You need to see a doctor, those are serious symptoms.
I did and she told me to drink more water througout the day and I did that and it didn't help. This is why I am posting here....
I think you need a stress test.
Also she should check your sugar levels.
Good luck, I hope you get bettter.
DID YOU TRY LOOKING AT YOUR MEAL PLAN?IVE WENT THROUGH IT TOO A LITTLE.IVE FOUND THAT FOOD SOMETIMES,OR A CERTAIN FOOD CAUSES THIS.I LIFT WEIGHTS AND EATING IS A MAJOR FOCUS FOR LIFTING.JUST A SUGGESTION HERE BUT TRY ALMONDS OR GETTING ENOUGH ESSENTIAL FATTY ACIDS.HOPE YOU FIND OUT WHAT IT IS THAT IS WRONG.
Find a new doctor and get a second opinion.
If they give you the same answer get them to explain exactly how not enough water can cause your symptoms.
I am not aboslutely sure yet if this is the answer, but it sounds like exactly what I have...
