General Unwell Feeling, Feel Hot & Sweaty But Have No

general unwell feeling, feel hot & sweaty but have no perspiration, then feel cold. Off & on day and night. Slightly shaky and anxious. Some other health issues (osteoporosis- 2 compression stress fractures- healing / in thoracic brace, bi-polar, chronic cough) but they are pretty much controlled. Sound like a mess but this is relatively new and kind of scary. ??
