My father in law had a cerebral brain anurysm in December 2007. His expectation of living was 18 hrs. thank goodness he is still here. However he is again complaining of severe to moderate stomach pain again which happened prior to this CBA, although he never had it checked. Just today it got quite severe, should I be concerned that he may have a blood clot in his stomach and something is about to happen again. This has been going on for approx. 1 mth in the mornings but as soon as he eats it seems to disappear and has been moderate. It was not moderate this afternoon but after giving him stomach medication it went away. Again is there reason to be concerned and taking him into the hospital. Any response would be greatly appreciated.
