Experiencing Side Effects 3 Days into Topical Fin; Long-term Topical Min User Seeking Advice on Dosage

I started topical fin 3 days ago. 0.025% topical in a 1ml solution with min which i use x1 a day. ( if it do it x2 does that mean 0.05% daily (0.5mg))

Either way, im getting some dull ache pain in my testicles but im 99% sure its just a nocebo. Can i have some cope, because 1) its topical 2) its a TINY -amount

Ive been on topical Min now for 7 months + havent rlly seen any improvement so decided to start fin but ive been really anxious

Surely its just a nocebo?

Another question. If i took the 0.1ml amount x2 1ml thats 2mg? So why do ppl take more?
