Persistent Dry Mouth Challenges
Hello Doctors, For the past couple of months, I've been experiencing an ongoing sensation of dryness in my mouth. It's not just simple thirst but rather a pervasive lack of moisture. I have ruled out diabetes; my fasting glucose levels are at 68, with a non-fasting result of 96. Additionally, there’s no indication of insulin resistance, as my fasting insulin level is recorded at just 3.1. My A1C level stands at 4.6, and a recent test for Sjögren’s syndrome returned negative results. What other possibilities should I consider? Interestingly, I've noticed that the dryness tends to diminish after I eat, but it returns swiftly, typically within 15 minutes. I make a conscious effort to stay hydrated by drinking plenty of water, and I sometimes incorporate sugar-free electrolytes into my routine. Furthermore, tests for magnesium, sodium, and potassium levels have all been normal. Occasionally, I also experience mild jaw discomfort, perhaps once a month, localized just beneath my jawline, but that’s about the extent of my symptoms. I visited the dentist recently, where I had all dental cavities treated, and no significant issues were identified during that appointment. Moreover, while my saliva production appears to be normal, the sensation mainly affects my tongue and the walls of my mouth—if that distinction helps clarify things. A little about me: I'm a 27-year-old male, standing 6'2" and weighing 160 pounds. I do not smoke and only drink socially. I’m not currently taking any medications. I appreciate any insights you might have regarding this condition. Thank you!

Main Points: Persistent dry mouth (xerostomia) can be frustrating and may arise from several factors other than the common conditions you’ve ruled out. Let's explore some potential causes and actionable steps you can take to relieve your symptoms.
Explanation: Dry mouth can be caused by various factors, including dehydration, oral habits, or other underlying conditions not related to diabetes or Sjögren’s syndrome. Since your saliva production seems normal and the dryness decreases after eating, consider other influences such as:
- Environmental Factors: Dry air or certain environments can contribute to dryness in the mouth.
- Diet: High salt or spicy foods can exacerbate dryness.
- Oral Habits: Mouth breathing, especially during sleep, can lead to a dry mouth.
- Nerve Function: Sometimes, nerve function related to saliva production can be affected, leading to a sensation of dryness even if production is adequate.
Mild jaw discomfort can also indicate tension or occasionally clenching your jaw, which might contribute to your dry mouth as well.
Next Steps:
-
Hydration: Continue to drink plenty of fluids, especially water, throughout the day. Try incorporating more hydrating foods, such as fruits and vegetables.
-
Environmental Adjustments: Use a humidifier in your home, especially during dry seasons, to add moisture to the air.
-
Chewing Gum: Try chewing sugar-free gum or sucking on sugar-free candies to stimulate saliva production. This can help manage the dryness between meals.
-
Breathing Habits: If you suspect you might be breathing through your mouth, especially at night, practice breathing through your nose during the day, and consider discussing potential solutions for nighttime mouth breathing if it persists.
-
Dietary Adjustments: Be mindful of your diet and possibly reduce salt intake and spicy foods, which might worsen the sensation of dryness.
-
Jaw Exercises: If jaw discomfort persists, gentle jaw exercises can help relieve tension.
-
Symptom Tracking: Keep a journal noting when the dryness is worse and what you’re eating or drinking at those times. This may help identify patterns.
If symptoms persist despite these adjustments, or if dryness significantly impacts your quality of life, it might be worth discussing further diagnostic options or evaluations with a healthcare professional. Remember that you’re not alone in facing these challenges, and support is available. If you need more information or specific advice, just let me know!

Seeking Advice on Managing Hyperthyroidism Symptoms
I am currently dealing with hyperthyroidism related to Graves' disease. For the past year and a half, I have been taking a daily dose of 5 mg methimazole. However, my endocrinologist informed me that I could discontinue the medication entirely since my TSH levels have returned to normal, and the antibodies linked to Graves' have been undetectable in my most recent tests. It has been nine days since I ceased the medication, but I am experiencing quite prominent symptoms such as a racing heart, tremors in my hands, excessive hunger, and a persistent sense of dizziness and discomfort. I attempted to reach out to my endocrinologist's office for guidance, but I have not received any feedback. What could be causing these symptoms? Is it possible that my thyroid is becoming overly active once more? I would greatly appreciate any suggestions on how to manage these feelings until I can get advice on Monday. Thank you in advance! 39-year-old female.
Seeking Advice on My Burn Injury
Hello everyone. I'm a 21-year-old female from the United States, standing at 5 feet 4 inches tall and weighing 107 pounds. I do not take any medications or drugs and I don’t consume alcohol. While I was baking, I accidentally brushed against the top of the stove, which was heated to about 400 degrees Fahrenheit, for a brief moment of two seconds. I immediately ran cold water over the affected area and applied Neosporin, but that seemed to increase the stinging sensation, so I removed it. Initially, the burn appeared red, but after an hour, it has turned white and continues to hurt. I am uncertain about the severity of the burn (is it a first, second, or third-degree burn?) and what steps I should take next. I appreciate any guidance you could provide. Thank you!
