Concerns About a Crusty Mole
Recently, I (23, female) observed that a mole on my upper arm has transformed to a darker shade and developed a crusty appearance. It appears to be worsening rather than improving. I am in the process of scheduling an appointment with a dermatologist. Should I consider this situation as typical, or is it a cause for concern?

It's great that you are being proactive by scheduling a dermatologist appointment for your changing mole. Changes in a mole, such as darkening and crustiness, can raise concerns, but a professional evaluation is key. Here’s what to keep in mind:
Main Points
- Changes in moles can be normal, but some changes may indicate issues.
- Tracking other symptoms is essential while awaiting your appointment.
Explanation
Moles can change for various reasons. Sometimes, they simply evolve due to hormonal changes or sun exposure. However, any significant alteration in size, color (especially darkening), or texture (like crustiness) can be a warning sign, particularly if these changes occur over a short period or if the mole becomes itchy or bleeds.
Moles that meet certain criteria, known as the ABCDEs of melanoma, are particularly concerning:
- Asymmetry: One half doesn't match the other.
- Border: Irregular or jagged edges.
- Color: A mix of colors or dark shade.
- Diameter: Larger than 6mm (about the size of a pencil eraser).
- Evolving: Changes in size, shape, or color.
Next Steps
- Keep a close eye on the mole: Monitor for changes in size, color, or symptoms like itching or bleeding. This information will be helpful for your dermatologist.
- Document your observations: Take photos of the mole and note the date when you first noticed the changes.
- Avoid irritants: Refrain from picking at or scratching the mole, as this could further irritate it.
- Prepare for your dermatologist visit: Write down any other symptoms you have experienced and your history with this mole (such as when it first appeared and any previous changes).
You’re taking a wise step by seeking professional help, and it’s important to remain informed and vigilant while you await your appointment. Let me know if you have further questions or concerns!

Concerns After Taking Boric Acid Suppository Orally
I accidentally ingested a boric acid suppository yesterday, likely in the morning or early afternoon. Shortly after, I experienced severe diarrhea, which I initially attributed to the energy drink I consumed earlier. My stomach felt uneasy throughout the day, producing numerous unsettling sounds. Realizing my mistake today while considering taking another suppository, I remember that each one is 600mg. Am I going to be okay? I'm a 22-year-old female, 5'2" tall, and weigh 120 pounds.
Unexpected Swelling at Toddler's Neck
A 3-year-old boy, who was born five weeks prematurely and has a history of gastroesophageal reflux disease (GERD), has developed a lump at the back of his neck, positioned near the hairline. This swelling was not present when he awoke but was noticed approximately two hours later. He is not expressing any discomfort, and the area does not feel warm upon examination. Additionally, he can move his head freely without any signs of pain. He seems to be behaving normally; however, he did have a minor rash on his abdomen upon waking. The family spent time at the beach yesterday morning. Should they keep an eye on it or consult his pediatrician regarding this? Further note: The lump is somewhat firm but not inflamed or discolored.
Concerns About Health: High Calprotectin Levels and Anxiety
At the age of 21, I find myself overwhelmed with fear regarding my health. My recent calprotectin test results were alarmingly high at 224, which has led me to schedule an appointment with a gastrointestinal specialist next month. Although my doctor noted that she would not have referred me to a specialist had I not exhibited such a high level of anxiety, I can't shake my fears. I understand that anxiety and stress can contribute to gastrointestinal issues, but the severity of my symptoms—mucus in my stool and diarrhea—has me worried. Worst-case scenarios have been mentioned, including Crohn's disease, which adds to my distress. Not too long ago, I underwent a blood test for the presence of blood in my stool, and thankfully the results came back negative. Despite this, I can’t help but feel plagued by doubts, wondering if perhaps there was an error in either the blood test or the stool test, leading me to fear that I might actually be suffering from anemia due to a bleeding tumor. To add to my concerns, there is no family history of colon cancer in my immediate relatives. There were a couple of family members who succumbed to cancers related to smoking and alcoholism (specifically throat and lung cancer), and a distant cousin who faced leukemia at a similar age to mine. Yet, the absence of direct cancer links in my family does little to quell my mounting anxiety.

Concerning Inward-Turning Foot
At seventeen, I find myself grappling with several health conditions; I’m managing postural orthostatic tachycardia syndrome (POTS), hypermobility, and adenomyosis, and I'm currently at a weight of 240 pounds. One of the most challenging issues I face is that my left foot turns inward. Although I can force it into a straight position, it feels extremely uncomfortable and causes me to lose my balance. This peculiar alignment has been present since my infancy, as it was first recognized when I was around two years old. I suspect it stems from birth, especially because there was no injury involved. In prior physical therapy sessions, my therapist merely described my condition as "inward-turned foot with no known origin," but I assure you, it isn't something I'm doing intentionally; that's simply the way my foot behaves. This issue has led to a noticeable limp. I’ve been advised to perform a towel exercise, attempting to maneuver my foot, but the results have been lackluster. I'm curious about what might be responsible for this problem. Is there a solution? The embarrassment of limping has become overwhelming; I often face ridicule, and I would gladly wear a brace for an extended period if it meant alleviating this issue. It truly feels odd!
