I am a 48 year old. I was never sick, I never go to a doctor. I do not take medications. I have worked out for 30 years five times a week. Nothing real heavy these days (treadmill three times a week - fast walking). Symptoms started about a month ago with intermittent dull stomach pain and mostly on the left side. It progressed to dull testicle pain - again mostly on the left side. It is usually not stomach and testicle at the same time. There are no noticeable lumps in the testicles - both feel the same to me, but the pain is more on the upper top of the testicle from what I can tell. I believe there are some tubes or cords there naturally and to me, it feels like the left side does feel more cordy (for lack of a better word). I have occasional groin tightness.
Symptoms I do not have:Any masses or lumps.No tiredness/fatigue.No bulges anywhere so I do not think it can be a hernia (I do not remember feeling anything).No pain urinating and no blood in urine or feces.No lower back pain but an occasional stab in my mid back (probably referred pain?). My main symptom these days is the dull testicle pain on the left side upper top. Sometimes, I do not have any symptoms at all and almost never when I am working out. But for a month now, I know it is there and it is annoying and the last two days, I feel like the dull pain is slightly greater at times in the left testicle. Again, I am not one to run to the doctor. Anything, I have ever had has gone away if I gave it time. The pain/discomfort is not that great but it has been at least a month. After doing a tonne of research on the internet, I have seen so many conditions where my symptoms fit but none that pinpoint just a few symptoms I mentioned. Sorry for the long winded query but what are your initial thoughts? And do you have any follow up questions for me? Thanks.
