Hi I’m a long time lurker on the forum due to health anxiety issues however this is my first ever thread.

Found a lump and I’m freaking out!

Ok so, last week I noticed some pain in my testicles. I went to the er and the doctor was pretty sure it was an inflamed epididymis and put me on some antibiotics for 2 weeks. So now with 1 week left the pain has subsided quite a lot which is nice. However this evening I noticed a small lump on the top of my testicle. It’s located on the top half of the testicle. The lump feels a bit weird like it’s not spherical, it’s kinda thin and long of that makes sense. Like a little worm. It’s pretty hard. Now I’m freaking out about testicular cancer. Could it be anything else? Should I wait calling the doctor until I’m finished with my antibiotics next week?
