my husband has severe heartburn most frequently at night ...trouble sleeping through the night, recently his blood pressure was 230 over 180....he has periodic blurred vision, more so in the left eye, a gurgling in the heart sometimes...when that happens he has pain for about 10-15 seconds then it passes...he is extremely fatigued, has abdominal pains on the left side, and has episodes when driving where he feels as if he is going to pass out and by the time he gets home he is pale and clamy and lathargic followed by 2-3 days of extreme sleep, unbalanced walk minimal appetite. We have been to the doctor and no one seems to have a clue or a diagnosis??? Please advise.
