hi, 3 days ago I fell and scraped the lower Palm of my hand close to my wrist. I didn t wash it but I put something pre applied on a cloth to clean it. It dried up with yellow stuff in the cracks. Today on Monday my school nurse checked it out and put something on it with a band aid ( most likely neosporin ). Then during gym I hit a volleyball which also hit my wound. After that whitish yellow gooey stuff formed and now I m sitting at home wondering what it is. There s a little red around it but no streaking.
