Have you had your testosterone level checked? You really need to do that to find out what’s going on with it. That is probably the reason you’re having this problem, but It is very unusual for someone to have a three month shot and never had their testosterone come back too close to normal.. You don’t mention your age that could be a factor if you are in your 80s or late 70s.

When I had really bad hot flashes I had depo-provera Shots every three months and that stopped them. Oxybutynin i’ve been real good for some people to stop the hot flashes.
