Many patients have intractable hiccups during or after anti-tumor treatment. I have two prescriptions for you to try, which are clinically proven to be more effective: 1, oral heartburn (isosorbide mononitrate), while taking a piece of codeine phosphate orally; 2, acupuncture the foot San Li point. Foot San Li is an effective point of anti-aging, often massage the point, for anti-aging to prolong life.
