I have mild pain in my left testicle and a small lump in my scrotum. What could it be?

Hi doctor,

I am a 44-year-old male who is 6.2 feet tall and weighs about 180pounds with an athletic body. I like to do physical activities to keep fit and take a balanced diet. I am having mild pain for the past three weeks in my left testicle. Sometimes it subsides for short intervals. However, after some physical activity, it tends to go up slightly. I have not taken any painkillers. There is no urologist within two hours of my place of residence. I examined the testicle on my own after seeing it on the internet. There is no visible swelling, lump, or redness on my testicle to the best of my understanding. However, the left testicle appears tender to touch, and on one specific point, the pain is there to touch. It also occurs more significant than the right one and is above the right one's level. The scrotum, a lot of times, feels tight and heavy. There is no urology related problem with my parents. I have a problem with having too many noncancerous lumps in many places in the body, which increase with age, especially on the arms. I have a few on them again in my body near the abdomen, arm, and side back. Now I feel such a small lump in my scrotum also near the groin. I got two ultrasound done for a similar thing two-three years ago while consulting a physician. They could not diagnose anything. The pain subsided on its own then. However, now this has recurred. I also have a problem requiring to urinate soon after drinking water (I tend to drink less water because of less thirst while I want to drink more). Also, my urine stream has gone relatively weaker in the last three years. Also, I feel that my bladder does not hold that much urine as others can for as long as I can remember. If I drink a glass of water at night, I get up at least twice to urinate. I have tried to explain all I could as regards my problem. Can you suggest some relief from the pain? I can avail urologist facility only when consultant urologist starts visiting my place. All other vitals are normal except for an occasional high pulse around 90 to 100.

Thanks and regards.
