I had a muscle pain in my back, my father in law gave me Naproxen. I only took one tablet but I am now experiencing stomach pain that comes over in waves (a bit like heartburn). How can I stop the pains, Ive not taken any more tablets, drink plenty of water and am doing moderate daily exercise.
Hi. First stop exercises as you have muscle pain in back. Naproxen is known to give this type of atypical pain in abdomen, do not take another dose (never in life in future). Take Sanitizing or a PPI, antacid gel 3 SF 3 hourly, Chilled water, light diet frequently. If this helps - no worry- if not you have to undergo an endoscopy
