Re: has anyone ever gotten forearm splints? (like shin splits but in your forearm)
I don't know much about that injury but it happens after tennis?
I don't know if you have but maybe try stretching it well before tennis and putting some kinesiology tape on it when you play. Could be just tight muscles.
Another wild guess could be old strings?
It is weird it's your non dominant arm.
