I have been having body cramps, aches, fatigue , headache, dizziness and I feel weak and I can't seem to study or concentrate on anything . It's hot here the place I'm staying and I think it's fever I'm having and I took some medicines my family doctor told me but when I go to my university's hospital they say I'm fine cause my body temperature is normal . I've always had fevers with not much body heat from when I was young . I don't know what to do I feel nauseous and I can't concentrate . I got loose motions with blood too a while ago 

please help me I have exams and I can't do this anymore it's been a month I've been feeling this sick
