Ob-Gyn questions? Ask a gynecologist online.
How tall are you? How much do you weigh? Any weight change? Fast heat beats, diarrhea, high blood pressure? Does anything make them better or worse? When did they start? Are they consistent? Are they getting worse? Any other symptoms? Are you aware of anything which might have triggered them? Any medical problems? Any surgeries? Any other medications including over-the-counter pills and herbs? Any family medical history? Is your stress increased at home or work just before the symptoms started?
