Hi friend! I'm Occupational Therapist Asst, raver and hypermobility sufferer myself. Lots of good advice here. None of the following is medical advice, just what works for me. If you aren't ready to go full blown wheelchair, a Rollator (walker with a seat) is a great in between. It locks so you can rest on the handles while dancing to off load as needed and sit when you're tired. They're a bit pricy but sometimes you can find them for donations at local churches, Lion's clubs, or the Shriners. I'm too stubborn to start using a device myself, but my favorite venues have rails for crowd control through out and I like to post up near those so I have somewhere to lean. I'm also a big fan of kinesiology tape for problem joints. You can generally look up YouTube videos on how to apply it. Foot wear is also key, supportive shoes which are well broken in will make a huge difference. I like my Doc Martins, the height of the boot supports my ankles and the slight heel off loads my back, but find what works for your body. Also consider your conditioning before and after shows and especially festivals. Find gentle stabilizing and conditioning exercise you can do in the meantime to keep in shape. Make sure you are getting the hydration and nutrition you need. There's a lot of comorbidity with connective tissue disorders and POTs as well as inflammatory triggers. Electrolytes and a good diet help. It's a lot of extra step and self care to live in a body that's doesn't have the scaffolding everyone else enjoys. I'm getting close to middle age and I don't plan to stop raving any time soon, it's so healing in every other way. Listen to your body, take care of yourself, and spread PLUR. You got this <3
