Hi hpittypat, welcome to the board
. To start new threads do what you did to post your first one. if the questions are related put them together, but when they are of different topics make separate threads. Taape is right, you'll get more responses.
It seems that either your dr. isn't very informed about osteo treatment or he doesn't want to take the time to explain what to do. Maybe seeing a different dr. would be a good idea if this one isn't helping you. For exercise questions talk to a physical therapist or a fitness trainer trained to help people with osteo. With the kind of pain you have you sure don't want to do anything that will make it worse. Are you able to go for walks? Just going for regular walks is helpful, even if they are only a few minutes each several time of day.
I am not familiar with silica, but like you won't take the drugs now available. I do take a natural supplement called strontium citrate
that i order online. There are several of us on this board taking it. I've been taking it almost 5 years and have seen gains in my scores without any side effects. While you are researching options, please check it out. If you have questions i'll be happy to help. take care...phyllis
