What Causes Itchiness And Stiffness In The Joints Of The Hands?

I HAVE ITCHING IN THE JOINTS/BONES OF BOTH HANDS. JOINTS INVOLVED ARE MOSTLY LAST JOINT AT TIP OF FINGERS AND THE AREA WHERE FINGERS JOIN PALM OF MY HAND. ALSO TINGLING AND STIFFNESS. NO REAL PAIN, BUT THE ITCHING IS EXTREME. I ALSO HAVE RECENTLY HAD TROUBLE WITH SWALLOWING FOODS AND PAINFUL SWALLOWING WITH SOME FOODS. IT S LIKE THE FOOD SEEMS TO GET STUCK AND THE PAIN IS AWFUL. SOMETIMES LEADS TO VOMITING. WHEN I SLEEP, IT SEEMS LIKE MY MOUTH SECRETIONS ARE BUILDING UP IN THIS POCKET IN ESOPHAGUS. I HAVE TO GET UP TO COUGH/CLEAR IT. MY FAMILY HAS HISTORY OF GOUT, BUT I VE NEVER BEEN DX WITH IT.
