I'm dealing with this chest pain for the last couple of months, and I've already checked in with a gastric specialist and taken some gas meds. Even had an ECG done and that seemed fine. But I'm still feeling this pain when I move around or lift stuff. Could this be a muscle issue in my chest? Should I be worried, and is there something specific I should be taking to help with it?

Based on your description, it is possible that your chest pain is indeed related to chest muscle pain. To help relieve the pain, you can try taking over-the-counter pain relievers such as acetaminophen or ibuprofen. Additionally, you can use a muscle relaxant such as methocarbamol to help relax the chest muscles and alleviate the pain. It is also important to rest the affected area and avoid activities that worsen the pain. If the pain persists or worsens, it is advisable to follow up with your healthcare provider for further evaluation and management.
