I've been experiencing these sharp, needle-like pains in my chest that come and go within a few seconds. At first, they were on the right side, but now they're also happening on the left and sometimes even under my left arm. This all started after I began having that burping, indigestion feeling last week. I've noticed that physical exercise gives me a bit of relief, but it still feels like maybe there's a burp stuck in my chest or something. Should I be concerned about this?

Based on your symptoms, it sounds like you may be experiencing symptoms of acid reflux or gastroesophageal reflux disease (GERD). To help relieve your symptoms, you can try taking over-the-counter antacids such as Tums or Maalox. Additionally, you can also try medications like Omeprazole (Prilosec) or Ranitidine (Zantac) to reduce stomach acid production. It is important to avoid trigger foods such as spicy or fatty foods, caffeine, and alcohol. If your symptoms persist or worsen, it is advisable to consult with a healthcare professional for further evaluation and management.
