Your problems are very mild, and you’ve been in this situation for less than 2 months, some of us here have full-on PFS for more than 10 years. Your chances of a timely recovery is very high since you only used it once, you just need to be patient. People who try drugs and supplements to cure themselves usually end up worse.
Nowadays there seems to be a trend of one time finasteride users with very mild symptoms who come here totally panicked and expecting an immediate solution. I think it’s psychological for the majority of these people. In any case, there is no known cure for PFS, and this forum is about sharing ideas and experiences.
At this point seeing a doctor who knows about this condition would be a lot more helpful for you than spending your time here.
