COVID restrictions then shin splints which hurt like the dickens and take what seems like forever to go away. Tess is a shooter and it is not surprising that an injury like this could affect her shooting eye. Not worried about her at all. She will be fine when all this stuff is in the rear view mirror.
I posted this before but the phrase shin splints really understates how problematic this injury is. The more accurate med term is medial tibial stress syndrome. Essentially, an athlete is having a stress reaction in the bone which with continued irritation can result in multiple stress fractures.
The big complication is that there really is no mild case - once it kicks in, you have to rest and rehab to get the condition under control.
When my daughter was diagnosed, the sport med doc said there is not point in doing an MRI to see how advanced her injury was because you treat it the same, whether it is just pain or an actual stress fracture. 6 weeks of rest and then 6 weeks of rehab with a gradual return to play.
So, Tess likely has been away from conditioning for a while.
