Understanding a Cut on My Lip After a Root Canal: What Could It Be?
I've posted some details about this issue on a dental Reddit forum since image sharing isn't an option here. I'm a 31-year-old woman who recently visited the dentist for an urgent issue. After a root canal procedure, I've noticed a peculiar bump or opening on my lip that resembles a cut. I'm unsure if it resulted from biting down on the X-ray apparatus or during the tooth filling process itself. The appearance of this injury concerns me, and I want to learn more about what it could be and how to treat it. This sore area looks quite unpleasant, and I only became aware of it after I returned home and the anesthetic wore off. I'm uncertain if the dentist noticed it while I was unable to respond during the procedure. Is it common for such injuries to occur following dental work? Any tips or recommendations for treating this would be greatly appreciated. Thank you!

It sounds like you're experiencing some discomfort from a lip injury that may have occurred during your recent dental procedure. It's not uncommon for soft tissue injuries like cuts or bites to happen in dental settings, especially when equipment is used in the mouth. Let’s break this down to better understand your situation and how you can manage it.
Main Points
- The bump or cut on your lip may result from the dental procedure.
- It's relatively common for minor injuries to occur during dental work.
- Proper self-care can aid in healing.
Understanding the Injury
After dental procedures, especially those involving the use of tools or equipment close to the mouth, it's possible to sustain minor injuries, such as cuts or irritation on the lips. This can happen if you bit down on instruments or if the dental tools accidentally caused trauma while you were unable to feel or respond due to the anesthetic.
Next Steps for Care
-
Keep it Clean: Gently clean the area with mild soap and water to prevent infection. Avoid using alcohol-based mouthwashes, as they can irritate the sore.
-
Avoid Irritants: Refrain from abrasive foods (like chips or spicy foods) and avoid tobacco products, as they can worsen the irritation.
-
Pain Management: If you're experiencing discomfort, consider over-the-counter pain relievers such as ibuprofen or acetaminophen. Always follow the instructions on the package for dosage.
-
Monitor Symptoms: Keep an eye on the injury. If it doesn't improve within a week, or if it becomes more painful, swollen, or shows any signs of infection (such as pus or increased redness), it's important to seek professional evaluation.
-
Hydration and Diet: Ensure you're staying hydrated and eating soft foods to minimize irritation to your lip while it heals.
Reassurance
It’s good that you’re attentive to changes in your body, and most minor injuries like this resolve on their own with proper care. If you have any new symptoms or increased concerns, don't hesitate to reach out for further assistance. Healing takes time, but being proactive can make a difference. If you need more clarification or have further questions, feel free to ask!

Noticing a Pulse in My Suprasternal Notch
Hey everyone, I’m 20 years old, standing at 165 cm and weighing 60 kg. I don’t take any medications, I’m a non-smoker and I drink alcohol only on rare occasions. I have no significant medical history to report. I want to share something that’s been a part of my life since childhood, likely starting when I was around ten or younger. I have a distinct pulse visible in the area of my suprasternal notch. This became particularly noticeable to me during my swimming days. After practice, I would often catch a glimpse of it in the mirror while drying myself off, and it’s remained a consistent observation throughout the years. Remarkably, it has never caused me any distress. Now, as I approach 21, that pulse is still apparent, especially when I focus on it closely. I’ve noticed that the skin in that region is quite thin, but aside from its visibility, I haven’t experienced any adverse effects—no discomfort, swelling, or issues with my breathing. The only real concern I grapple with is health-related anxiety, which occasionally heightens my awareness of such things. At times, I completely forget about this pulse, while other times, I may catch sight of it in the mirror and start to question whether it's a normal occurrence or a sign of something more serious. So, I'm reaching out to see if anyone else has experienced a similar phenomenon. Is this visible pulse in the suprasternal notch a typical condition? Should I be concerned about it? Thanks in advance for your insights!
