I took my pulse it is 48 with oxygination of 94. I also some have some chest discomfort, should i be alarmed?  <response>: Hello, Would explain that this heart rate and blood oxygenation or quite normal. Coming to this point, I would recommend taking Tylenol or ibuprofen and an antacid. A viral infection may mimic this clinical situation. If this situation persists, I would recommend consulting with your GP for a physical exam and some tests: a resting ECG, complete blood count, PCR, ESR. Hope I have answered your query. Let me know if I can assist you further.
