UPDATE!

Can you believe we have more good news?  WE DO!  We met with the doctor and he gave us a very encouraging report.  They are 90% sure it is Valley Fever which he caught in Tempe, Arizona.  It is a mold that is air born and not very many people catch it but due to his low immunities and heart issues he was more prone to catch it.
Anyways a few hours ago I went in to see Dad and was talking to him a little bit and HE OPENED HIS EYES!  I couldn't believe it!  I screamed!!:)  He has been sedated for a few days now and he hasn't responded to us much at all but this time he did AND he even nodded when I asked him if he knew it was me!  I was thrilled...thank you Lord for this moment!!
We are all very encouraged but we do know he is not out of the woods yet.  It can be a very long recovery time and he is still in the ICU and will be on the ventilator for the next week for sure.
They sat him up for a few hours today and he seemed to like that.
It is nice to have some good news and be closer to a diagnosis!!
BTW there is a treatment for Valley Fever but it can be a very long recovery time.  If you happen to Google it don't believe everything you read,  that's the worst case scenario most likely.  My Dad is strong AND he has the Lord on his side...we're gonna bet this!!!  Please continue to pray we are feeling the prayers!!  Keep them coming!
