Pain from the right side of my back moved to the hips. Please help.

Hi doctor,

I have pain in my hips. I began to have a slight ache on the right side of the lower back and then it got moved to my hip-deep in the socket like a toothache. I have had pain in my bones also for the past two days. Taking a hot water bath helped me and I was able to move around a little bit but still, I have pain. Sometimes, my knees get swollen and they become hot to the touch. This never happened to me before. I had a low-grade fever on and off. I have a couple of sores in my mouth and a couple of knuckles on my hands hurts a lot. I tested my RA factor before few months and everything was normal. I tested for lupus and the result came back negative. I have severe Raynaud's too. My urine smells a lot in the morning even after drinking plenty of water. A few years ago, I had knee swelling where I could not walk and the pain was incredible for a couple of days, and went away after a few days. My C3 and C4 were deranged and other values were normal.
