Hello Rb26dett,
I am sorry this is happening to you. Keep fighting please!
I have taken 2 pills of finasteride and I had for almost 3 years the genital issues, and the muscular/joints issues. I am not cured yet but i feel really better and what really makes a difference for me is : no sports, no masturbation/look at porn, a multivitamin(from nutri&co), a diet where I eat a raw garlic clove cut in small pieces in the morning (very important), vegetables/green lunch with onions, nuts…, and in the evening a normal meal. No drugs, alcohol etc.
I dont take anything else and so far i think my body is readapting itself. I also had these brain fog, these difficulty to remember things etc, I know it is hard to follow habits and feel crappy but please think about these options, they are not invasive and could help you get better.
