my dad got what he thinks was a thorn stuck in his finger a few weeks ago, after suffering for a while he went out of hour docs as the area between the finger nail and the middle joint of the finger was very swollen and sore, so much so the pain was keeping him awake at night, he was given AB's, they took most of the paina way but it remained swollen, now today the pain is back and kept him awake last night, his finger is swollen and very hot to the touch, after much convincing he says he will go the doc tomoz now my question is, what will they do? theres obviously something stuck in there isnt there? (even though there is no head or opening at all around the affected area)
