I have a "warmness" feeling on the lower left side of my abdominal area. It actually feels like it's coming from the inside-out. It's not a burning sensation and it's not painful. It's just warm. When it first happened I thought I might have been leaning up against something else warm, but obviously I wasn't. This warmness occurs a few times a day. I don't notice it in regards to time of day or when I eat.

I'm a 36 year old female. I workout on a regular basis. I'm 5'4 and weigh 155. I eat healthy. I thought I had an ulcer a year ago and my doctor prescribed something at that time. Since the symptoms of an ulcer went away I stopped taking the medication. Is this related to an ulcer? Are my female organs on that side of the body?

Any help or comments are appreciated.
