Best wishes to you and your Dad, as Jaysit said, they caught it early and that's a huge positive.
Antibiotics are in a way victims of their own success over the previous decades, but they'll get to one(s) that do the trick in time, it's a cliche I know, when people say 'don't worry, they can perform miracles these days', but there is much that is true in that statement.
And as has been said too, he IS
in the best place, that he's missing home even now, and all the routines of everyday life, is also such a good sign, the right frame of mind to be sure.
My own Father died in 1997, aged 64.
In 1980 he contracted Multiple Secrosis, typically for him, he was determined to keep on working, keep on driving, he would not have been able to do his job as an engineer, but his factory soon closed (Hoover in West London), so he threw himself into a clerical job with the Civil Service, which he was able to do until 1988.
At this point he could no longer drive, but he joined a local support group which provided advice, social evenings and holidays.
And many real friendships.
However, this illness is relentless, and he became very ill in 1997, it was a very aggressive stomach cancer, and he was of course now much weakened by the MS
But the hospital made him as comfortable as they could, though weak and heavily medicated, he could still make a witty remark or two.
Inevitably he passed away, peacefully, in the early hours of the 9th September.
A tough time of course, but amongst all the sympathy cards were some from those who had only known him briefly at the civil service 10 or 15 years before, saying what a great guy and an inspiration he was to them.
As for my Mother, she still keeps in touch with the MS
support group, socially and in fund raising.
But I'm sure your father will recover, and when he does, he'll take something positive from all this.
I found this myself, in late 1999 I started getting pain, sometimes in my legs, sometimes my arms.
By Christmas it was getting frequent, and worse, I now had to tell my family, who of course told me to get to the doctor.
After a battery of tests, all OK
, normal even. I was told to rest as I may have a virus.
But the early months of 2000 found me getting worse, then some swelling in my fingers and knees, now they had something to go on.
A spell in hospital confirmed what was suspected, Rheumatoid Arthritis.
So a host of medication, advice, exercises, hydro-treatment
But luckily for me, they had caught it early.
Any self pity I may have had soon went when I saw less lucky sufferers, those who got it very young, or more aggressively, or who had problems with medication, or who got it years ago when medication was much less effective than now, so had suffered permanent damage.
The drugs and other treatments started to work, by March, just before hospital, I could barely walk, by April I was back at work on reduced hours, I had kept working, on reduced hours and light duties up until late Febuary, but it was tough and my workmates were clearly concerned as I got worse in my movements.
By May I was walking pretty normally, one day I was feeling particularly confident, I walked in the hangar and some workmates commented how I was walking so much better now, so I said "watch this"
Our crew room and control centre was up two flights of stairs, I had always run up them before getting sick, and today I did so again, easily.
My colleagues cheered, I was so happy, so relieved, so thankful for all the support, I went to the (thankfully) empty crewroom and wept.
That's what I mean by taking something positive from this sort of experience.
Today, I'm fine nearly all of the time, do what pretty much what I used to before, flare ups are getting more rare (many months apart), and of far less effect than in the past.
Only change is really having to be teetotal, alcohol does not mix with the medication I'm using, a small price to pay.
I had learned that I had more determination than I would have thought before.
It will be the same for your father when he is fit and well again, he will bounce back, and your support (which you are certainly giving him) will be a big part of it.
Easy to type on a keyboard to 'be strong', but it's true.
Keep us posted, and again, the very best wishes to your dad for a full recovery.
Hang in there for him.
