A little success with grounding
I am aware this takes me into slightly controversial territory. I tried grounding first a number of years ago to help with general inflammation related to chronic conditions and the results were very apparent. I tried it again a couple of weeks ago and realised how much better and lighter my legs felt. I live in an apartment so I can only do this occasionally. The best my legs have felt for years was after 2 hours laying on the sand at the beach followed by an hour long swim in the sea. I am a novice at all this and have only tried Pilates,Yoga and Swimming so far, so not an expert on methodologies. My skin on my legs even feels smoother. It is viewed as pseudoscience by many and but equally alot positive anecdotes for dealing with inflammation, including mine.
It's free if you have access to a patch of grass,soil or sand, low effort/energy required and unlikely to worsen the condition unlike more aggressive options such as the vibration plate for example.
