i have bumps all over my body on the arms and stomach areas probably about 20 or more on my stomach one of them is about 3 inches long and 2 inches wide and is very pronounced. the othere ones range from small to the size of a half dollar. when a new one appears it causes discomfort until it starts to be noticable then no pain the largest one on my stomach seems to be getting larger over the years. i had 4 taken out about 20 years ago and was told they were fat tumors. any idea what causes them or is there a way to make them shrink. they dont hurt to push on them but its embarrassing to me to see them any ideas
