Suggest Remedy For Chronic Low Grade Fever And Low BP

I have had a low temperature for years, approx 35. I also have low blood pressure. I suffer from anxiety attacks, not a lot of sleep and a bad back with spasms. Recently I have had a bout of really bad stomach pains , low left side moving across my stomach, bent double with pain. First started about two years ago, couple of sessions after then twice in the past 4 weeks.
