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.
Spinal anesthesia is slightly different to an epidural in that a smaller needle is used to inject a local anesthetic drug into the spinal fluid. Spinal anesthesia is often used for emergency cesarians as the result is immediate pain relief and loss of sensation.
