I am Tai Chi Master Karol, 65 yrs. young. I have never had any internal problems of any kind...only injuries in motorcycle accident at 16. I was the youngest licensed acupuncturist in US in 1976, herbologist and nutritionist. Today at around 10am pst after drinking a quart of freshly made watermelon juice, a daily routine, I noticed I had leaked fluid on my pj bottoms and saw what at first I thought was blood on my pj s and then upon closer exam I saw a drop of blood at penus opening! Being an expert on meridian energy cycles and cleansing phenomena, I thought that the Juice I had consumed ten minutes before discovery...had caused a cleansing action of some kind with my kidneys via bladder. I was able to urinate a normal pale yellow color and the bleeding had stopped. I rested on back after drinking a glass of water to help continue any flushing of my kidney-bladder system and after another couple of hours need to urinate again and had no problem. I felt an urge to defficate and it was a combination of stool and small diarrhea discharge, followed by a small discharge (teaspoon) of blood from end of penis and then normal urination followed. I continued to rest through afternoon to about 3 p.m. and for the following hour and a half still felt fine. Actually I was feeling great all day except for the anxiety of what was happening... And then around 5pm...which is the time of the day for the kidney and bladder Chi to activate the late afternoon pee...and again I found a little more blood in the urination in the first moments of peeing...followed by normal urination to completion. Now the winter time of the year is considered the time of nature s cleansing for the kidney and bladder organs in Chinese medicine tradition... And so I hope I am having a cleansing action in my body...but of course I wonder what other medical view of these symtoms may imply...and so as I have always been my own healthcare provider...I thought to go online to see what advice a doctor would advice giving the events I have described above. Thank you for your reply.
