Intense kidney pain and stabbing pain in left chest btw ribs, armpit, and left thigh near groin. Ekg fine, said endometriosis could be cause?

Diagnosis needed. Pain is the main symptom in endometriosis. A cyclic pattern related to the menstrual cycle is common. The diagnosis is not made by blood tests or ultrasound. Instead, a diagnostic laparoscopy is needed and biopsy or removal of suspicious lesions.
