Thermofor (hot water bottle) application to painful areas
Czerniak points out that heat therapy was standard in his grandmother's era and works on the same principle as anti-spasmodic drugs – muscle relaxation. He stresses that chronic contracture is caused by acidosis from poor circulation, and heat opens vessels, delivering oxygen and removing waste. However, he warns of a paradoxical 'rebound' pain: like freezing hands that become agonizing when warmed too quickly, the acid-flushed area can suddenly hurt due to cathepsin enzymes if the re-warming is too abrupt. Hence he advises gradual warming.
Heat locally promotes vasodilation, increasing blood flow, which washes out lactic acid and inflammatory mediators, reduces muscle spasm, and breaks the cycle of hypoxia-acidosis-contracture.
He mentions that you may see skin changes after using a thermofor on the back, which are harmless but may persist longer over the sacrum.
