Joyce, regarding your shoulder issue, both my husband and myself have rotator cuff issues. We have had very good results with turmeric powder. We take 1 teaspoon 2 or 3 times a day. We either mix it with a glass of milk or scramble it into our eggs. Add a dash of black pepper and some fat (we use coconut oil or butter) for better absorption.
We both noticed improvement starting on the 3rd day or so. It's marvelous!
