I am 52, 6 feet tall and weigh 160 pounds. I am very active physically for recreation, either walking or cycling. I cycle more in the summer and about a month ago I noticed nonspecific discomfort in the area between my penis and anus while out cycling immediately after having a double espresso...an unusual dosage of caffeine for me. I am a physiotherapy (orthopedics) lecturer who has not practiced in almost 20 years. I have palpated the area and found no specific areas of tenderness or swelling though I have varicosities in my scrotum of long standing. I had the prostate blood test this spring and it was negative and this was the second negative test in the past 4 years. I have also had 2 colonoscopies in the last 15 years, both negative. The discomfort has been consistently mild and can be brought on with a full bladder and prolonged sitting (I just sat in a car for 18 hours over the last 2 days). The best way to describe the symptoms is what I have always referred to as blue balls though orgasm has not relieved this problem. Please advise. Thanks.
