Scraped Knee: Healing Process or Infection Concern?
As an adult, I found myself in a rather embarrassing situation after a night out. While rushing to catch a bus, I stumbled on an uneven sidewalk while wearing my Target sandals, leading to a nasty fall that left my knee scraped up pretty badly. I was en route to the park with a friend when I realized I had my first aid kit tucked away in my bag, but it took me about a half hour to get to it. When I finally tended to the wound, the process was quite painful, which makes me doubt I cleaned it properly. After spending half an hour outside before applying a bandage, it’s now been two days, and my knee is in significant discomfort. Initially, my first bandage soaked through with blood, and after changing it to a new one, I noticed a yellowish substance and what appeared to be pus forming. While there’s no foul smell, the wound is discharging a distinct greenish-yellow fluid, and bending my knee continues to be incredibly painful. Should I seek urgent care, or is it safe to assume that my knee is on the mend?

It sounds like you're dealing with a scraped knee that may be showing signs of infection. With symptoms like discomfort, yellowish discharge, and pain when bending your knee, it's crucial to assess the situation carefully and take appropriate steps.
Understanding the Situation
After a scrape, it's natural for wounds to ooze a small amount of fluid, but increased discomfort, significant discharge, and a color change might suggest an infection. The greenish-yellow fluid you mentioned often indicates the presence of pus, which can be a sign that your body is fighting off an infection.
Next Steps
-
Keep the Wound Clean:
- Gently clean the area with mild soap and water to remove any dirt and bacteria. Pat it dry with a clean towel.
-
Apply an Antiseptic:
- After cleaning, apply an over-the-counter antiseptic ointment like Neosporin to help prevent infection.
-
Re-bandage Properly:
- Use a sterile bandage to cover the wound. Change the bandage at least once a day or whenever it becomes wet or soiled.
-
Monitor Symptoms:
- Keep an eye on the wound for any worsening symptoms, such as increased redness, swelling, increased warmth, or a developing foul smell.
-
Pain Management:
- Over-the-counter pain relievers like ibuprofen or acetaminophen can help relieve discomfort. Follow dosing instructions on the packaging.
-
Consider Seeking Care:
- If the pain becomes severe, if the discharge increases, or if you start to feel unwell (fever, chills), it’s essential to seek urgent care. This is particularly important if the infection appears to spread (redness expanding around the wound).
Conclusion
While some discomfort and mild discharge can be typical after an injury, your symptoms suggest you should monitor your knee closely and maintain proper care. If there’s any increase in severity, don’t hesitate to seek professional care. Remember that taking care of yourself is important, and getting timely help can prevent complications. If you have any further concerns or changes, feel free to ask!

Am I Overreacting?
Recently, I had an unfortunate accident where I (25F) banged my head quite forcefully against a doorknob. It happened on a Thursday; I was in a squatting position picking something up and stood up abruptly, hitting the knob right on my right temple, close to my eye. The impact was so intense that I fell backward onto the floor, landing on my backside in pain. The aftermath was a severe headache, followed by feeling extremely nauseous the next day. I hesitated to go to the emergency room because I thought it might sound ridiculous to seek help for a doorknob injury, so instead, I opted for urgent care. The medical staff conducted an evaluation and assessed that I appeared to be fine, providing me with a pain relief injection. Unfortunately, that shot didn't offer much relief; my headache persisted, and I continued to experience waves of nausea. Compounding the situation, I also deal with significant anxiety, which has heightened my distress throughout this experience. My headaches intensify in chaotic environments, and it has now been two full days since the incident. I'm left wondering, when will I start to feel improvement? Is it concerning that I’m still feeling so unwell?
Infant Diagnosed with Congenital Heart Anomaly
I have a nine-month-old son who was born prematurely at 33 weeks in Colorado. While in the specialized care unit, he developed an occasional arrhythmia that did not present consistently. Follow-up EKGs revealed it was absent at times. Additionally, an echocardiogram conducted a week after his birth indicated the presence of a small atrial septal defect (ASD). We were advised that there would be no need for another echocardiogram until he turns two, at which point they would check to see if the defect resolves itself. This seems like quite a long period to wait, but I didn’t voice my concerns. Given the lengthy waiting periods for pediatric specialists in my state, I wonder if that influenced their recommendation. Are there any doctors here experienced with managing follow-ups for small to medium ASDs? Should we really just monitor for two years to see if it closes? Is there a possibility that it could worsen?
Concern Over Skin Rash
Hello, I'm a 22-year-old female and fully vaccinated. I’m currently on a variety of medications, so please bear with me: Lamictal (100mg), Clomipramine (75mg), birth control, Dicyclomine (10mg taken four times daily), Rabeprazole (20mg taken twice daily), Vitamin B12 supplements, and Flintstones bone health vitamins. I've also been treated with Doxycycline (unsure of the dosage), transitioned to Bactrim, and then switched to Prednisone after discontinuing Bactrim. In terms of mental health, I have diagnoses of Borderline Personality Disorder (BPD), Generalized Anxiety Disorder (GAD), and Major Depressive Disorder (MDD), along with gastroparesis. Each day, I spend a significant amount of time outdoors, usually about an hour in the woods. I first noticed a rash on June 9th, which resembled either mosquito bites or poison ivy, quite possibly due to my frequent outdoor activities in a nature preserve. After it worsened, I sought treatment at urgent care, where I was diagnosed with contact dermatitis and advised to use hydrocortisone. However, the condition continued to deteriorate, beginning to weep slightly. Concerned about the spreading rash, I returned to urgent care, and they suspected it might be impetigo, prescribing Doxycycline. After three days of taking Doxycycline with no improvement, I visited urgent care again, where the doctors expressed their concerns and prescribed Bactrim along with Prednisone. Despite following up two days later due to the worsening and spreading nature of the rash to other parts of my body, the urgent care doctor suggested the possibility of antibiotic-resistant bacteria and referred me to the hospital. After spending five hours at the hospital, the assessment was less alarming; they attributed it to either contact or atopic dermatitis and recommended a steroid cream while discontinuing the antibiotics but maintaining the Prednisone. I haven’t procured the steroid cream yet, and I'm hopeful it will provide relief. However, my anxiety persists due to the urgent care's alarming comments about potential MRSA requiring IV antibiotics. Thank you for taking the time to read my situation, and I apologize for the poor formatting, as I've been navigating this on my mobile device.
Three Years Post-Cesarean: Struggling with Rash
I’m a 35-year-old female, standing at 5 feet 5 inches tall and weighing 200 pounds. I've never smoked and have no additional medical concerns at this time. For the past three years, I have been grappling with a rash located on my pelvic area following my cesarean section. About a week post-surgery, I routinely lifted my abdomen to check my incision. To my horror, I discovered a vivid red rash that was not only oozing but also emitted a foul odor, leading me to suspect an infection. In a state of distress, I reached out to my OB-GYN, who managed to fit me in for an appointment swiftly. Upon examination, they reassured me it likely wasn’t an infection but rather a yeast infection. I was prescribed a powder to use until my incision was sufficiently healed to apply a cream. Unfortunately, just when it seemed to improve, the rash would return, often more aggressively, as evidenced by the condition in various photographs I’ve taken over time. In my search for relief, I have experimented with an array of treatments, including medicated powders and creams, hibiclens for cleansing, methods to maintain dryness, diaper rash ointments, rubbing alcohol, and witch hazel. Despite my numerous efforts, I feel overwhelmed and desperate for a solution. Any advice or assistance would be greatly valued. 😭
