I'm in a similar situation. Are you in the US? Here, there's no way around pushing through to get out once in a while to see a doc. They won't keep you as a patient if you don't show your face once in a while. If you have a true emergency, you call an ambulance, but I've learned that what can be done in the ER is very limited these days. They will only treat actual acute emergencies. I've been sent home several times, even when I was so weak I could barely stand up, and was all skin and bones. The system has really changed in recent years.
Alternatively, I have sought out help via phone consults. Of course there's a limit to how far that can go in terms of treatment. Dr. Chia in Los Angeles does phone consults, but you need to get to a specialized lab (Quest or Labcorp) to get blood work done that he orders, before scheduling a consult with him. And he's not cheap.
Generally, I put a lot of energy into arrangements for getting physical support - people to help me get places that I absolutely have to get to. There are medical transportation services, which can be difficult if you're not feeling up to all the waiting, but good to know all the resources that are available. I do a fair amount of hiring private help for transportation, household chores, grocery shopping, etc. - more than I can afford, for sure, but that's another story. I have found a lot of resources through a social worker.
And I would say that I'm homebound, and it's not a good thing to push myself through the stress of getting myself out the door, not to mention dealing with hectic medical offices, but sometimes I just decide that the benefits outweigh the risks, on a case by case basis. And I haven't figured out a better way to get dental work otherwise!
Good luck, and let me know if you'd like more specifics about getting more support.
