Pain from 7 days. Already got 2 injection for pain (Tramadol) Report saying gallstone 21mm Surgeon gave some medicine including antibiotic and need to done some pre surgical report. Doctor told me surgery will be within 10-15 days till then take required medicine and take injection if needed. Today got Decolic injection along with rantac/pan40 injection(surgeon suggested). But pain not fully cured. Previously took Tramadol injection and pain was complete gone for 3 days(before we met surgeon) Every 3rd day pain appear. My question is - can we take Tramadol tomorrow if required as it was more effective?
