so for the past 2 weeks i havent been feeling good. i had two incidents where i all of a sudden got major hot flashes, started sweating and then threw up (those two days were on a monday and a friday). i have also been experiencing: back pain, nausea, constant headaches, loss of appetite, cramping in my lower stomach, neck pain, heartburn, and frequent urination. i had my period as well but it was really light and only lasted about 3 days, which NEVER happens. i have taken two pregnancy tests both of which came back negative. i have been tested for diabetes and gonhorrea which also have been negative. Im not really sure who i should go and see doctor wise anymore. Any ideas?
