I have pretty much had the same issues as has been mentioned in the comments so far! This past summer, I began having stiffness and pain in my hips and waist. I just thought it was age related and being 65 and very active, normal aging stuff. I would take ibuprofen and that helped. Things progressively got worse and within a month, the pain began to migrate to my shoulders, neck upper arms. I began to realize this was not normal. I dreaded getting out bed, out of a car, a chair, bending over to pick something up, stuff like that. Especially bad in the morning, but would improve slightly during the day. I ended up seeing my doctor about 3 months after initial symptoms. This was in late October! I was in excruciating pain at the time! He diagnosed me with PMR and placed me on 10mg of prednisone. Within a couple of days, I was pretty much pain free and feeling amazing once again. I even had lots of my flexibility back. Off and on sense, I have had my prednisone decreased and increased based on symptoms. About a month later, I began having headaches that would not go away and jaw pain. Tylenol arthritis at 650mg helped, but only for a few hours, at least I could get some sleep! I then began having double vision occasionally. My rheumatologist, placed me on 60mg prednisone, up from 40mg. There is a good chance I have GCA, jaw hurts while chewing and stuff! I see my rheumatologist again tomorrow morning to go over options. My rheumatologist advised 3-4 weeks ago to get a temporal cell biopsy done. I went to a vascular surgeon last week in Dallas and he advised against it since I have been on prednisone for so long. We will see what happens tomorrow. This high dose of prednisone that I take in the morning really begins to make me feel terrible about 30 minutes later and for the next 7 hours or so. So much fatigue, light headed and brain fog. Good luck with your condition and hopefully it won't progress like mine has. Knowing that over time things should improve helps! This forum has helped me a lot also!
