I feel for you. Doctors are horrid, and they often know little about the drugs they prescribe. They often neglect your mental health needs too. I am very small too, under 100lb, and feel the doses they prescribe as universal is just not sound science. It makes zero sense to me. Every time I get a pill prescription I need half or quarter the dose....why not injections too? Every women at the same age is not the same height, weight, body type, etc. Hopefully pain management avoids steroids (which weaken bone/tissue). I turn a lot to more natural medicine as a last resort: herbs, supplements, foods, exercise. It takes some research though, and finding a knowledgeable naturopathic doctor. DO medical doctors also sometimes have more background in natural methods than MDs. I am on standard govt. Medicare for disability, and it works great, and they rarely deny anything. It helps to have state Medicaid too, if you are lower income. I have heard, but you may wish to research yourself, that "advantage" programs are not real Medicare, but private insurance using the Medicare name...you may want to look into getting away from that back to regular Medicare, though I've heard also this is hard, because the private companies make it hard.