23-Year-Old, 5'11.5" Tall, Weighing 144lbs: Experiencing Shoulder and Neck Pain Post-Fall
I am currently dealing with persistent pain that extends from my back to the right side of my neck, affecting my shoulder and bicep. This discomfort originated after I slipped while skateboarding, resulting in a fall where I landed on my side with my arms stretched out. The pain is always present, intensifying particularly when I am either seated or standing. I find it difficult to tilt my head in either direction; I can manage to turn it a bit to the right, but I struggle to move it even halfway to the left. Maintaining an upright posture is challenging as well. Initially, I rated the pain as a 4 on a scale of 10, but it has escalated to a level 7 over the course of an hour.
Difficulty with Swallowing
Age: 25 Gender: Female Height: 5’2" Weight: 108 lbs Ethnicity: Caucasian Complaint Duration: 1 year Affected Areas: Throat, under jaw, neck Prevailing Medical Conditions: None Current Medications: None --- Hello everyone, I’m reaching out to see if someone might have insights or advice to share. For nearly a year, I have faced challenges when trying to swallow solid foods, which has also led to breathing complications that intensify during mealtimes. Additionally, I experience frequent burping, even when I haven’t consumed anything, such as first thing in the morning. Sudden movements also trigger burps. I have undergone numerous medical evaluations, including two barium swallow tests, an endoscopy, an electrocardiogram, and a CT scan of both my chest and neck. I’ve consulted with two ear, nose, and throat specialists, had ultrasounds on my throat and thyroid, and even visited an allergist to rule out allergies. All these tests returned normal results. I attempted reflux medication, but it was ineffective. I have no issues with stomach pain or bowel movements; my appetite remains, but eating has become quite difficult. At times, it feels as though I have forgotten how to swallow. I perceive a sensation of constriction in my throat, leading to moments where it seems like I’m being choked. Occasionally, I notice discomfort in my neck and jaw muscles. I am hoping someone can provide guidance on how to proceed with this troubling situation. As a brief note, I consider myself to be generally healthy, maintain a vegetarian diet, and seldom get ill. Thank you for any assistance you can offer!
Strange Symptoms Following a Weekend of Drinking
Hello all! I’d like to share a personal experience regarding some unusual feelings I’ve encountered post-drinking, and I’m curious if anyone else can relate. I’m a 21-year-old male, generally quite fit and active. Last Friday night, I indulged in a significant amount of alcohol, mostly taking tequila shots but also having a few dark liquor shots alongside some canned cocktails. The following day, I woke up to a hangover that lingered until about 3 PM before I started to feel better. Later that Saturday, I opted for a lighter drink, consuming around two-thirds of a High Noon, all in the name of celebrating a friend's 22nd birthday with some casual social drinking. However, by Sunday morning, I felt fine initially, but as the day progressed, I began to notice a return of that strange feeling which has persisted throughout the week. Here's a rundown of the symptoms I've experienced: - A sensation of lightheadedness and a foggy feeling, which faded by Tuesday night. - A diminished ability to touch, smell, and taste things. - Persistent fatigue and brain fog (mostly cleared up by Wednesday night). - Occasional muscle twitches, particularly during periods of rest. - An unusually active stomach, marked by frequent growling, gas, and numerous trips to the restroom after eating or drinking. - Increased urination, often within minutes of having water. - Sudden episodes of anxiety or feelings of disconnection. - Occasionally feeling warm (I took my temperature today, and it was normal at 96.3°F) or slightly nauseous, but no vomiting after that initial episode. - Minor coordination issues, like difficulty typing or gripping items, which have since resolved. To aid in my recovery, I’ve been hydrating with plenty of electrolytes, eating light and nutritious foods (such as bananas, yogurt, chicken, and smoothies), and resting as much as I can. Gradually, I’m noticing improvements—the lightheadedness has mostly dissipated and my senses of taste and smell are returning, though my sense of touch and overall energy still feel a bit diminished. After consulting with my doctor, he mentioned that my symptoms could stem from a few potential causes: - Aftereffects of excessive alcohol consumption (especially considering how much I drank). - Fatigue, as I recently finished a demanding stretch of multiple jobs, a weekly golf class, workouts, and an online internship. - The possibility of a viral infection or mild COVID, which I’m currently being tested for. He advised me to continue resting, stay hydrated, take Tylenol or Motrin if necessary, and to check back in on Monday if my condition doesn’t improve. What’s particularly noteworthy to me is that I had a similar experience last year after returning from a trip to Arizona, but that time was much worse. I consumed a mix of Hennessy and D’usse, smoked weed (which is rare for me), and dealt with extreme heat. I ended up vomiting and felt completely off for about a week, even requiring a visit to the ER, where my blood tests came back normal, leading them to suggest dehydration. Given these two incidents, it’s clear that dark liquor is a recurring factor. Despite the differing circumstances, both times I experienced a significant physical and mental crash for several days afterward. Consequently, I've decided to completely eliminate dark liquor from my future drinking habits. Has anyone else gone through a similar experience? Particularly when drinking dark liquor, have you felt out of sorts for days—not just from a hangover, but as if your nervous system or senses are out of whack? How long did it take for you to recover, and what actions aided your recuperation? I’m taking every measure possible to feel better, but I would love to hear from others who might have faced something like this. Any advice, shared experiences, or tips would be greatly appreciated! Thank you! 🙏
