I have osteoporosis of my lower spine and osteoarthritis in my knees. I went to a rheumatologist for the osteoporosis diagnosis, but decided to go somewhere closer when my knee kicked up (after I had worked at a job for two weeks in which I had to climb, lift, bend, etc). My knee never bothered me that way before, but it's letting me know it's there now! I'm wondering if it could be rheumatoid arthritis too because it's bothering me so much. I didn't work out today for the first time in forever. The knee was so sore yesterday that I actually felt physically sick too. Is that part of osteo? I'm wondering, if this were you, would you go back to the rheumotologist, which is an hour away, or just see the knee guy who saw me for the osteoarthritis. He is in sport's medicine and I think they are Orthopedic surgeons (although no surgery is even being considered). I will probably have another x-ray. I've been going to PT, and I've been working hard, really pushing myself, but that seems to have made it worse. It's to the point where even putting my shoe on causes a little twinge in the back of my knee. And it aches sometimes even when I'm sitting down. Any insight? I'm new to both osteoporosis and this osteoarthritis. I could use a little help on symptoms, treatments and doctors from anyone. Can the joint aches actually make one feel ill? Thanks in advance!!!
