Persistent Submandibular Lymph Node for Over Two Years
A 22-year-old female reports the presence of a solitary bump located in the submandibular region for more than two years. The bump is movable and has a slightly flattened shape rather than being perfectly round. When lightly touched, it shifts either upwards or sideways. Although it isn't discernible externally, there is an absence of this bump on the contralateral side. The patient has a history of TMJ dysfunction and atypical facial pain on the affected side, raising concerns about the possibility of adenoid cystic carcinoma affecting the salivary glands. Notably, the bump has not undergone any changes in size and is not associated with pain. An examination of the floor of the mouth reveals no abnormalities. The patient is also considering scheduling an ultrasound next week to further investigate this issue. Recently, a head MRI was performed and yielded normal results, as did a recent Cone-Beam Computed Tomography (CBCT) scan.

It’s understandable to be concerned about a persistent lymph node, especially given your specific symptoms and medical history. The bump you describe in the submandibular region, which has been stable and is associated with TMJ dysfunction and facial pain, likely indicates a benign condition. Nonetheless, it’s crucial to carefully monitor such issues, particularly since you are considering further imaging.
Explanation:
Lymph Nodes and Benign Conditions: The lump you’re feeling could be a reactive lymph node, often due to minor infections or inflammation, particularly in the area of the jaw and mouth. The fact that it has been stable in size, is movable, and is not tender typically suggests it is not immediately concerning.
Imaging Results: The normal MRI and CBCT results are reassuring and suggest that there are no alarming masses or significant problems in the tissues examined. However, your concerns about adenoid cystic carcinoma, though understandable, tend to arise in cases of painful, rapidly changing masses, or other distinct symptoms.
Next Steps:
-
Follow Through with the Ultrasound: Schedule and have the ultrasound done as planned. This imaging can provide more detailed information about the characteristics of the lymph node (like its exact structure and whether there are solid components).
-
Monitor Symptoms: Keep a close watch on any changes in the lump (size, firmness, tenderness) and your facial pain. If you notice any new symptoms, such as difficulty swallowing, changes in saliva, or swelling, note them down.
-
Consult with Your Healthcare Provider: Ensure that you discuss the results of the ultrasound with your healthcare provider, along with your ongoing symptoms, to determine if any further investigation or reassurance is needed.
-
Consider TMJ Management: Since you have TMJ dysfunction, addressing this with appropriate therapies or exercises could help alleviate your facial pain, which may lessen your overall discomfort.
If you have any further questions or need clarification about any of these steps, please feel free to ask! Your health and peace of mind are important.

Concerns About Colon Cancer
An Overview and My Personal Experience As a 31-year-old male, I have remained a non-smoker and non-drinker, with no known cases of colon cancer in my family. Standing at 5’8” and weighing about 170 pounds, I find myself contemplating my health with unease as I navigate this journey. My first brush with rotavirus occurred in October 2024, followed by another bout just a few months later in February 2025. In fact, I have dealt with this virus approximately four times throughout my life, including a recent episode in April 2023, which taught me a valuable lesson about the perils of playgrounds when children are involved. I am passionate about running and currently gearing up for a marathon this October. Generally, I feel fit and energized, although during my last two training cycles over the past year, I encountered challenges related to fuel intake and gastrointestinal discomfort, commonly referred to as "runner’s stomach." Lately, I've noticed a change in my bowel habits, particularly experiencing thinner stools. Referring to the Bristol stool chart, it's been some time since I've seen a type 3 stool (the ideal "cracked sausage")—the last three months have predominantly featured either smooth formations or fragmented pieces. This prompted me to consult my doctor, and I’ve been in touch with the nurse practitioner from the office. Blood tests returned normal, including my hemoglobin levels, and a breath test for H. Pylori also yielded negative results. A fecal test for blood was similarly clear. Currently, I am on a gluten-free diet for the last month, and we’re in the process of exploring an elimination diet. What weighs heavily on my mind is the possibility of colon cancer overlooked while focusing on other conditions. I suggested a colonoscopy as a definitive step, and while it has been considered, the team is prioritizing other potential explanations for my symptoms right now. My anxiety is considerable, particularly because I am a husband and father to two children. I am reaching out for any advice on how to proceed from here, particularly about what else my symptoms might indicate. We briefly discussed the possibility of irritable bowel syndrome (IBS), and I’ve been increasing my fiber intake. Generally, I strive to maintain a healthy diet, although I did experiment with magnesium citrate recently under the NP’s guidance; however, it seemed to irritate my stomach. Any insights would be greatly appreciated.
Feeling Heavy-Headed After a Motorcycle Incident
I am a 17-year-old male, weighing 70kg and standing at 163cm tall. Just two days ago, I was involved in a motorcycle accident. Although it wasn’t severe, I ended up fracturing one tooth and cracking another, leading to swollen lips and some bruising on the right side of my face. Thankfully, I did not suffer a concussion or any direct impact to my head, as my helmet protected me during the fall. I received medical care, during which the doctors checked for signs of concussion and asked if I experienced any nausea, but I did not. However, upon waking up the following morning, I began to feel an unusual heaviness in my head. This sensation has been troubling me, especially because I've been anxious about the possibility of a blood clot in my brain after overthinking the situation. Right now, I am feeling quite frightened. Can anyone provide insights on what might be causing this and what steps I should take next?
