Undiagnosed Conditions

Hi,
Hoping someone can give me advise!
Lately i have been having problems off an on.Here are my symptoms.
Every now and then i will get really nauseas and just a real sick feeling.Seems to be more
stronger in the mornings.I went to the dr. and he did blood tests and that and they all came back pretty good.The only thing bad was my bad cholesterol was a little high he said at 150.And that i need to lose some weight which i am working on and allready new that.And that was it.No answer as to why i might get these feelings sometimes.Sometimes my blood pressure is borderline and sometimes my left ankle will swell when i've been at work all day.And sometimes i will have mild chest pain in my chest.My question is do you think i should maybe see a cardiologist to check for blockage maybe and maybe have a stress test done?I'm just not sure what to do.These nauseas symtoms i get no one seems to be able to help me.Both times they just took blood and that and said it was all normal.And the first time i had this checked out at the hospital they did an ekg and didn't find anything.So if anyone can give me advice what to do i would appreciate it.
Thanks
Mike
