my arm and hand feel frozen

I had a stroke this past August as a result of a complex artery stent procedure. Initially I couldn't swallow my own saliva and had to have a feeding tube installed but was always able to walk albeit i do have some balance problems that i didn't have before. I can swallow now but food sticks in my throat. I have full functionality of all my limbs and can walk and drive since day of the stroke. I walk 3 miles (6000 steps) a day. The problems i have post stroke are swallowing of food (food sticks in my throat) and my right arm and hand feel frozen solid all the time although i suspect this is more of a brain illusion and my hand isn't really cold. I can wear a glove but doesn't help very much. I can still play the piano same as before but my hand always feels frozen. I have suddenly started clinching my teeth which is causing me headaches. I have been waiting forever to see a neurologist to get some medication for the frozen feeling in my arm which i think is causing me to clinch my teeth. I can't find any solutions when i google my symptoms that gives me encouragement for the future. Has anyone had the frozen hand & arm experience and recovered from it?
