After 8 months of daily elbow pain, an injection of ozone(!?) and seven weeks of physiotherapy I went to hospital again last week, courtesy of a "DL", a nurse friend of Jiajia's who arranged a "jump the queue and pay no money" visit to the top joint doctor there. He had a poke around and agreed it was "tennis elbow", but was concerned it had not improved over the months. He suggested the best way forward was a steroid injection to stop the pain, and a further 3 months of rest to solve the underlying injury. It's now a week later and the elbow pain has indeed gone. Quite a relief. Websites on the treatment suggest that such injections are only a temporary measure however, and I can expect the pain to reoccur in 4-6 weeks. Rest is the only long-term cure (barring an operation), so I need remember to take it easy for some time yet. It's certainly good to be pain-free at last, though.
