All day heat
I stumbled on this thread Huge success with the basic treaments!! - Peyronies Society Forums , it’s also discussed here Heat Packs - Peyronies Society Forums .
All day heat with hands warmers , an elastic hair tie or a velcro wrap.
Then one could add a soaked cloth underneath to benefit from moist heat. Any strip of cloth should do as the heat pack is maintained against the shaft by the hair tie or velcro wrap.
With the benefits of heat in PE already discussed ,the prospect of wearing those for hours before PE sessions is extremely tempting. They should be very beneficial for scar tissue too.
