I know it’s difficult to be persistent but try and get the actual blood work off your doctors. You are so young - this could be the start of quite a journey for you so any record of what your hormones are like at certain times could be very useful. Plus it’s very common for doctor’s to say that blood test results are ‘in range’ when often they are not. It is crazy how finasteride, even at high dosages such as 5 mg can cause persistent problems. I find it difficult to accept that a few months on and of got me.
Hang in there man. Have you told your parents about what’s going on?
