doctor, i have red colored skin on the right side of body. i mean not everywhere ..my right hand, chest , back , right side of head , behind ears, right thigh .... and my right hands and fingers r kinda swelled type...but left side is normal it is by birth itself while pressing on reddish place it turns white. In a cold atmosphere this red color turns dark purple. and i feel like that part is frozen..and cant do anything with right hand with force at cold times.. what is the reason for that now am 19years old
