Gyno caused by finasteride?

Been using finasteride 0,1% topical solution for about 1 month now and got a burning sensation/ muscle ache in my chest a week ago. Niples aren’t really sensitive but my shirt going over my chest does feel a bit sensitive. Chest don’t show anything so no pictures attached.

Is there any possibility that this can be gyno? I want to ask my GP for blood work on my estrogen levels which may be higher due to lower DHT.

Should I stop using finasteride?

Yeah, it could be early gyno. Even topical finasteride can lower DHT enough to mess with your hormone balance, leading to more estrogen. Burning or chest sensitivity is a common early sign, even without lumps. Ask your GP for bloodwork: estradiol, DHT, and testosterone

Estradiol was very low. They didn’t test testosterone, is that fine?

I would check total and free testosterone and dht as well
