I had this sudden pain on the left side of my chest last night, and it kind of felt like there was pressure in my throat too. It went away after about 15-30 minutes, but theres still a bit of chest pain lingering. Any idea what might be going on? Im really worried.

Based on your description, it is possible that you may have experienced a muscle strain or inflammation in your chest wall, known as costochondritis. This condition can cause sharp, stabbing pain in the chest that may worsen with movement or deep breathing. It is usually not serious and can be managed with over-the-counter pain relievers such as ibuprofen (e.g. Advil) taken at a dose of 400mg every 4-6 hours as needed for pain. However, if the pain persists or worsens, it is important to seek medical attention to rule out more serious conditions such as a heart problem.
