Hello I Have Recently Went To The Doctor To Find

Hello I have recently went to the doctor to find out why I had a slight pain from my left testicle to my lower abdomen. I found out I have a hernia but they also said I had a bacteria infection but the antibiotics only worked while I was on them (didn't have reoccurring symptoms until towards the end of meds) I take my last pill tonight and it just began to hurt again. And I noticed and tiny tiny little bump attached to my left nut which used to be kinda in my veins I guess you would say in my sack. But I have no idea why and it actually is only really painful when I touch it or feel the spot. I do have a slight sensation of pain from there to my lower abdomen standing up but when lying down it isn't so bad. Like not even there, but I was told this has nothing to do with my hernia and was put on antibiotics and they were helping until I finished them.
