I had decades of it as a side-effect/result of acute RA. Primarily metatarsal. Regular contrast baths are very effective for joint inflammation. I’d sometimes dunk my feet in cold rivers and streams when biking. Just a few minutes makes all the difference.
At home aim to do one contrast bath in the morning and one in the evening. It’s easy for feet using two oval mop buckets! Put a bath towel on the carpet/floor with buckets on top.

Also cut alcohol for a while as can make inflammation worse (as can many foodstuffs, I went full ‘elimination’ diet to get remission)
Ginger and turmeric (in diet) helps too with inflammation. But the contrast baths effective and near instant. They can help break the cycle. Don’t skimp. This is not a cold plunge it’s contrast so you need hot and cold.
