My left hand's ring finger and middle finger do most of the writing on my 'Write-hand' though I am right-handed. My right hand's thumb does the rest.
Yesterday my 'write-hand' was itching all day. Swollen and red in the evening. Today I went to show it to a doctor. He said it was erisypelas and gave me penicillin. I've had it before on my right leg and several times on my right arm, but never before on my hand. I haven't had the intensive pain I used to have with previous 'attacks'. I wonder if it really is erisypelas or something else.
