Ever since i was a kid during physical activity i would have horrible pain that felt just like my severe abdominal cramps that i have during my menstrual cycle. it doesnt matter what time of day/weather/or if im hydrated or not it still happens.

Your body is talking to you. Listen and take good notes and then share with your Dr and you all will figure it out, Drs can hear your body talking, Only you can tell them.

An assessment of your metabolic laboratory tests when this occurs may be helpful. Drinking a sports electrolyte solution is often effective in reducing cramping. Stay well hydrated and avoid heat stroke. Exercise in temperate and shaded environment.
