Hello, I Have Been Feeling Sick For Over A Month

Hello, I have been feeling sick for over a month now. My BP has been high (for me) and my doctor doubled my BP meds, but it still seems high and goes up and down. I have been having hot flash like symptoms but I feel sick when it happens and my heart beats faster. It's not like a normal hot flash. I've had similar feeling before, and ended up on antibiotics which cured all symptoms. However, the high BP is new. I see my doctor tomorrow, but she just thinks I'm going through normal menopause - but this is different. I've also had a yeast infection and rash that doesn't seem to want to go away. Could that be related?
