Shortly after joining a boot camp style group exercise class (very intense exercise), I noticed that for two days, the color of my excrement was black. I did not worry since I had experienced this in the past shortly after doing intense exercise. This lasted for two days and then came a bout of diarrhea that lasted a week and a half. During this period, I was experiencing a lot of pain (very intense burning sensation) while going to the toilet. I went to the doctor and he checked and informed me that it was an external hemorrhoid which was healing. After applying Aquaphor ointment per his instructions, the issue went away within two days. After feeling normal for the most part for around four days, I went back to the intense exercise class. About three days after that, I started to feel the symptoms that I'm currently feeling which include itchy anal area, pressure in anal area which occurs mostly at night, itchiness underneath testicles, raw sensation around the ring of my penis head and painful when ejaculating. I was advised to see a gastroenterologist since the biggest symptoms were related to the rectal area and the pain at night was very worrisome. Currently trying different remedies which only bring temporary relief. Lotrimin for itchiness around penis/testicle area, aquaphor ointment, and preparation h. There is no visible rash though the itchiness is there in both the testicle area and anal area.
