Hello, The location and movement of pain give clues as to what is going on and often there is a (usually minor) underlying problem associated with pain.  Blood pressure that is not consistent and certainly when it is not done with a good 5 min of rest is NOT VALID for risk assessment.  The heart rate of 52 in someone who exercises a lot and has no cardiac problems nor symptoms strongly implies good cardiovascular shape. Localized, recurrent pain often means localized damage like (minor) arthritis. And simple x-rays often show it. MRIs would be a more sensitive indicator of problems. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
