Even if it ends up NOT being ankylosing spondylitis exactly - you should know that there are some hereditary factors that predispose to AS but also to other, similar conditions which are collectively called “inflammatory spondyloarthropathies.” Given your brother’s diagnosis you probably have a higher chance of one of these conditions because of your shared genetics. So yeah absolutely ask another physician until someone investigates your symptoms!
It’s really interesting to me that you have provided this additional clue because ankylosing spondylitis was literally the first thing that popped into my head reading your story. I agree with others that your story sounds much more than typical aging symptoms and you should seek the opinion of another physician.
Seriously need some other options. I think Dodge’s upcoming Ramcharger looks promising and I’m surprised more truck manufacturers haven’t tried to design vehicles that are electric with a generator backup to extend range. Come on, Ford. I would say come on GMC but they took out CarPlay.
No going off-grid is a substantially larger investment than most people can afford. To be off grid you have to be able to make enough electricity even on cloudy, short winter days. That means your system must be massively oversized for your needs during most of the year. You also need adequate batteries to store energy for overnight.
Instead people get enough solar to offset some or all of the electricity they use - but on average over time. So they produce a ton during the day and then draw from grid at night.
