So I'm 15 and I train for triple jump very regularly. About 5 months ago I was jumping and I felt some sheer pains in my right shin - and so I gave it a weeks rest. Within that week I seemed to feel okay and when I got back into training I would not feel any pain until I progressed further through the training session. From there I just carried on training and tried to ignore the pain but it worsened so I went to a doctor - he thought it was shin splints so I gave it 2 weeks off but the pain came back. I got an x-ray and everything seemed to be okay. Then from December to late January I had rested completely (roughly 3-4 weeks off) to avoid further damage. I came back recently and things seemed to go smoothly when doing drills but as soon as I went into the actual triple jump my shin started to hurt again, it seems to be quite a sharp pain. And also when I run my finger down my shin I feel a slight dip in the shin about half way down and when I press my finger down on this spot this is where all the sharp pain is coming from.
