I know this is cheesy, but OMG I have found my people. I love this thread so much, and it's making me want to weep with joy. 
Mainly because I don't feel so alone now. SO many men are the bloody same!!! My DH (aged 54,) displays ALL of the above mentioned, and sometimes I want to cry with frustration, and actually seriously wonder how much longer I can tolerate it. I swear he never used to be like this. (We have been together 30 years, and he has been like this for maybe 6 years or so...)
I mean when he was younger, he would moan about stuff like bad drivers, youths, people at work annoying him, etc etc..... but not his health. He never even went to the doctors for 20-25 years. But he started going about 6 years ago, (when he had an actual genuine 'small' ailment,) and I haven't been able to keep him away since.
I swear he has had about 15 different ailments in the last 5 or 6 years... heart beating funny, constant headaches, dizziness, bad kidneys, brain throbbing, bad shoulder, something wrong with his eyes, a painful hip, a painful knee, and numerous other ailments .. some that have been mentioned by other posters.
Then it's the 'dressing gown of doom' and the 'slipper shuffle of suffering' (LOL at these!) He ALSO huffs and puffs and groans and grunts, and sits in his chair holding his head in his hands, rocking back and forth, whilst massaging his temples.
He also blathers shit like 'will I ever feel well again?' and 'You best learn stuff like changing a plug and changing the tyre on the car, because I'm not long for this world, and you'll need to do it yourself soon.'
And he regularly says 'I'll be dead before I'm 60 I will..... YOU will live a long time, probably to 90, but I'll not live that much longer...' 
For the last 5 or 6 years, he has not been ailment-free for a single moment. He has had around 15 ailments in that time, and only 2 have been genuine (and they were trivial, and were remedied and cured fairly quickly.)
Last time he went to the doctors, I went in with him, (as he asked me to,) and I could see the doctor was somewhat irritated by him. Especially as he has had test after test, and scans and ECGs and X-rays and blood tests galore, and nothing serious has ever come up. He must be costing the NHS a FORTUNE. 
Why are men like this WHYYYYYY???? Women have SO much more issues and health problems than men. Yet we rarely complain.
Another thing is, whenever I say I have anything wrong with me, and I complain (which is rare!) he ALWAYS ALWAYS ALWAYS has to 'top-trump' me with something much worse. I get so sick of his issues always being sooooo much worse than mine. 
I said to him once (about 2 years ago,) that I didn't understand how and why he is ALWAYS 'ill' and why he always has something wrong with him. I did suggest he had health anxiety. He absolutely hit the roof, and was fuming that I was accusing him of LYING, and sulked for 2 days.
I said 'I am not saying you are LYING, or making anything up, I am just saying that could be imagining some of the ailments, because despite multiple tests and scans over the last 3-4 years, they have found NOTHING. (Which they hadn't at that point.)
About a week later, the entire conversation was forgotten, and once again he started the carping and moaning, and started shuffling about in his dressing gown, coughing weakly, and lying back and closing his eyes, or leaning forward, rocking back and forth.
I think I may murder him one day... soon. (So he will be right about ONE thing... dying before the age of 60!!!) 😈
