I have pain in all three.
First it started with my knees, they're al swollen, red etc.(Started with tendons first but now joints)
Then my shoulders, the joint itself, the tendons, shoulderblades and the muscles near the neck.
And then my elbows would hurt a lot, mostly the tendons.
But now it has spread out to the joint that are red too and quite swollen+tender to touch around it.
My pelvis-hips have been hurting a long time but now it has really spread out to the hip joints itself.
It was very stiff my Rheumy said when I saw him on tuesday.
The pain radiates to your tigh pretty much aswell.
And it hurts to lay on your sides or sit too long.
Other than that: Ribs, hands, fingers, ankles, feet, toes, lowerback, jaws etc
