Remedies for Lips blisters 

If your blister came about while you had a fever and is still there after the fever is gone, you would need to consult a doctor to figure out exactly what it is. Any blister that stays after an illness could be a residual effect of the illness. This could also mean that your fever may have something to do with the blister, and may not have been an ordinary fever to begin with. The purplish dot you describe in the middle of the blister makes it sound like you have been bitten by something.

For most part, purple discolorations of any kind on the skin indicate that you have been bitten by a poisonous insect or spider. However, if this were true, the impact of the toxin would have been felt instantly, and you would have had an adverse reaction to it as well. In any case, if it is a bite of some sort, you can try to rub a piece of iron on it. In most cases of such blisters caused by insect bites, this remedy will help to remove the discoloration quite quickly. Do remember that it could be an insect bite of some sort which has left behind a blood clot as well.
