I am a 50 year old woman. My left leg hurts from the hip down. I am in another country and the water contains salt, so I dont consume as much as I usually do back home. Recently, 3 days ago I ate at a local restaurant and awake that night with diarrhea . I have had it every since. I thought it was getting better after breakfast today, because it was softening, but tonight after dinner, it is back. I was wondering if I could be dehydrated and that is why my leg and lower back hurt. Can you give me some advice.
