I am looking for some answers as well. My baby brother Mike has had Hep B for about 15 years, the result of unprotected sex with a know needle user. I am truely over her, but now I have to deal with another loss. My older brother died of AIDS 10 years ago. Mike has these attacks too. he has lots of pain and is currently in the hosp. the doctors won't tell us much, but gotta love those nurses. they told me his blood ammonia was up to 45, should be 29-32. go online and reveiw these symptoms.mike has so much pain at times he cannot stand up. we think his hep B is progressing based on his exposure to industrial chemicals or mold spores. he builds roof trusses and when the wood gets moldy his company just washes them with industrial bleach. he breathes that crap in and he also handles the wet wood bare handed. i am looking for some answers--i will keep you posted if you keep me posted--se a specialist--if your HMO or isn co needs a referal and your dr won't give you one, the next time you have an attack go to the ER, give them your family history and make sure you tell tham how long the pain has been going on. Keep God foremost in yor mind and ask for his help. Reward may not be on your time schedule but He will help.
