I don't think you are being unreasonable, but knowing what to do about this is more difficult.
Are the colds bad enough to attract your attention, or is he just saying he has a cold?
Colds and sore throats can be caused by allergies, although this is the least common reason for them. Is there anything in your house your husband could be allergic to?
It is usually difficult to get a man to consult his doctor, but suggesting that he has an allergy might do the trick.
Sore feet is so vague - are they worst at any particular time of day+
I suggest you leave the health issues aside for a while, and start by making a written household budget of all your expenses and detailing whether they are covered by your or his earnings.
Sit him down and tell him that you are seriously concerned about how you will be able to pay the bills/ maintain your present standard of living when you retire.
Show him the budget and remind him gently that he only earns on the days he works, so his ailments worry you., both because he never seems really well and because of the financial implications.
See what he says.
You could also ask him whether he is worried about his work or tired of it and is taking days off because he cannot face his job.
It sounds to me as if his days off are affecting your financial situation. If this is so, it won't get better, unless he is either able to work more, or to charge more for the work he does.
Do you want to continue working? If not, you need a frank discussion of the financial outlook for the next years until your husband can retire as well.
Changing his job at his late stage will be well-nigh impossible, so either you have to make changes that enable you to live on your pension alone, or he needs to work more, or qualify for an invalidity pension.
Please do try to discuss it with him now, both the financial aspect, his poor health, which to start with you should treat seriously, even if he is merely putting it on, plus discuss how you visualize retirement and the years to come after you have retired and he cannot.
