Hello...I Had Taken An "Over The Counter" Testosterone Booster For

Hello...I had taken an "Over the Counter" Testosterone booster for about a month and noticed my testicles had enlarged...i immediately stopped taking the pills but the condition remains...they are NOT sore to the touch, there is NO redness, i do not seem to have an infection that i can tell, i urinate normally when i go with NO pain or itching...I am 70-years young and am in pretty fair health i think...i am on blood pressure medication (linsinopril) and my BP usually is about 125/75-ish... And yes, i have ED and my Doc has given me Viagra which helps....any ideas?? Thanks in advance!!
