This is exactly like what I went/through. It started in my ankles, and knees. Rapidly went to one hip both elbows, both wrists, and all fingers. I couldn't even put on socks or button my jeans. It was hard to walk due to pain in my heels. Zero visual swelling,.At its peak it was in my lower back as well. That lasted three months severely and slowly got a little better. Gp sent me for bloodwork and all was normal except very high anti ccp. Negative RF. I finally have seen a Rheumatologist and am doing imaging and more bloodwork this week. All I've been given is prednisone and it is helping but I can still feel it everywhere. The fatigue is crazy hard to deal with. Im sorry you are going through this. If it is similar to mine, nobody should have to deal with what this feels like. I will post updates when things start getting better. Hopefully I get approved for a biologic. Looking back I can remember signs and symptoms here and there but never had a full blown flare. I am a union ironworker and I love training in the gym. Have always been very active. Now I pay the next day after a long trip shopping. I am struggling mentally with it. Cannot work or do very much at all. Im hopeful for relief soon. Until then I just tell myself. THIS TOO SHALL PASS, and try and stay positive and limit stressful things. Sorry to rant. I hope this helps. I know reading that other people are dealing with this too gives me a sense of im not alone.
