Help, Bunions?

My 73 yr. old Dad, alzheimer's victim, has these hugh pockets of fluid, yellowish in color, with bright red centres, almost like a hugh (two inch) pimple right on the ball of his big toe(s). Right side is slightly worse than left, but both look very sore. He can barely walk, and is angrier than a bear who was interrupted from hibernation.  I have taken him to the doctor twice. The first visit, the doctor looked at his feet and said "he needs special orthotics, but since you can't afford that, I'll call drugstore and order special insoles". They ordered the insoles, next day I got them, he tried them on, grumbling cause they cost $17.00, and when I asked how it felt to walk, he said ä " little better".  So, the following week he was scheduled to have a squamous cell carcinoma frozen on his upper ear, so in we go. The Doctor (who actually seems afraid of my Dad), flew into the room with this little cup of nitro and dabbed Dad's ear for a minute and ran out saying, make an appt. in two weeks for the second nitro treatment. Erstwhile my dad was struggling to get his shoes off, I explained to Dad the Doc couldn't look at his feet that day cause he was running from examining room to examining room, dabbing nitro on a bunch of people, and of course the nitro was evaporating at room temperature. As the doc flew by me, I said "so we'll make an appt. to have his feet looked at?" The doctor tossed back over his shoulder "we already dealt with his feet, make an appt. to do the second freezing on the ear." So either this doctor has an aversion to feet, or he doesn't think people over a certain age should be using up precious scarce medical resources, or he's afraid to tell Dad what I discovered in my research, that bunions are here to stay, there isn't much you can do but cushion them, or what, but in addition to having to care for a declining toddler, who thinks he's running the show, I now have to live with an angry bear. The thing is, if I take him with me, when I go for groceries, etc. he has a fit waiting in the car. He refuses to accompany me into the store, bank, etc. If I tell him he needs to wait at home with my cell number taped to the phone, first he has a tantrum about me going out and not inviting him to come, then he calls friends and neighbors and tells them I've left him, I've been gone for six days etc. What fun. I think I have help coming early next week, my son is talking about coming and staying a while. But back to the bunions, anyone have any info as to how to treat these? Make him more comfortable, anything. As it is right now, he can barely walk. Next step will be a wheelchair if we can't get his feet healthy again. My Dad, the farmer, and woodsman who used to haul logs out of the woods on his back, in a wheelchair? I cant even begin to fathom that concept. Thank-you for bearing with me through this long description.

Thank-you. I'll call his doctor and see if he'll make a referral to an orthopaedic surgeon.

Thanks again guys. My Dad's feet are terribly important. He would not tolerate a wheelchair.
