Chest Pain/Disconfort since May 2019

Hello everyone, Loudimus here but you can call me Lou.

So here's my story. In may I got a really sharp pain in my chest in the middle of the night. Went to ER, got a EKG and a CT scan. The doctor told me everything was fine, my heart was fine, and that the pain was most likely muscle related.

3 days later I got another sharp pain right below my left breast. I didn't feel dizzy, the pain was only in that area didn't radiate to shoulder, arm, neck, jaw, etc... I got up and walked for a bit and a few minutes later the pain was gone.

Since then I've been feeling discomfort in my chest but since may I was hit with a few illnesses. First it was a mild flu, lasted about a week, then I started to burp a lot and regurgitate stuff whenever I burped. I looked for symptoms and they matched with GERD.

Symptoms got way better around July. Every now and then I start to burp a lot and regurgitate stuff back up my throat but its very rare nowadays. But the thing that has me worried is that darn chest Pain/Discomfort.

The chest pain is always on the left side about 2cm up fromt he nipple and 4cm from the sternum. Sometimes it feels like pressure, other times like a getting stabbed, but the pain stays there. My arm feels fine, my shoulder is fine, no pain on my neck or jay. Sometimes I feel the pain at the back near the shoulder blade but it lasts for a few seconds or when I move it. Now, sometimes the pain is quite sharp and makes me flinch and this pain happens right next to the nipple on the left side of my chest. To me it feels like a heart attack, but I just feel fine overall, no nausea, no sweating, no dizziness, just the pain on the chest on the same spot every time. Also no shortness of breath. I can breathe just fine all the time, except for a few times which I'll go into detail shortly. The chest muscles on the left side also feel stiff, or tensed up. Whenever I get a pain of my muscles feel like that I check my blood pressure and it is usually 107/67.

Now here's another detail. I suffer from anxiety tho I have never had it checked. So whenever I get that chest Pain/Disconfort I get anxious, scared, and my heart rate goes up a little but never passes beyond 100 bpms it usually stays between 77-88 sometimes very rarely it goes up to 95. Also, when I sit down my chest gets tight but as soon as I get up or lay down it goes away. When I workout I feel normal too no issues at all.

So thats my little cherade, any help or counsel on what might be going on will be greatly appreciated!