Concerns About Petechiae on My 3-Month-Old
This evening, I discovered that my 3-month-old son, who was born prematurely at 34 weeks and experienced intrauterine growth restriction (IUGR), had petechiae visible under his chin and along one side of his jaw while he was feeding. I reached out to his pediatrician immediately, but it was already past 9 PM. I have been monitoring his temperature diligently, and he hasn't developed a fever. Earlier today, he had been fussier than usual. To provide some context, I had undergone surgery a week ago, which meant he was on formula alone for approximately 36 hours. His usual feeding routine consists of half 24 calorie Neosure and half breast milk. During the formula-only period, he was especially cranky in the evenings and consumed only 2 to 2.5 ounces instead of his normal intake of 3.5 ounces. Once I reintroduced breast milk, his fussiness improved, but around day five following my surgery, he became gassy and returned to consuming only 2.5 ounces. I attributed this to a recent switch in his nipple size from preemie to level 1, so I changed it back to a transitional nipple. Since then, he has consistently consumed between 2.75 and the full 3.5 ounces over the last 24 hours. However, during his 6 PM feed, he showed significant fussiness and only drank 2.5 ounces, prompting me to administer Mylicon drops. Just before his 9 PM feed, he seemed extremely hungry and became quite agitated while awaiting his bottle to warm. He was making a high-pitched scream, turning purple, and seemed to be losing his voice while thrashing in my arms. Once fed, he eagerly finished his usual 3.5-ounce bottle and promptly fell asleep. Later, he completed his nighttime feeding of 3.5 ounces with minimal intermittent fussing due to gas. In my research about petechiae, I learned that it can be associated with meningitis; however, he displays no fever, stiffness in the neck, or bulging fontanel. He has been fussy intermittently and has not consistently completed his bottles. It’s now 2 AM, and upon checking again with a flashlight, I observed a few singular dots near his eyes, on his nose, and around his chest and neck area. It is unclear whether I simply missed these earlier or if this condition is worsening. I also wonder if the petechiae could have resulted from him straining during his distressing episodes of crying. I am uncertain whether I should wait until morning for further guidance or take action now, especially since the last two feeds he completed fully, despite previous eating inconsistencies.
Using Clindamycin 600mg Twice Daily for Acne Treatment
At 23 years old and weighing 200 pounds, I've been grappling with serious acne primarily around my neck, with occasional flare-ups on my cheeks. Initially, my condition started to improve thanks to a prescription for Aknemycin Plus, which combines erythromycin and tretinoin. However, my doctor later reverted back to an earlier treatment, Aklief (trifarotene), which unfortunately proved ineffective, leading me to discontinue its use. Recently, my doctor expressed significant concern about my acne; I had mentioned that I felt the prior medication was beneficial. He suggested trying Accutane, which requires monthly blood tests as part of the regimen. I decided against that option since my breakouts aren't overly severe. Subsequently, he reinstated my prescription for Aknemycin Plus and added an ointment along with Clindamycin tablets at a rather high dosage. I must admit I feel a bit anxious about this approach, especially since I discovered that Clindamycin is not typically employed for acne treatment, particularly at such elevated doses. If anyone has insights or experiences concerning this medication, I would greatly appreciate your input.
Concerns about Fever and Crossed Eyes in My 4.5-Year-Old Daughter
Hello, I’m reaching out because I’m worried about my daughter’s condition. Approximately a month ago, she suffered from atypical pneumonia, which was treated with a series of antibiotics, including clarithromycin, due to her low oxygen saturation (90-92%). Thankfully, her condition improved, and she required temporary oxygen support. Now, a month later, she has developed a fever, peaking at 38.7°C about seven hours after taking ibuprofen. Over the course of two and a half days, she experienced three episodes of vomiting, and the doctor diagnosed her with viral enterocolitis. Alongside this, she has complained about mild pain in her head, arms, and legs, though it subsided after administering antipyretics. The physician attributed these pains to her fever, noting there was no stiffness present. However, yesterday evening, she seemed dizzy and was unsettled when I carried her down the stairs. Today, she is exhibiting a slight strabismus (crossed eyes) that wasn’t there before. It appears she’s having difficulty tracking my finger, and her vision seems unclear as she struggles to count them accurately. The healthcare professionals have reassured me, expressing that they are not overly concerned about the strabismus, attributing it to the fever. This is troubling for me, especially considering her previous health issues, and I cannot shake the worry about meningitis despite her vaccinations. I’m contemplating transferring her from this local hospital to a pediatric specialty hospital for a neurological assessment. Her fever has decreased with ibuprofen, and they are currently conducting blood tests. I would really appreciate any insights or advice regarding my daughter’s situation.
