“Should I be worried?”

Consult urgent care or pcp

Yellow liquid comes from skin abrasion. Keep it clean with antiseptic fluid such as alcohol, Betadine, peroxide, etc., and it will heal. As long as range of motion and muscle strength are normal, nothing to worry. Yet, there may be some pain and tenderness due to muscle/fascia strain. It can be resolved by light touch and hold, but not massage, stretching or exercises. Visit website: NoMorePainClinic.com for more information.

That is not unusual. Wash it gently with dial antibacterial soap 3 times a
day, then put neosporin ointment on it and cover with a big bandaid or
gauze. It will take a couple of weeks to heal.

Hope it helps!!!

I would not be worried, that's pretty normal for any open wound. The skin functions as a barrier to keep bad things out of the body, but also to keep fluid in the body. Whenever you have a break in the superficial skin layer like the abrasion you have on your shoulder, it's normal you have leakage of a clear yellow fluid coming from the wound. That's the normal color of your body's fluid (water mixed with some proteins and other stuff). It's also normal to have a little pink color around the edge of the wound, that's your body's normal inflammatory response as well. As long as the fluid doesn't turn into a thicker whitish-yellow fluid and the redness doesn't start to spread you should be fine. Just shower normally and clean it with soap and water, then apply a bandage to keep it clean and keep things from rubbing up against it. Of note, you might get a little layer of yellowish tissue on the wound, which is also normal. That's some of that protein sticking to the wound. Again just keep it clean and covered and it should do fine, especially for a 16-year-old.
