My non-verbal 33yr old son for the past 8 mos. has had severe pain in either the throat area, or chest, abdominal area, or stomach. It can happen either when trying to eat/drink or just sitting/laying around. He has gotten to the point of not eating/drinking because of the severity of the pain. Have had lots of test, have found tumor on liver, several heart problems, but nothing that would be causing this type of pain. I don't know what to do next, because of his rare syndrome LGS he cannot be put to sleep for some test. His seizure's are going even more crazier than normal. Could you point me in a direction of what else it may be? Thank you and God Bless
