i am not sure what this is but it sounds serious. it appears that you have taken your son to the doctor already to get some answers and that they have ruled out several things. talk to your doctor again as you need to get to the bottom of his health problems. if you feel your doctor isn't taking this seriously you could try another one. ask for a recommendation from family and friends and make sure you have copies of his records and test results. trust your instincts. if you feel something is wrong then find someone who is willing to help.
