I have these bumps on my shins that hurt very

Patient: I have these bumps on my shins that hurt very bad when I try to run. I do have shin splints but now I’m getting better in shape my shin splints have went away. I have several on both tibias. I had ultrasounds done and they had blood running through these bumps also I have xrays done on both lower legs. Everything came back normal. I can’t remember what they called it. I want to be a runner so bad but these bumps are holding me back. What are they and how can I fix it?
