All NSAIDs have cardiovascular and stroke warnings.
I've taken Aleeve, OTC strength was useless. Prescription strength Naproxen helped some, but I had to quit taking it due to it being too tough on my stomach. It is listed as one of the NSAIDs that are tougher on GI, along with aspirin.
Ibuprofen stopped working years ago, both OTC and prescription are useless to me.
I currently take Nabumetone, a prescription only NSAID. It's about as tough on the stomach as ibuprofen, only needs two doses a day, and seems to actually help inflammation.
In any case, if an OTC doesn't seem to be helping then don't take it. Get a doctor's opinion and see if there is a med appropriate that will help your inflammation. Don't take extra doses to try to help pain, NSAIDs are not painkillers - once the damage is done to an area you'll still feel pain from it till your body heals (if it can). There's lots of NSAIDs of varying strengths, and if inflammation is bad enough your doctor may have to prescribe something else entirely.
Also, don't take an NSAID on an empty stomach, ever.
