What does testicular pain mean?

I was 17 when I took a single pill of 1.25mg fin with high testosterone. I then had 5 days of pain in my left testicle and have been going through hell since. My testosterone apparently had risen by 62% to 39NMOL from 24nmol in July, 3 months afterwards. How common is this actually, why and in whom does it occur and what does it entail for those who get it? Is it a precursor to PFS?

Had testicular pain for a month, have zero now though, my hormones seem to have stabilized, but body and brain slightly damaged it seems, the precursor of certain side-effects doesn’t have a specific meaning i’d say. I still get nerve shock pain in my genitals and elsewhere in my body.

I’ve got an increase in hair growth, including beard, hair eye lashes, and body - Haven’t checked my hormones since last.

I got acute testicular pain when I took a large dose of steroids, I thought pain meant the testicles are shrinking or that damage is occurring.
