Your baby is rather young to be dewormed but the usual time is said to be when children start playing outside in sand especially when dogs and cats are around.So you can start now if you are concerned.
Any foreign object even something as small as a splinter can introduce infection. I am concerned about the fact that his nail is lifting off. Are you sure that there is no sign of redness or swelling which would indicate an infection is starting up? In any case it would be best if your baby was seen by your doctor just to sure that all is well.
