Hi everyone, i have a question, For some reason im very very frustrated today...I have so many questions.. Maybe because its getting warmer outside and i want to go do the things i usually would do.....
What exactly causes the swelling? My hand last night and today is double the size and hurts SOOO bad today.. I just want to know what it causing it? IF i have RSD fine....But i still need to know what is causing the swelling? My knuckles are purple! Is it a circulation problem? If so is there a test for circulation? To see whats not working right? I was at the grocery store walking today and i looked at my hand and arm after being there for 5 mins and it was swollen and had white blotches all over hand and arm....It seems to me that the more i do things to move my shoulder the more swollen my hands get(which makes me want to believe the problem is with my shoulder?) uhgggg i cant take this
Does or can nerve damage cause swelling?
What causes bad circulation?
Can SOMEONE please help me?
