Small lump on my left testicle

I found a small lump on my left testicle a few days ago. I have been to see my GP today and he has diagnosed it as an epididymal cyst. He told me it's a lump in the epididymis not the testis itself.

My concern is that I'm not sure he has felt the lump correctly. It is hard to find unless the testicles are warm (during a shower for example) Hard to find, especially in a cool doctor's room.

The small lump feels solid to touch - certainly not soft - and similar to a grain of sand in size. Would an epididymal cyst feel hard to the touch? From what I’ve read they should be soft to the touch. I can only run my finger over the lump – it’s not possible to feel between two fingers. I can feel all the cords joining the testis and the lump feels to be near that join but more on the testis itself - top left.

On my right testicle I can find another lump but this one is at the back. This one is much smaller and when checking it feels hard too. This one is where the tubes join the testis and does feel that it’s not attached to the testis itself. My question is this... Is it definitely an epydidymal cyst and as such nothing to worry about could it be that the doctor hasn't felt it correctly and it is a lump on the testes then that needs to be looked at. Further info much appreciated.
