Doctor, My right pinkey finger has been swollen now for 2 weeks. Woke up one morning after cutting the lawn with a manual mower and it subsided a little, but then when I weeded my gardens all afternoon with my right hand with hearty weeds, the swelling returned big time and has spread down the side of the hand and towards the palm. It is worse in the morning, and when I use the mouse on the computer my hand becomes completely numb. The swelling is very bad today, and as I type this my findertips are becoming numb too. I am right handed. What caused this and what continues to cause this?
