Hello, I'm really starting to worry. Several years ago I was lying down on my left side and as I rub my right buttocks cheek I felt a golf ball size lump. I went to the Doctor and he said it was a mass of fat, harmless. Now, this mass has grown as wide as 8 inches and traveled down by my lower buttocks. It is noticeable and my right side (buttocks cheek,hips, leg) are larger than my left side. It's not only painful when I press deeply it's embarrassing. My right leg and knee hurts at times. I've never had any cosmectic work done nor liposuction. To note I'm a curvy women that was proud of my large buttocks, now I have one extra large cheek and the other( left cheek) is getting flat! Please help!
