Hi, I am 34 year old married man. I feel heat/burning sensation in my testicles while sitting for 2 hours or more, especially while driving. I thought it is due to underwear and I stopped wearing underwear too but still.I am feeling same heated feeling when I sit for two hours or more. I feel relax only when I start walking but when I sit,it start again after 5 minutes. During this condition I want to put ice on testicles so that I can be relaxed. Its not pain, but it feel like extreme heat even though if I touch my testicles during this condition, I find them mild cold in stead of warm. I am out of country and I have not been involved in sexual activity for last six months.Please guide me how can I cure my problem and also explain if it is very serious disease?Thanks
