Question: I'm a 27 year old male. 7 days ago I was showering and not long before drank 3 tablespoons of salt in hot water (thought it was good for sore throats, later learned you're not supposed to drink it). During the shower my heart suddenly began beating hard and fast even though I was calm. After I felt really tired and sleepy and had a sort of squeezing feeling on the left side of my chest. The squeezing feeling continued, especially when I stand up from sitting quickly. I went to the E.R. the next day and they did an EKG and blood test and said it's not my heart. Since then I've been tired all the time and get lightheaded from any sexual activity. I went to a walk in clinic and they also just booked me for an EKG. I guess it wasn't a heart attack since the symptoms lasted so long, although I have heard of heart attack symptoms appearing weeks before an actual attack. Lately I've noticed some tingling and stinging pain in my left hand fingertips that comes and goes, also a few times noticed pressure in my neck and upper chest. My main concern is some clot or artery inflammation or heart related, should I be concerned about this and take some other measures or just let it be and hope it resolves on its own? I have a history of Viagra, cocaine and Steroids and my father needed a quadruple bypass in his early 50s. Although I haven't used any Viagra or Steroids for 2 years and haven't used cocaine for 6 years.
