Four of my fingers are locking now from trigger finger and my hands are aching all the time. I have been taking 1 tbsp. of ACV in a glass of water 3-4 times a day, but no results so far. It was suggested that I soak my hands in ACV for 15 minutes a day using 1 part ACV and 3 of water. If this is an alternative, then for soaking can I use the regular grocery store brand as the organic is expensive for that purpose.
