Several possibles: What you describe is suggestive of a overactive thyroid, diabetes mellitus, an autoimmune process like Lupus, Multiple Sclerosis and severe anxiety on its own or in combination with a disorder like or similar to the disorders listed in this note. You need to see a doctor as soon as possible for blood tests, a through physical examination and other testing deemed necessary to reach a diagnosis.

Need to see doc: Are you under stress? Some of your symptoms sound to be related possibly to non physical conditions. Suggest see an internal medicine physician for a physical and review of medical history and exam.

Time to see the doc.: You may have a UTI Need to go for check up and urine test and if not had full check up go for a complete physical and labs

Bizarre symptoms: These symptoms could present from a lot of different causes.
