my friend has had over the past two years periodic episodes of trembling, nausea, vomiting and fatigue that last several hours and are gone. these spells are seemingly random. lately he has developed a metallic body odor.
Trembling, nausea, vomiting and fatigue... panic attack? among other possible causes.
As to the metallic odor, it could result from aldehydes and ketones (when you touch metal objects, your skin lipids emit these substances so people tend to call it metallic odor). It could be because of COPD, fungal infections, metabolic problems.
