Dull pain right testacle , no blood in pee, not severe pain, so no torsion ? no lumps or bumps eiter ? can i take pain relievers?

Diagnosis first: Before we start talking about pain relievers beyond just Tylenol (acetaminophen) or an anti-inflammatory we need a diagnosis. Either you have become an Internet researcher or your MD told you, that torsion is unlikely. However, if you have only seen your PCP, I would recommend a thorough Urological evaluation. You should not have dull pain there on your own short of delayed ejaculation and should be seen/imaged.
