Varicocele or No Varicocele? Serious?

On 15/11, I had visited a CSW. Post that, due to anxiety, I took - HIV PEP for 10 days, Doxy, Azee 1gm single dose, Cefixime 400mg single dose, Ceftriaxone 500mg IM shot and Cefixime 200mg, Fluconazole, Itraconazole all between 16th November to 4th December. On 16/12, I did a USG Color Doppler with cough test only in supine position and doctor said I have a small left varicocele - 2.2 mms at rest and 3.0 mms at Valsalvas. On 19/12, I did a testosterone Total test and result was 795. On 19/12, I did a USG Color Doppler again from another centre, doctor examined me in sleeping and standing position (I did not put a lot of pressure when he asked me to, I barely put any pressure) and said I have NO VARICOCELE. Prior to 15/11, I have never had any symptoms. I did long distance running and always felt my left testicle was the healthy testicle. My testosterone free test result was 39.7 pg/ml. Have I developed a varicocele after 15/11/2025? Do I have low testosterone? Is my varicocele serious?
