Myxedema

                      Testicle pain, or testicular pain, is pain that occurs in or around one or both testicles. Sometimes testicle pain actually originates from somewhere else in the groin or abdomen, and is felt in one or both testicles (referred pain). The scrotum or testicle is not swollen, but there is a dull, throbbing pain or discomfort on one side that may become worse during the day. In severe cases, even the touch of clothing or bedclothes makes it worse.
This is a common problem, and there are many possible causes, including an infection. Pain in the scrotum can occur after a vasectomy; no-one understands why this happens, but it seems to affect up to 6% of men who have had a vasectomy.

Causes 
☞ Diabetic Neuropathy (nerve damage caused by diabetes)
☞ Epididymitis (testicle inflammation)
☞ Gangrene (specifically, a type of gangrene called Fournier's gangrene)
☞ Henoch-Schonlein purpura (blood vessel inflammation)
☞ Hydrocele (fluid buildup that causes swelling of the scrotum)
☞ Idiopathic testicular pain (unknown cause)
☞ Inguinal hernia
☞ Kidney Stones
☞ Mumps
☞ Orchitis (inflamed testicle)
☞ Retractile testicle (a testicle that pulls up inside the groin — this condition occurs in young boys)
☞ Scrotal masses
☞ Spermatocele (fluid buildup in the testicle)
☞ Testicle injury or blow to the testicles
☞ Testicular cancer
☞ Testicular torsion (twisted testicle)
☞ Undescended testicle (also called cryptorchidism)
☞ Urinary Tract Infection (UTI)
☞ Varicocele (enlarged veins in the scrotum)
☞ Vasectomy

Treatment 
1. Antibiotics to treat infection
2. Surgery to untwist testicles (in the case of testicular torsion)
3. Pain medications
4. Surgery to reduce fluid accumulation in the testicles.

Complications
Your doctor can successfully treat most cases of testicle pain. An untreated infection such as chlamydia or a serious condition such as testicular torsion may result in permanent damage to the testicles and scrotum. Damage may impact fertility and reproduction. Testicular torsion that results in gangrene can cause a life-threatening infection that can spread throughout the body.

Prevention 
Not all cases of testicle pain can be prevented. However, there are some steps you can take to reduce the underlying causes of this pain. These steps include:
1. wearing an athletic supporter to prevent injury to the testicles
2. practicing safe sex, including using a condom during intercourse
3. examining your testicles once a month to note changes or lumps
4. preventing urinary tract infections (UTIs) by emptying your bladder completely when you urinate
