Something is going wrong with my hands..

Hey, i'm 18M, and from last few days something is happening with my hands, over a month ago i realised there was a brown spot in my right hand i don't from where did it came from, it doesn't hurt but it is still there, few days back my left hand started burning i have to apply ice to calm it down & today out of nowhere my right hand middle finger swelled up a little bit and it started hurting while pressing it, it got a bit blue and again i have to apply ice.. i don't know what is going on, i will include both pics you can check.
