My tight foreskin was cured by a balloon device. My GP recommended it, as I was not able to afford an operation and I did not want to loose my foreskin, if I could avoid so.
The Company that sells the device is big on promoting gentle foreskin stretching and has a web site. They are based in Sydney Australia and have a good reputation.
I found that most of the tight foreskin searches came back with SPAM or junk. This Company had a good web site with lots iof information and I liked their customer service as well.
The best thing to do if you can't afford and operation or don't want one, is to try this neet little balloon stretcher, it worked for me. I could not find any other company promoting this product and it seems they manufacture the product in Australia. The company also claims to their product listed on the Australian Government Medical Device Register for use in Phimosis
I think it cost me $99 or around 50-60 GBP, i know it was cheap compared to $3000 the urologist
quoted all up to have surgery. For me this was a very good deal.