Concerns About Ear Infection and Associated Symptoms
Throughout my life, I have experienced persistent discomfort in my ears. For the past three years, I've been dealing with significant itching, soreness, an unpleasant odor, and discharge. Finally, in late November, I sought medical help for this ongoing issue. The doctor performed a scrape of my ear and prescribed two rounds of antibiotic ear spray. Unfortunately, these treatments did not resolve the infection, leading to a prescription for Amoxicillin, which also failed to clear it. Meanwhile, I developed a chronic cough that worsened over a two-week span. Afterward, I returned to the doctor to address both the continuing ear infection and the cough. I was given Clarithromycin, and a swab was taken from my ear in hopes that this antibiotic would tackle both ailments. Just three days later, I received a call from the ENT clinic followed by another call from my GP, who advised that I start taking Metronidazole in conjunction with finishing my Clarithromycin course. Upon reviewing my NHS app, I found the swab results indicating 'abnormal: Anaerobes ISOLATED.' This discovery has left me feeling concerned, and I've been researching the implications. Should I be worried about severe complications like necrosis, meningitis, or brain abscesses? Additionally, does the infection relate to the cough I have, which has certainly lessened, although it remains bothersome as I enter week four? I’ve also been struggling with overwhelming fatigue to the extent that falling asleep at work has become a frequent occurrence. Furthermore, I've been experiencing excruciating pain in my toes, for which arthritis has been ruled out. My thyroid tests showed a borderline TSH level, yet no further examination was suggested. I'm curious if all these symptoms could be interconnected. Currently, I’m on day three of Metronidazole treatment, but my ear condition shows no sign of improvement. I'm seeking any insights, advice, or suggestions on how to manage this situation.
Concerns Regarding Autoimmune Conditions
Age: 22 Gender: Female Greetings everyone, I understand the typical response is to suggest seeing a healthcare professional, but I'm hoping to gauge whether my worries are unwarranted and if a visit to the doctor is truly necessary. Here's a brief overview of my situation in chronological order: - In July of last year, I experienced intense abdominal pain accompanied by blood in my stool, leading to a diagnosis of Crohn's disease. - To manage this, I was prescribed prednisone to alleviate the symptoms. - Subsequently, I began using Humira in October of the same year. - In February, I developed hidradenitis suppurativa and experienced some minor red, itchy dry patches on my palms and right leg. Due to ongoing issues, I switched to Entyvio in February 2025. - After this transition, I started to feel occasional mild pain in my right heel. - Furthermore, I experienced some discomfort in my right shoulder intermittently, likely from a previous softball injury. - A new concern arose with sharp pain on the right side of my chest, specifically where my sternum meets my ribs. I suspected it might stem from Pilates, but I had practiced with extreme caution, questioning why it was so severe and debilitating. - Over the last few weeks, I also noticed pain in my hip area, particularly in my upper glute and lower back, including joint pain that I suspect could be related to sciatica. This discomfort worsens with sitting or standing but improves slightly when going upstairs or in a squatting position. The pain has become so intense that I’ve had to use a walker, which feels overwhelming at my young age. In my research, I’ve learned that my Crohn's condition may increase my risk of ankylosing spondylitis. Additionally, the red patches on my skin could indicate psoriatic arthritis. I'm seeking opinions on whether my symptoms might be indicative of a more serious health issue beyond just common aches and pains.
An Array of Cysts: My Ongoing Struggle
I have a medical history that includes Hashimoto’s thyroiditis, polycystic ovary syndrome (PCOS), irritable bowel syndrome (IBS), frequent migraines, high blood pressure, gastroesophageal reflux disease (GERD), major depressive disorder (MDD), complex post-traumatic stress disorder (C-PTSD), generalized anxiety disorder (GAD), and obesity. Medications I take include Synthroid, Protonix, Bentyl, Norvasc, Emgality, Maxalt, Cholestyramine, Prozac, Remeron, Mini Press, Belsomra, and vitamin D. In recent years, particularly over the past five, I've encountered a plethora of different cysts. My journey began with a pilonidal abscess, a condition I still find challenging to manage. Following that, I developed abscesses beneath my breast, in my groin area, and on my elbow, which my doctors attributed to sebaceous cysts. Additionally, I've experienced three ganglion cysts: two located on my hands and one on my foot. Furthermore, I've had Bartholins cysts twice and have cervical nabothian cysts that have begun to bleed. There’s also a cyst on my thyroid and another on my ovary that is being monitored closely. Lastly, I’ve dealt with a Baker's cyst. I also suffer from cystic acne, which is likely linked to my PCOS. My skincare routine involves daily showers, exfoliating three times per week, wearing mostly cotton fabrics, and using Dove products due to my sensitivities to other soaps. I can't help but wonder, am I simply extremely unfortunate? While I understand that obesity can contribute to some types of sebaceous cysts, I'm actively seeking assistance to manage my weight. Is there a potential connection between the different types of cysts I am experiencing?
