I know there is a potential for some ridiculous responses with this thread, but regardless I felt like posting my recent experience. I figured some of you may have experienced the same issue or something similar (or know someone who has). I can't remember exactly for how long now, but I've been using a laptop computer at home in a similar fashion for many years. Especially at night before bed. Often times I'll lie in bed and read articles or browse sites while lying in bed. I don't place the laptop in my lap but I do tend to keep it directly in front of me (not touching my body) or to my side (ditto not touching my body). If I had to guess, I'd say I've been doing this for the last 5 years. Before that, I didn't have a laptop as I used my desktop for my computing needs at home. About six months ago I started to get this very strange pain in my right testicle while using my laptop in his manner. I did not feel this pain while using my desktop at home or at work. The pain would be best described as an "aching" or "squeezing" around the testicle. It also created a "tingling" sensation at times. This pain would also occur directly below my testicle in the area where the leg and crotch met (groin?). I freaked out that it might be testicular cancer, so I went to a Urologist who did an exam and then had me get an MRI of that area. Luckily for me I didn't have cancer, but he did detect swelling in the right testicle, and put me on a medication. A week later I felt better (and avoided my laptop during this time). He officially diagnosed it as Epididymitis. Even though I wasn't sexually active at that time, I was getting out of a relationship a year prior where I never used condoms, so it could potentially be from that, but he wasn't entirely sure. I told him about the laptop, thinking it might be connected, but he had no idea if that was the case. I reverted back to my laptop in the bed ways, thinking the Epididymitis was the culprit and it wasn't related to the laptop. Sure enough within minutes of using my laptop in bed, the exact same pains/sensations returned in the same areas. I should also state that these pains never occurred at any other time other than the laptop use in bed. After two or three more occurrences that week, I stopped using my laptop in bed and the pain has since never returned. I should also say that I once used the laptop in bed with a pillow resting below the laptop, and the pain still returned amazingly. I have now refrained entirely from using the laptop unless there is a desk of some sort to place the laptop on. The pain, thankfully, has never returned using the laptop in this manner. Onilne research showed me that others on different forums have had a similar experience to mine. However often times those men are placing the laptop directly on their laps, and I never did that myself. It was always placed in front of me or to the side, resting on the bed itself. The research on laptops and testicular cancer/pain seems to be pretty inconclusive at this point. However given my experience I'm convinced that it is dangerous to some regard if you are placing your laptop that close to your body. I now use my iPhone in bed if I need to browse the web, and have contemplated using an iPad to do the same, however I worry this might also trigger similar symptoms (who really knows if that would be the case). Has anyone here had a similar experience or know somebody who has?
