Prostatitis does not usually cause calf muscle soreness; calf muscle soreness may be associated with excessive exercise, localized muscle inflammation, and so on. Prostatitis can be caused by pathogen infection or non-infectious factors, and typical symptoms include frequent urination, urinary urgency, and painful urination. Locally, there may be hidden pain in the perineum and lower abdomen, which may be accompanied by soreness in the lumbosacral and inguinal areas. It usually does not involve the calves, resulting in sore calf muscles. In general, the most common cause of calf muscle soreness is over-exercise, which can be relieved by proper rest. Localized inflammatory diseases such as localized myofasciitis and salpingitis (an acute infectious disease in which the skin is seen to be red as if painted) can also cause the symptoms.
