Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
The symptoms you describe might be caused by a virus you might be going through especially because they are happening for less than a week. A
viral gastroenteritis can cause
nausea, sweating, weakness and shakiness due to possible fever as well.
Make sure you rest, drink and eat well but in frequent small amounts (so you don't throw up).
BRAT diet (Banana, Rice, Apple and Toast) might be helpful. If you feel shaky and sweating please check your temperature and if axillary temperature is 38 or above you can take some
paracetamol or
ibuprofen (after food) to help with it.
If the symptoms last more than 3-4 more days or you are any worse you should see your doctor and have a thorough examination to determine the cause and properly treat it.
Hope I have answered your query.
Let me know if I can assist you further.
Kind regards,
Antoneta Zotaj, MD
