Pain in Left Testicle while on Finasteride

Is this a common symptom because of finasteride? It also aches a lot when I lift heavy in the gym, especially when doing squats. My left testicle also got bigger than my right testicle, is this normal? My right testicle doesn’t ache at all, only left.

Pain in a testicle can be from many causes, and if it is swollen it would worry me even more. You should see a doctor as some of the causes can be threatening to the testicle.
