hello, my brother has experienced pain in the testicles and surrounding groin muscles for multiple years, this pain is usually aggravated when sitting for long periods of time, and is increased with stress. he has had mri s and injections with no positive results, he has been seen by 2 separate urologists with no success. he recently has been seeing a holistic doctor that has made some muscle and nerve manipulations in his nerve posterior to his testicles which has given him huge relief but it has only been temporary. suggestions?
