Hi, I've hit a ball lightly once in the last 6 weeks, that's it. It led to mild discomfort in my elbow, which I'd strained 6 weeks ago. It's not tennis elbow. When extending or bending it fully (to the max levels of the other arm), it feels sore, and this was exacerbated by the light hit, though not by much. Is a little bit of discomfort when starting again usual, and therefore something to be managed carefully while building up your hours on court, OR is it something that tells you to give the injury a little more rest before hitting the courts again?
