I have been eating shrimp with shells to get glucosimine in my body because I don t like using pills or joint juice. I have been getting chest pains, stomach cramps, shoulder hurting, constipaton, and some times dizzy. But the pain in my meniscus and hip have greatly improved. But I don t think i can stand the side effects. I stopped eating the shrimp shells for over a week and the pain is just starting to go away. Is this normal?
