hi read your query this sounds like varicocoele read on the answer for details Varicocele occurs when the network of veins that leave the testis becomes elongated and enlarged. Normally, veins allow the blood to flow away from the testicle - if there is something wrong with them, blood builds up in the testes. Varicoceles can lower a man s sperm count and undermine the quality of his sperm. In some cases, the testicles may shrink. It is common for the patient to experience no signs or symptoms at all. In some cases there may be pain, which can.. ..be dull or sharp. There may be a sensation of heaviness. Some describe it as a dragging-like pain. ..worsen when the patient is physically exerting himself, standing or sitting. Prolonged periods of exertion are more likely to bring on pain. ..get worse later on during the day ..feel better when the patient is lying down Eventually most varicoceles grow and the person becomes more aware of them. Often described as feeling like a bag of worms . During a physical exam a doc may be able to feel the mass of veins, or the bag of worms. If the doctor is not sure, a scrotal ultrasound may be ordered, this will show whether the veins in the pampiniform plexus are greater than 2mm. so i would suggest you get the ultrasound to confirm the diagnosis best of luck
