[|Human|] For the past two days I have been experiencing a fluttering/intense pulsing in my lower left back underneath my rib cage. Today I experienced two extremely intense shocks of pain in the exact same spot but they each only lasted for around 30 seconds. Any ideas?
[|AI|]  Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have fluttering pulses in back /rib cage. Well there can be many reasons for symptoms you mention in query like disc problem, muscle spasm, vitamin B 12 deficiencies, cardiac arrhythmia or angina. I would suggest you to consult cardiologist to rule out more serious condition. Doctor may order ECG, TMT, complete blood profile. Doctor may prescribe isosorbide nitrate, aspirin, beta blockers along with diuretics. Doctor may also refer you to orthopedic surgeon for disc or muscle problem. For now do not panic, take proper rest and apply warm compresses to back. Hope your concern has been resolved. Get Well Soon. Best Wishes,
