lasts for a brief moment, and the anesthesia usually takes effect very quickly.
