Hi. I woke up one day and felt pain on both sides of my rib cages l, touched them and felt big hard lumps on each side top and bottom . This was about 4 months ago. I went to my doctor who looked and saw that they were red, but said he saw no evidence of a inset bite. He told me it s probably choronistis and would probably go away on its on. I took x-rays and that came out fine. When I walk with my arms down, it almost feels like I have something sticking out of my ribs touching my arms. I m 6ft 330 pound. He said I need to lose weight. Could weight be the cause of this?
