['I hurt my elbow a little over a month ago, but I thought it was almost back to being 100% again.', "Glad to hear you're feeling better again.  How did you hurt it?", "Just exercising, but I tweaked it again last night and now it's hurting again."]
That sucks.  Maybe you need to be a bit more careful until its fully healed.
i hurt my elbow a month or so ago.  I thought it was on the way back to being better, but then yesterday I tweaked it again.
