Hi Doctor
IM a 29yr old woman who recently started having heart palpitations that cause lightheadedness, blurry vision, anxiety, shortness of breath, sweaty palms. they can last to 30secs or intervals during my sleep. my blood pressure is normal, my sugar levels are also normal. they did a chest exray on me it came out fine. im now having vague pain in my left arm and left limb as well as involuntary spasms in my limbs. what could possibly be happening to me? i got beta blockers from my Doc but i dont see any change. My BMI is 28. Please assist, Thank you Doc.
