[|Human|] My son scratched his shin (almost length of shin) on a plastic resin chair back in May.  It was very bloody and deep in some areas.  It healed with with the only scaring being redness where the scabs formed.  Now he is developing fluid filled areas on the scar.  Is this normal?  could it be an infection starting?
[|AI|]  Dear sir, HiT hanks for posting your query on Chat Doctor. I appreciate your concern for your sons' problem. I am of the opinion that it is an exaggerated response of healing referred to as Keloids. When skin is injured scar tissue forms over the wound to repair and protect the injury. In some cases, scar tissue grows excessively, forming smooth growths called keloids. Usually they are not harmful but may cause cosmetic concerns hence do not require treatment because they tend to shrink and become flatter over time even without treatment. You can apply a moisturizing cream to keep the tissue soft. If growth continues or if he gets pain or itching, you may visit a dermatologist for possible use of Corticosteroid injections to reduce inflammationCauterization (cold) Freezing the tissue to kill skin cellular treatments to reduce scar tissue Hope your query is being answered. Kindly rate the answer, if you are convinced. Regards
