Aching manboobs and inbetween armpits and chest

Minsan both sa ilalim ng nipples pero di mismo sa nipples, at noon ay on and off ang pangingirot inbetween armpit and chest ko. Madalas left and minsan sa right.

I also have hashimoto's hypothyroidism and would like to ask and confirm if may ikinalaman kaya yun sa mga nararamdaman ko dito?
