Understanding Blister Fluid
Recently, I experienced a burn at my workplace, resulting in the development of a blister that later burst. The fluid that escaped was mostly clear, with a subtle yellow tint, and emitted a very faint aroma — it wasn’t overpowering or unpleasant, merely reminiscent of liquid from a biological source. While researching proper blister treatment on the internet, I encountered information stating that blister fluid typically lacks any smell. Should the fluid from a blister truly be entirely scentless? Or is it common for there to be a slight, non-offensive odor?

It's understandable to be concerned about changes in your blister fluid, especially after a burn. The fluid inside blisters, which is called serum, is typically clear or slightly yellow and can indeed have a subtle, non-offensive odor.
Main Points
- Blister fluid can have a slight smell, which may be normal; it’s often related to the body's healing process.
- The color and faint odor do not immediately indicate an infection or issue, especially if you're not experiencing other symptoms.
Explanation
Blisters form as a protective measure when the skin is injured, allowing serum to collect under the surface. While this fluid is usually clear, if a blister bursts, the serum may mix with other substances from the skin or environment, resulting in a slight yellow tint or faint smell. This is generally not a cause for concern unless accompanied by other symptoms like increased redness, swelling, or pus.
Next Steps
- Monitor for Symptoms: Keep an eye on the area for increased redness, swelling, or any signs of infection (e.g., pus, worsening pain, or fever).
- Keep the Area Clean: Gently clean the area with mild soap and water to prevent infection. Avoid using harsh chemicals or ointments that are not recommended for blister care.
- Cover the Blister: If the blister has burst, consider applying a sterile bandage to protect the area and promote healing.
- Practice Good Hygiene: Regularly wash your hands and avoid touching the area to minimize the risk of infection.
If the fluid becomes distinctly foul-smelling, or if you develop other concerning symptoms, consider seeking further evaluation. Your health and comfort during healing are important, so don't hesitate to reach out if anything changes.

Duration of Elevated Fecal Calprotectin Post-Infectious Colitis
Subject: Male, Age 28 Height: 180 cm Non-smoker In late February to early March, I experienced a viral case of infectious colitis. The most notable symptom was bloody diarrhea, which persisted for about two weeks, albeit with no associated pain. This issue suddenly ceased, and as of today, July 8, I have been free from symptoms for the past four months—no blood, no diarrhea, nothing alarming. However, I've noticed my digestive system has been more active than usual, particularly when I need to use the restroom or upon waking up. Aside from this, my stool appears to have returned to normal, with a mix of type 4 and occasionally a softer type 5, yet I have not experienced the severe looseness associated with type 7. During my acute illness, I had my fecal calprotectin levels measured on March 8, which were quite elevated at 2200. A follow-up test on April 24, completed 6.5 weeks later, showed a significant drop to 229. The confusing part arises with a subsequent test conducted on July 2—this measurement returned a value of 261, using a different lab with distinct cutoffs compared to the earlier tests. I am uncertain whether this level should be a cause for concern. I've encountered various sources online indicating that calprotectin levels can remain elevated for some duration after the cessation of symptoms. What is the typical timeline for these levels to return to normal? Can it possibly take months or even up to a year? Additionally, I wish to note that about three weeks prior to my July 2 test, I experienced a mild bout of food poisoning from June 8 to June 10, which involved vomiting and diarrhea after consuming contaminated food while traveling. Could this incident be linked to the 261 calprotectin result? I am eager to move on from this unsettling experience and would prefer not to continue stool sample testing. I am seeking reassurance, especially since I am not currently under the care of a physician (living in Canada, the situation is complicated).
Discomfort and Swelling in Left Nipple: A Concern
About five nights ago, I observed that my left nipple had become swollen and sensitive when I touched it. I also noticed a yellowish crust, often referred to as a scab or hardened plasma. Currently, there is notable inflammation and discomfort, but no signs of bleeding or discharge are present. I felt it necessary to share my situation, especially since the appearance seems concerning. I’m hopeful that it’s not a serious issue. For context, I recently discontinued finasteride, suspecting it might be linked to gynecomastia symptoms. Medications I’ve been taking include 1mg of finasteride for hair loss over the past year. Additionally, I have been on Telmisartan and metformin for a much longer duration. In terms of my recent activities, I have engaged in sexual activities, which included a partner stimulating both of my nipples.
Concerns Regarding Hemorrhoids and Anal Fissures
I’m sharing my experience in hopes of finding some guidance. About two and a half years ago, I developed issues with an anal fissure and hemorrhoid, which haven’t resolved. I’m a 22-year-old male, and these problems arose from anal intercourse. The hemorrhoid has now manifested as excess skin that is apparent externally, while the fissure is primarily on the inside. Occasionally, it bleeds and results in persistent discomfort, characterized by pain and itching. I have consulted a colorectal specialist on two occasions. During both visits, the doctor advised against surgical intervention due to the fissure’s location near the perineum, indicating that surgery might lead to increased pain. Instead, he recommended topical treatments to ease the symptoms, but unfortunately, they have not proved effective for me. I’m reaching out to see if anyone else has dealt with similar issues and what steps they have taken to manage them. This situation is something I think about every day. Do you think it would be wise for me to seek a second opinion from another physician? I can’t help but worry about whether this condition might affect my future relationships or sexual experiences.
Is the Understanding of POTS/Dysautonomia Becoming Obsolete for Healthcare Professionals?
As a 19-year-old woman who received a diagnosis of POTS (Postural Orthostatic Tachycardia Syndrome)/dysautonomia approximately one year ago, my journey has involved numerous evaluations by various cardiologists who tried to determine the root cause of my symptoms through trial and error. Ultimately, it became clear that POTS/dysautonomia was the most viable explanation for my ongoing issues. I experience persistent tachycardia, significant fluctuations in blood pressure, shortness of breath, along with feelings of lightheadedness and dizziness. Fortunately, I have yet to lose consciousness, thanks in part to some medications that help maintain my blood pressure.
Recognizing When Tonsil Stones Are Worrying
As a 21-year-old female, I’ve been dealing with tonsil stones since I was 16. However, over the past year, I’ve noticed that these stones have been getting larger and increasingly bothersome. While they aren’t painful, I often feel their presence at the back of my throat. Typically, I’m able to remove them fairly easily with the help of a water pick or a gentle q-tip. Unfortunately, their size is becoming a challenge, making removal more difficult. Should I reach out to an ENT specialist for advice, or are there some effective home remedies I could explore?
