Had a dwelling in index finger right side to the nail, with a small greenishness. Met a doc, got antibiotics. Didn't help and under lot of pain one day, had to burst the swelling and green pus came out. Later it healed itself and old skin came out with new skin developing. Now again during new skin development phase, swelling has started again. The cause for earlier swelling was nail-biting as per doc and maybe again it could be the same cause, however I was cautious not to do so. No greenishness is visible this time so I have no area to burst to take ur fluid inside swelling. Am taking antibiotics again but use. The time period between earlier swelling and this swelling is roughly 1.5 week now.
