Its not likely its a coincidence at all as testicle pain is one of the most common side effects from finasteride. I restarted topical finasteride and used it only twice and already got slight ball pain and I know for sure its not coincidence, because I never had it on its own. There is no question finasteride causes nasty sides which might be different in everyone. This guy is asking for a similar expirience to decide how others dealt with it.
Anybody who knows how the testicles, prostate and penis are connected has an idea about how things really work and how a drug that directly affects the prostate could have an impact on them.
Nobody who takes these drugs for a cosmetic reason would ever admit or accept that it could do damage, especially when it's so promoted and sold as a sugar pill at the drugstore, especially in the US... Let them be, most of them will learn it the hard way, the rest will just accept it or think that it's from any other reasons except the drugs they are taking...
What i have learned the most from lurking these hairloss forums for a while now is that you can't trust sh*t from the users "mouths", 99% of them are so frustrated and emotionally affected by hairloss that they live in a completely different reality compared to people that are not that affected by it, or like people who don't have this problem. And i understand them until a point, the point being when their refusal of reality and facts damages others, they don't actually give a sh*t and refuse or ignore anything that could threaten their only possibility in keeping or regaining their hair.
It is what it is and that's why you should trust nobody, you should do your own research and take decisions based on that, all the information is available for everybody not only for them and it's not like they actually could know something that others don't. In the end you have to realize that all the information around the internet is made by doctors, scientists, pharmaceutical companies, the medical industry and so on, these retards, most of them just read it, rip out of context what suits their mindsets and frustrations and after spread it like an absolute truth all over the place regardless of the damage they could do.
Only by saying "coincidence" his mind found peace and reassurance that it is really a coincidence and that it really can't happen whatever anybody else says. He does not know the user, his medical history, life or whatever but he strongly knows that it's just a coincidence, it can't be finasteride, "my only hope in keeping my hair", it's not written on the leaflet, there are not many studies on it and first of all, it didn't happen to me, yet, so it can't be real.
