In the end I lowered the weights for a while until the pain went down, then took it a bit easier when doing curls/tricep exercises (or anything that requires you to grip the bar hard) and it went away. Comes back occasionally and when it does I change to a different exercise and ice my arm as soon as I get home, seems to sort it out ok.
