How are you?
Testicle pain is discomfort in one or both testicles. The pain sometimes radiates to the lower abdomen. Testicular pain can be due to injury, infection (Epididymitis or Orchitis) or inflammation, testicular torsion -- most common in young men between 10 and 20 years old, excessive bicycle riding, hernia or kidney or ureteric stones.
You can provide support to the scrotum by wearing an athletic supporter, apply ice to the scrotum, take warm baths if there are signs of inflammation, while lying down, place a rolled towel under your scrotum or try over-the-counter pain relievers, like acetaminophen or ibuprofen.
The presence of blood in the semen (ejaculate) is also called hematospermia. Blood in semen can be caused by many conditions affecting the male genitourinary system. These include infections like herpes,Chlamydia,cytomegalovirus,trichominiasis ; inflammation of the prostate (prostatitis), epididymis (epididymitis), or urethra (urethritis) ; calculi (stones )in the seminal vesicles or prostate ; polyps in the urethra ; ejaculation-duct obstructions ; cysts, hemorrhage, or other abnormalities in the seminal vesicles ; benign or malignant tumors of the prostate, bladder, testes, or seminal vesicles and metastatic cancers.
All thesse conditions can be diagnosed by physical examination and investigations like urinalysis,semen analysis and ultrasound and MRI.Treatment will depend on the diagnosis.So pls consult a urologist and get yourself evaluated.
