I was pruning my rose bushes yesterday and was stuck through my gloves. I did not realize until I came inside to shower that I had a brown piece of the thorn in my knuckle on my index finger. I was able to remove the portion of the thorn with tweezers, within 3 hours my knuckle began to become swollen and painful. Now, this morning it is extremely swollen down into the second joint in the index finger and is swollen and hot to touch on the knuckle radiating onto the top of my hand. it is extremely tender to even bend the finger. please advise
