Assessing the Healing of a Cut Knee: Is It Improving or Infected?

7/14/2025, 11:01:08 PMMale25-34

In my late thirties and weighing around 280 pounds, I recently experienced a mishap while walking at night. After it had rained, I slipped in some muddy areas that had overflowed onto the sidewalk while wearing flip-flops, resulting in a scraped knee against the concrete. To tend to my injury, I did my best to clean the area using a can of diet soda—my only available option at the moment—before making the mile-long journey back home. Once there, I thoroughly washed the wound with soap and water, applied some rubbing alcohol for additional sanitization, and placed a bandage over it. Thankfully, I did not experience any bleeding. That night, I felt a burning sensation. The following day, I purchased larger bandages and some antibiotic ointment, a generic version of Neosporin. The first photo I took shows the condition of my knee approximately fifteen hours after cleaning and bandaging it. By the second night, the discomfort had decreased, and by the third, it was barely noticeable. My dressings have shown minimal fluid buildup. The second image, taken two days after the first, reveals that some skin patches have turned a dark red, which has raised concerns for me. Despite this, I have not observed any other signs of infection. The redness seems localized to that specific area, showing no signs of spreading, and I have felt no heat accompanying it. Is the recovery process proceeding well, or is a visit to a clinic warranted? I currently do not have health insurance, which makes seeking medical assistance a bit challenging.

It's great to hear that you are taking care of your knee, and I understand your concerns about its healing process. Based on your description, it seems you are making progress, but let's break it down further.

Key Points:

  1. Current Condition: The localized redness and reduced discomfort you mentioned suggest that your injury may be healing well overall. However, the dark red patches could be concerning for infection or irritation.
  2. Signs of Infection: You mentioned that there are no spreading signs of redness, heat, or other major symptoms, which is a positive sign.

Explanation:

Healing from a scrape like yours can vary, and some redness is normal as the skin repairs itself. The absence of pus, increased pain, fever, or spreading redness are good indicators that an infection may not be present. However, dark red patches can sometimes indicate irritation or early infection if they worsen.

Next Steps:

  1. Monitoring: Keep a close watch on the redness. Observe if it changes in size, spreads, or if you notice any discharge. Jot down your observations daily.
  2. Care at Home: Continue to clean the area gently with mild soap and water, apply a thin layer of the antibiotic ointment, and cover it with a clean bandage at least once a day. Avoid soaking the area in water (like baths or swimming) until it fully heals.
  3. Pain Management: If discomfort arises, consider over-the-counter pain relievers like acetaminophen or ibuprofen (if you have no contraindications or allergies).
  4. Seek Help if Needed: If you notice any increasing redness, swelling, or if the pain returns, it’s essential to find a way to get medical attention. Local clinics, urgent care facilities, or community health centers may offer services on a sliding scale based on income.

Remember to take it easy and avoid activities that may irritate your knee further while it heals. You’re doing a good job caring for your injury, and monitoring it closely will help you stay on top of your healing. If you have any more worries or questions, feel free to ask!

Strange Jelly-Like Substance Observed from Wound

I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.

Strange Stomach Sensation Leading to Waking Up

Greetings. I'm a 36-year-old male, standing at 172 centimeters and weighing 90 kilograms. I don't take any medications, nor do I smoke. I've been living with diastasis recti for several years now, and I may also have irritable bowel syndrome (IBS). Additionally, I deal with fatty liver and kidney stones, though I assume these last two conditions are not related to my current concern. Occasionally, I experience a peculiar sensation that jolts me awake; it feels like a quick pulsing in my stomach. I’ve noticed it tends to affect the left side when I’m lying on my left side and the right side when on my right. Remarkably, it can occur even when I’m on my back. This strange feeling often escalates into a surge that fully rouses me. Alongside this, I sometimes feel prickling sensations throughout my body and fleeting lightheadedness. When this sensation disturbs my sleep while I’m turned to my side, shifting onto my back or the opposite side might alleviate it, but not always. In instances where I awaken while lying on my back, I discovered that gently pressing my hands on either side of my stomach can help, as can rising to a sitting or standing position. However, during my last two episodes—one a couple of weeks ago and another tonight—those techniques weren’t effective right away, which made me feel a bit anxious, prompting me to seek advice. Does anyone have insight into what might be going on? By the way, I’ve undergone routine ultrasound examinations of my abdomen by two different physicians during check-ups, both of whom assured me that everything appears normal, including my abdominal aorta and internal organs. They didn’t identify any issues at that time.

Understanding Tuberculosis Exposure Risk

A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.

24M | Unexplained Fainting Incident

**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?

Healing Progress Post-GBS: Toe Concerns

I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
