In reply to MDS87:
"... I know there's a lot of info on climbers elbow out there but that seems to be a longer lasting pain than what I'm finding, is this just case of not warming up enough/bad technique/weak tendons that need strengthening? Or should I leave it a while before going back (hopefully not the case!!)"
Probably all of the above, just ease right off for a bit and do loads of really easy stuff, even those of us who have been doing it for ages have problems if we suddenly increase climbing intensity and frequency. I'm currently trying to shake off climbers elbow but have been struggling to stay away because you need to take advantage of the good climbing weather in the UK. Fortunately/unfortunately I've another injury that I can't climb at all with so the elbow will get some time to heal.
