Well let's see here...
Grandson's skateboard accident was a bad one, open and bleeding cuts and wounds for both of the boys;
I'm sorry that happened, but I don't believe a single incident of blood mingling confirmed only visually (nobody can tell if the other boys blood penetrated your grandson's skin) proves that is how he received the HIV virus.
When I was a teenager of skateboarding age, kids my age were doing those recreational drugs that can cause the AIDS signature diseases. I had a girlfriend who died of AIDS; she was a recreational drug user, not a homosexual. Same for another girl I knew, the girlfriend of a friend of mine.
When I was a teenager of skateboarding age, kids my age were having sexual intercourse and exchanging sexual diseases within and outside of their social groups.
I'm not suggesting that your grandson did any of those things, Psalmist. I am simply making the point that there could be many causes for why your grandson has the HIV virus that would be consistent with scientific evidence; but the freak skateboard accident doesn't seem the likely cause of his infection, in my opinion.
And I'm not saying any of this to offend you, but to suggest that you may be able to help your grandson by finding the true cause of his disease, by ruling out first the false cause of his disease.
... he was notified within a few weeks to come to the clinic for an evaluation; he is on daily HIV meds,
Before I would take a medication with harmful side-effects to attack a virus, I would first need to see scientific evidence that conclusively proves the virus is the cause of the disease. That would be the starting point for informed consent if I was offered the treatment. Since that evidence doesn't exist, obviously I would never take those drugs. I would also see that the efficacy and safety of the drugs is questionable.
he has to be careful not get cut, and avoid the best he can getting a cold or the flu since his immune system is weak;
His immune system could be weak for number of reasons, but primarily because he is in "protection mode" most of the time, falsely believing he has a terminal disease that could take him at any moment. The extreme of belief effecting health can been seen in phenomenon like
voodoo death. That perception controls biology is just being understood from research in the last decade or so. I believe your grandson's problem is more his perception than a virus that hasn't been scientifically proven to cause the disease(s) he is receiving harmful drugs to treat.
...when they moved from Denver to northern Indiana, he couldn't travel unless he all the meds he need for the trip and the move. Grandson manages holds a job to support his wife and daughter.
That is admirable, but sad because his situation was/is preventable, in my opinion.
As for a Dr's speculation and scientific evidence, if he wasn't in this condition he wouldn't be taking the meds and and having to do blood tests every two weeks, and knows what bad days are, he has had a few.
I believe that is a non sequitur, brother. If you read back through all my posts in this thread (not too many), then you will likely understand why I can factually claim there is no evidence to prove the doctor's wild speculation and, in my opinion, medically negligent treatment protocol.
