Subject: Left testical is little bit swallen and painful, pain goes deep inside after using "Keflex 500, Nexium 40 mg, Metamucil

More: Male, 47, Healthy, non smoker

Couple years ago it happened again. I have used "Bactrim Forte" for my teeth, afterwards painful - sensitive testicals for 3 weeks. The prof. Specialist, after all those tests couldn't find anything but Bactrim allergy probably.
This time, my GP gave me Keflex 500, for minor infected testicals.
But I used Nexium 40 for my stomach, and Metamucil for my IBS.
I have especially left testical problem now. As I learned from internet that those drugs can affect each other.
My left testical is quite lower than the other, my functions are normal but pain in the ledt testical sometimes does deep inside towards prostate area.

I want to learn, this could be the similar drug allergy and goes itself in couple weeks?

Thanks in advance
