Hello, My husband is 24 years old and is experiencing tenderness/pain in his lower back(mainly the left side).He has also these bumps below that about 3 small(size of a toddler fist) in his back. He also has one on the right side of his hip and left leg. I don t know if these bumps are connected to the lower back pain as he has had the bumps on the back looked at before and was told they were swollen lymph nodes and not to worry too much. Now about 2 1/2 years later they have grown a few cm in size and are appearing on other parts of his body along with 3 1/2 weeks of lower back pain/tenderness.
