God Bless your neighbors & friends.
We are richly Blessed that you are still with us Frank, I will be saying many prayers for your quick, full recovery.
I don't know if you are a dog man Frank, if not, go with the cats.
There is much study on dogs today that can alert their owner to a seizure, low blood sager, epileptic problems and much more.
I believe they go by smell, when our body's produce something that changes our smell dogs and cats can be trained to pick it up.
I myself had a very odd experience with my Rottie. For a couple of weeks he kept licking my shin, one day the just head butted me so hard I thought he had broken the bone.
X-rays showed a huge tumor that was eating away at my leg and darn that started the nightmare.
MRI sent me to a cancer doctor in Boston who was ready to amputate the limb. All came out well, biopsy's showed the tumor was benign but I needed a human bone implanted into my leg. Gross.
The dog had saved my life, just a pet that smelled something wrong.
In the works one may find a dog that can tell when blood pressure rises too high, when a stroke is on the way.
My neighbor was awakened by his cat one night, he in his min-fiftys got up to see what was bothering the cat and found the bed sheets bloody.
A vain in his his leg had broken big time, He would have bleed to death in his sleep had the cat not bothered him.
Then there was my daughter 10 years ago that had Hep C and the veins in her throat and stomach exploded. We put on the flashers in the car, could not wait for an ambulance to get her and drove 90 mph to the hospital. The car looked looked like a carnal house, blood dripping from the ceiling.
With drugs, blood infusions and banding the ruptured veins, she is still alive--even the doctors don't know why.
She was told to stop smoking, drinking and follow some healthy plan. She did neither, still smokes, drinks and takes her medication every day.---and is still alive and functioning.
Every one of us is an individual, no Doctor can use the same treatment on everyone.
You have had a very big wake up call Frank, if diet and exercise does not help, remember a spoon full of sugar makes the medicine go down. Take your pills, the way you are told to, don't skip a dose and never stop taking them until the Doctor says you can.
Carry your bottle of Nitro in your pocket at all times, first one don't work take a second, if that don't work call an ambulance.
Whatever you have to do, do it, God for some odd reason gave us guardians in the animal world, pay attention to your cats and if along the way you can find a small dog that will alert you to a coming problem, thank God for sending them to you.
