Almost 2 months ago my 4 year old son fell outside and hit his cheek on the wood edging around my interlock patio. His face swelled up (scraped not cut) and has now been left with a small jelly bean like hard mass under the skin with discoloration under it. It impares his smile. Will it ever fully heal. My Dr. said it's a long process and it may not 100%. Any advice on how to get rid of it would be greatly appreciated. Thanks.
