I’ve been feeling numbness in my body and tight neck skin and also burning sensation
Been feeling dizzy every time I get up or walk also got really bad heartburn and the side of my stomach hurts feels like I have an air bubble there.
I can address the GI issues. Heartburn is usually easily controlled by taking Prilosec or Nexium which you can get over the counter. For the stomach pain, I cannot guess what that could be without more detail and an examination. It might be a problem of the ribcage or abdominal wall, not necessarily the stomach itself.
