I had trigger finger for about a year, some days it worse than others. And then, it magically went away on its own. Then after a few days, it magically came back. Then it magically disappeared again!!
What did I do differently in the days when it went away? I simply stopped drinking keurig Coffee for about a week. I thought, maybe it's the BPA in the plastic, so using a french press, I made some coffee which came from a Keurig pod. Next morning the Trigger Finger was back. It's definitely the coffee!! Why, I don't know, but coffee has small traces of mold in it and I believe that's the cause.
