My Dad constantly complains about his health, yet does not do what the doc tells him in terms of getting enough sleep, drinking lots of fluids, etc. I am really starting to wonder if this is just attention seeking behavior. Dad is 80. I ask him if he needs help, he says no, then he says I dont help him enough, or he waits till the last minute to ask, I tell him I will try to get to whatever it is, then he says never mind, he will do it, then a few days later says I "refused" to help him, and that I should "Lend a hand" more. He will go on and on about himself for hours if I don't politely excuse myself, and he rarely asks how I am doing- I have back issues from an accident, and possible Sjogren's Symdrome. I havent mentioned the possible Sjogren's to him because I am not sure and he he often brushes off any health concern I have, and I am quite concerned about the Sjogren's, and if I mention it and he brushes it off/minimizes it, I lose I will totally lose my temper with him. He has been like this his whole life, my Mom had eczema, and he often mocked and ridiculed her. Every thing is about him, him, him, and he really contributes to his own health problems. Strangely, he can be very generous with money with me but sometimes a little too generous with people outside the family.
Ours takes 25mgs of Sertraline, it is a small dose of antidepressant but takes the edge off, off label use is that it is to connect the neurons and receptors.
The other question will be, is it dementia?
When he complains to you about a certain symptom, ask "have you talked to the doctor's office about that?" If he has, follow up with what they said and whether he is follow that advice. If he hasn't, suggest that they'd know better than you do how to deal with this. If his insurance provides a nurse help line (and many do, for free) suggest he call that number to discuss his symptoms. I don't mean that you should be unsympathetic or never listen to health complaints, but you might want to set a limit on how much you listen to. And if you are concerned that maybe something should be seen by a doctor, you can use that help line, too. Have your father's insurance ID available for this.
It sounds like you really do know how not to get suckered in to being manipulated by him. Good for you! And you also, of course, want to help him if he genuinely needs it. I hope that a little internet research and using the nurse line can help you determine when that is.
