* A BIT OF A LONG POST SO BARE WITH ME PLS* 

23 f. Ended up in A&amp;E (emergency room) about 5 days ago because of chest pains that I have been having for so long but they just got worse and more frequent (sharp, stabbing, can be burning) so basically I got to the hospital and from walking up to the reception which was like 2 mins I’d say I had only walked my heart was beating so fast and I got this weird feeling in my chest as if it was burning, you know when you have like ran really hard doing exercise and it goes into your throat that feeling ? I told them how I was feeling and they brought me straight in after my heart rate went to 170bpm. My heart rate started to go down after about a minute or 2 and went down to I’d say about 100bpm maybe and as it was slowing down it started skipping beats. Long story short I had 2 ECGS, a chest X-ray, bloods, oxygen levels and blood pressure were perfect. A doctor said to me it’s still odd how your heart rate is still a little high (104bpm) and I was just sitting down. I told her I suffer massively with anxiety and panic attacks but the last few months the symptoms have gotten worse and more frequent and we both concluded I could have POTS as my heart rate goes back down to normal when I lie down. Said I need to go about get a holter monitor done. My own doctor (PCP) noticed my heart rate was a bit high when he took my blood pressure when standing a couple of months ago and said oh that could be just anxiety. I have daily symptoms everyday:

• Vertigo/dizziness - suspected inner ear problem from my doctors as I have minor hearing loss in my right ear. 
• Ringing in ears.
• Visual snow - my vision looks static and is worse at night. That is 24/7. Throughout the day I will see black dots that flash for like 1 or 2 seconds, they can be colourful aswell. Also see floaters. 
• Palpitations - flutters mainly after eating, races when I move around and walk. Also sometimes skip when my heart goes very fast and I crouch down or something. Sometimes burping relives palps.
• Chest pains - can be sharp that last for 2 seconds where my heart is on the left side, right side, sternum, etc. 
• GERD/acid reflux symptoms. 
• Headaches. When changing position or moving head it pounds. 
• Pains in arms, legs, back, neck, jaw. 

What is scaring me the most is that my heart rate goes so fast when I walk for like a minute or two outside like when it did when I went up to the hospital that has happened numerous of occasions the last few months and it scares me thinking I have a heart problem. I’m completely bedridden with all of these symptoms the dizziness and the palpitations are the worst and most people and doctors keep telling me it’s purely anxiety but it feels so much more than that. 

Can someone give me any advice or can anyone relate to this?
