A friend's been using email oil for years to reduce leg pain and swelling. The company he used to order from closed when the owner retired but she referred him to Clearly Emu as they had her strict standards for emus fed organic diet and producing cold-pressed oil food-grade oil. I have no affiliation with them and there might be other quality-assured sellers, especially in Australia and New Zealand but the Clearly Emu's Triple-Refined and AEA Certified has a website. If I can help with more info, please message me and I'd be happy to try. I will add that a Chinese physician we know now uses the oil too, after seeing good results in 'moving chi' in patients. I've seen it do some pretty amazing stuff but that's just anecdotal. It's not risky or expensive to try at least.
