I have lower back pain, itching all over, frequent fevers, im loosing weight without dieting, deformed hands, lower spine intensive pain. Trouble walk?

Needs workup. Boy, it sounds like you've have a lot of issues that have come up. I would see your physician this week. Many things will need to be looked into including infection, inflammatory conditions (i.e. Autoimmune diseases), and malignancies. Please get help and good luck.
Go to ER. If you are having all of these symptoms at once i would visit your physician or the er as soon as possible.
See your doctor. asap as you need a full workup to sort out what is going on. Cannot be done over the internet.
