You guys can relax, the donut may be uncomfortable and look odd but it’s not going to hurt you.
I have had many uncomfortable donuts that wouldn’t even allow me to retract my foreskin to take a piss. A few remedies I have come across for this are edging it the donut isn’t too prominent, soaking your member in ice water for a minute at a time cycling warmth and cold, and wrapping your erection starting from behind the head (foreskin over the head) to mid or head down to base. Obviously you do not want to wrap too tightly or with anything sticky that can be painful pulling off, ace bandages or tennis rack tape work well for this and after which you will see some decrease in the donut but nothing significant.
I tend to think of the lymph build up as the inflammatory response in muscles. “Inflammation is a protective attempt by the organism to remove the injurious stimuli and to initiate the healing process.”-Wiki. Although, inflammation is part of the body’s healing process this can come with a continuous pain and heat at more blood is rushed in inflating the injury like a balloon both damaging and attempting to heal the area at the same time.
As anyone who with a chronic sports injury can vouch cold therapy helps fight this and once swelling has subsided heat applied to the area helps recirculation and recovery. I have one theory I have been working on that the penis heals faster when the donut shape is gone and healing may be faster. So far I have been experimenting with heat and cold therapy for almost a month with positive results though I doubt many guys would go to those uncomfortable extremes for results. Let me know what you guys think.
