Thanks for the details. I would like to say that this seems to be most likely muscular pain which can give spasms. Anxiety & acid-reflux can also give such spasms. Acid-reflux can give inflammation of food pipe which can then give chest pain, burping and funny sensations in throat. I will suggest to see your physician for examination and some base line tests including serum electrolytes. In case of acid-reflex it is important to take antacids such as Syp. Gaviscon available OTC to start with and also important to avoid spicy or junk food, avoid alcohol. Also heart ECG to be on the safer side which is not likely.If you would like any additional information or have more questions please don't hesitate to ask!Please remember to only rate my answer when you are satisfied.
