Dear Sir/Madam I have gone through your query and read your symptoms. In my opinion, looking at your age taking too much of ibuprofen is not good for stomach and overall health. I would like you to see your doctor and get examined, because without seeing you its difficult to find the cause of your pain. once we are able to manage the cause, your requirement of the analgesics is going to reduce, moreover you can take more safer durgs, like etoricoxib. I hope that answers your query. If you want any more clarification, contact me back.
