Okay, it doesn’t sound like you have any real problems. You just did too high of a volume of high intensity work. Jumps will probably continue hurting for a while, but since you’re in season there’s no helping it. I’d just try to cut down on the jumping and plyo volume in your training and just jump at meets.
When you get the chance this summer, let your shins get some rest and when you’re fully healed you can start doing plyos again. But this time, add volume little by little to avoid this happening again. Like I said, you can also develop eccentric strength through heavy lifting and reactive lifting. Neither will mess with your shins.
