I noticed a lump on my lower right rib cage about a week ago, I checked my other ribs but did not find any lumps. I didn’t think much of it and thought it might just be a lipoma. ober the last few days several more lumps have formed on both the right and left, all different sizes.Some are long and about the width of the rib and some are more circular. Should I go to the doctor as soon as possible to have them checked out. It just worries me since at least 4 have appeared in the last week.
