Hi! I turned vegetarian over a year and a half. At the beginning I was perfect, but now after every time I go hiking, my joints hurt. For instance, yesterday I returned from my weekend hike and at the end, my ankle began hurting and it isn't going away. I am scared it'll happen the same as the last time. My waist acked for nearly 4 months!! What can I do? Could this be cause I am not eating enough of something?
