Every case is different so I guess it makes things difficult.
I had a small and sore lump come up at the top of each testicle.
I went to my local doctor who told me it was a common thing, just a small cyst, he then sent me for an ultrasound which showed I did have a cyst, from there my doc sent me to our local hospital, he said they may drain them and all would be OK.
At the hospital the surgeon had a good feel of them and said come back in a few years when they are big enough to work on (the cysts that is), I asked him roughly how long that would be, he said maybe 10 years, now 5 years later the pain has stopped (it did after the ultrasound) the cysts are still there but have not grown.
I think the pain was caused because I thought I had testicular cancer or something, keep feeling my testicles to see if the lumps had grown, as soon as I found out what it was I left them alone and the pain vanished, to date it has never come back.
By the way the lumps were the shape and size of a grain of rice, right on top of each testicle, no it isnt caused by masturbation, funny most things that go wrong with the male genitals seems to be blamed on masturbation, I guess we all must feel guilty or something.
i think you are doing all you can really , its been checked by a doc and treated , my hb had same thing and he never got refered and still has lump 5 years later so i dont think its much to worry about . x x
