Hello, As you mentioned about the pain location in the history I think you should get cleared of your doubts. Get and abdominal scan done so we can figure if any organ is involved. Along with this do routine blood and urine tests so we correlate and provide some inputs. In case the above ones turn out to be normal than we may need an MRI scan of the lumbar spine to rule out any pathology of the spinal nerve roots. as sometimes there is the possibility of nerve getting entrapped and less to symptoms. Even if this turns out normal then it can be the wrong way of doing exercises leading to such pains. It is always advised to take calls step by step so a good diagnosis is made and treated accordingly. Hope I have answered your query. Let me know if I can assist you further.
