Don't do the surgery! The cream and stretching can help. But people i know who have had the surgery done and one of them even done it himself (God knows how) have said they have regretted it. Be patience, cream, stretching... it should be ok. Make sure it's the cream from pharmacy and not over the counter.
Still happens. Happened few years ago to a Singh from Brum where the Panj made him crawl into divaan during Rehansbhai. They stopped the Kirtan, he had to ask for maaphi from sangat. Those from the Midlands know this.
one of my sons had this problem as a child and it was resolved with homeopathy and didn't need the surgery , try to locate a practioner near you it may save you the discomfort and possible post operational numbness .
