I feel like my throat has been tight as if I had taken a pill (which I have not) for the past 2-3 days, should I consult a doctor?

Based on the symptoms described, it sounds like you may be experiencing acid reflux. This can cause a sensation of a knot or pressure in the throat, especially after meals and when sitting down. Before seeing a doctor, you could try using over-the-counter medication like Zantac to see if it helps alleviate the symptoms. If the issue persists or worsens, it would be best to consult a healthcare professional for further evaluation and treatment.
