Hi, i am female in early 20s and over the last 2 weeks I have had increasing bouts of the following: dizziness and feeling faint nausea lack of appetite dull headache weak and tired/fatigued hot sweats occasional pins & needles in left hand I couldnt get to see my own GP so went into a walk in centre who wasnt too sure of my conditions but gave me some tablets which were related to vertigo (5mg to be taken 3 times a day only). I have not had nausea since but i still have the other symptoms even after having taking the tablets and these probably occur around 5/6times a day. I make sure i am well hydrated throughout the day by drinking lots of water although recently i suffered a heavy period so not sure if this could have had an affect?
