2 weeks ago I got a thorn in my knuckle. I pulled it out and a pain shot across my knuckle. It was very red, hot and swollen. The day after I went to the Dr’s who put me on anti biotics for a week, flucloxacillin. The swelling and redness reduced. Now it is slightly swollen with a lot of pain in the joint of my finger, all around it, where I touch the knuckle, or use my hand , I feel. It . How long might this pain last ?
