I went to the ER weeks ago and for a CT scan on my chest and bloodtest &amp; a physical and everything looks fine but for the last 3-4 I’ve felt so dizzy &amp; sleepy with bad headache, lightheaded feeling like about to pass out and my chest very tight and i’ve felt sharp pain on my chest for years and everything was good even got checked like 2 years ago and like I said another CT scan recently but since yesterday I’ve been getting sharp pain on my chest on the heart area every few minutes or every hour or so and today it’s same thing right now my head feels lightheaded,dizzy im extremely tired and I went to the ER today and got checked with EKG and everything was fine and they told me to get ibuprofen but the tight neck the head fog,dizziness, headache and chest is both horrible and scary… I can’t even function right I went to work like everyday feeling like this… (I also got a CT scan on my head back in 2019 because I was getting sharp headaches and everything was fine but I’ve felt sick and miserable for the last 3-4 weeks) I’m 26 yrs old and I’m on the weight that I suppose to be and my family doesn’t have a history of heart attacks and I don’t smoke or drink. Most of the times I have fatigue and my head feels hot and can’t sleep right quick also my vitamin D is 20 which is low
