Hot Water and Pressure to Reduce a Keloid?

Keloids should be treated early and aggressively.  Pressure treatment is recommended using specific protocols, however, hot water may elicit a histamine response that has not shown to modulate keloids. Surgery90210 Karamanoukian

If you have a developing keloid, there are many different ways to treat it.  I have never heard of hot water.  Some treatments include steroid injections, topical silicone sheeting, pressure dressings,. surgical excision, and radiation to name a few.

There are many ineffective and partially effective treatments for Keloids. There NO uniformly completely effective Keloid treatments.
If your scar is indeed a keloid, I would see a Dermatologist or a Plastic surgeon who may want to inject it with corticosteroids / possible radiate it and treat it with silicone sheeting and pressure.
