I Have An Intermittent Feeling In My Right Testicle That

I have an intermittent feeling in my right testicle that creates a feeling of intense heat. This occurs 10-12 times a day, sometimes more often and it happens in various situations. Sitting, walking, laying down etc. It is not painful, there are no external signs, there has not been any trauma to the area. The "heat" lasts for approx. 20-30 seconds and goes away. It is isolated only to the right side. I have a history of colon cancer (2011-2012)
