osteoarthritis
"I have been taking Naproxen for 7 months 500mg and it is very effective but does have an impact on the stomach. I recently caught gastroenteritis and what normally lasts for 48 hours lasted 11 days, which may have been down to my weakened stomach lining. I was dehydrated and lost 1.5 stone. I am now going to try and manage the pain with ibuprofen and paracetamol."
