Dear Mates ,
My name is Dr. Mircea Anghel and i'm from Romania working at The Colentina Hospital and also i have been studying this problem for years. I had recently discovered a cure.I can't guarantee that the cure will totally make it go away but you should try it.
First of all , you have to take a bath (with cold water + salt). Try rubbing the testicle with a sponge filled with vinegar. After that , the skin will be soft and tidy. Then , you'll have to buy from the Drug Store (i don't know the names of your drugs from your country) something that contains DICLOFENAC. You will have to massage the area. Doing this twice a day for two months will cure your problem.
Hope this method helped you.
[The acid from the vinegar will enter through the sking because of the salt and it will help your nerves to heal.The diclofenac won't let the skin inflamate.
Regards , Dr. Mircea
