Unexplained White Coating on Tongue
Hello everyone. I’m 25 years old and identify as AFAB. Around two weeks ago, after a sexual encounter with a new partner where I performed oral sex, I noticed a peculiar white coating developing on my tongue, accompanied by unpleasant breath and a dryness in my mouth. Additionally, I've observed some red bumps and a scalloped appearance to my tongue. To ensure my health and safety, I visited Planned Parenthood. The doctors there didn’t suspect it was an STI, considering the timeline of my symptoms. They conducted an oral swab test, which came back negative. Then, I contacted my primary care physician (PCP) who also performed a swab to check for oral thrush. This test also resulted in a negative finding. Nevertheless, my PCP prescribed me a course of fluconazole, 100 mg for a week, and I’m currently on day six of the treatment. Despite diligently maintaining my oral hygiene routine, which includes brushing, flossing, and scraping my tongue, the white film remains stubbornly in place. I plan to follow up with my PCP soon, but I would appreciate any insights or opinions on my situation. My regular medications consist of testosterone, birth control (the progestin-only pill), and PrEP.

It sounds like you've been proactive in seeking medical advice about your concerns, and it's understandable to feel uneasy about the persistent symptoms on your tongue. Here are the main points regarding your situation:
-
Symptoms Management: The white coating, bad breath, and dryness in your mouth can be concerning, but since you’ve tested negative for oral thrush and STIs, it could be due to other factors such as oral hygiene, dehydration, or even an irritant related to your recent activities.
-
Possible Causes: The combination of symptoms you describe—white coating, bad breath, and scalloped tongue—could indicate a few non-infectious issues such as:
- Dehydration or Dry Mouth (Xerostomia): This can lead to bad breath and a white coating due to reduced saliva which normally helps cleanse the mouth.
- Irritation: Physical irritation from oral sex, changes in diet, or the use of certain medications can all contribute to these symptoms.
-
Treatment Status: Since you're on fluconazole and it generally takes time to notice a significant improvement depending on the condition being treated, it's important to continue with this course as prescribed.
Next Steps:
- Continue Fluconazole: Complete the full course of fluconazole, as it may still help address underlying candidiasis if present.
- Hydration: Increase your water intake to combat dryness. Aim for at least 8 glasses (64 ounces) a day.
- Humidity: Use a humidifier in your living space to help with dry mouth, especially while sleeping.
- Avoid Irritants: Reduce or eliminate tobacco and alcohol, as they can exacerbate dryness and irritation.
- Oral Care: Maintain your oral hygiene routine, but also consider using an alcohol-free mouthwash designed specifically for dry mouth or bad breath.
Follow-Up:
- Monitor Symptoms: Keep an eye on any changes in your symptoms, and note if they improve, worsen, or develop into new symptoms.
- Consult Your PCP: Discuss your concerns and ongoing symptoms during your follow-up appointment. If the white coating persists after finishing your medication, they may explore other causes such as geographic tongue, other fungi, or systemic issues.
Remember, taking care of your oral health is a priority, and you're already on the right path by seeking help. Let's hope for a positive outcome from your current treatment! If you have further questions or if things change, feel free to reach out for more guidance.

Interpreting My Holter Monitor Results
Hello all, I'm a 27-year-old female who regularly takes omeprazole and buspirone, but I don't have any diagnosed medical conditions. I just received the findings from my Holter monitor test and I'm feeling quite confused about what they indicate. Are the results positive, negative, or a bit of both? I’ve shared an image in the comments for reference, and I appreciate any insights! Thank you!
Injury at the Beach: My Son's Foot Incident
While at the beach, my son accidentally scraped his little toe against a rock, resulting in a cut. After we returned home and bathed him, we discovered that sand had become trapped beneath the skin of the wound. We had assumed the water would wash it away, but it seems some remains. I’m hesitant to try removing the sand myself, as even a slight touch causes him discomfort. Given that he’s just 8 years old, I want to ensure I don’t cause him any pain. What would be the best course of action? Would applying antiseptic cream and securing it with a bandage be sufficient? Thank you for your advice!
Diminished Sense of Smell
Throughout my life, I’ve noticed that my olfactory abilities have never been particularly sharp, even prior to the pandemic. At just 18 years old, I find it curious. My nasal passages aren't blocked, yet I struggle to detect most scents unless they are incredibly potent or I’m very close to the source. Does anyone have insights on what might be causing this and suggestions for improvement? For context, I’m a male, 18 years old, standing at 5 feet 9 inches tall and weighing 179 pounds.
What Tests Should I Consider?
For context, I’m a 31-year-old female weighing 130 pounds. I do not smoke and do not consume drugs or alcohol. My medical history includes diagnoses of Postural Orthostatic Tachycardia Syndrome (POTS), Benign Paroxysmal Positional Vertigo (BPPV), complex sleep apnea, arthritis with HLA-B27 positivity, and a recent MRI that revealed a lack of blood flow in the left sesamoid region. Current medications include Zoloft, Wegovy, Zofran, Zyrtec, and Tylenol/Advil. Recently, I experienced an unsettling episode. While turning my head to the right, which is my more rigid side, to speak with someone behind my desk, I began to feel a significant heaviness and fullness in my ears within half a minute, followed by dizziness. It felt as if I were on the verge of fainting, although I have only previously experienced lightheadedness related to my POTS. Could these symptoms be connected to my MRI findings or my POTS condition? What additional tests should I consider discussing with my physician?
Concern About My Son's Head Ridge
I recently gave my 4-year-old son a buzz cut and noticed a distinct ridge running along the top of his head. Throughout his early years, he had a thick head of hair, which concealed this feature, so we hadn't detected it before. This ridge wasn’t present during his infancy. Should I be worried about this development?
