Reactions to Nitrous Oxide During Dental Procedure
Age: 26 Gender: Female Height: 5 feet 4 inches Weight: 150 pounds Ethnicity: European/Thai Current Health Issues: None I underwent the extraction of four wisdom teeth, during which I received nitrous oxide and local anesthesia. At the onset of administering the gas, I struggled to keep my eyes open and experienced an intense reaction, which I now believe might have led to a brief loss of consciousness. The dental team adjusted the nitrous oxide level to approximately 35. Unfortunately, shortly thereafter, I became nauseous and vomited. The gas was then reduced further, possibly to 25. While they were working on my final tooth, I again felt sick and had difficulty breathing. The medical staff had to remind me to breathe, and even with their encouragement, I found it challenging to catch my breath, devolving into a state where my breathing would stop intermittently. It took a couple of minutes before I was able to establish a normal breathing pattern again. Could this indicate an allergy, or are there other factors that might explain this reaction?

It sounds like your experience with nitrous oxide during your dental procedure was quite distressing, and it's understandable that you're seeking clarity on what happened. Your symptoms may indicate a sensitivity or an adverse reaction to the nitrous oxide rather than an allergy.
Explanation
Nitrous oxide, also known as "laughing gas," is commonly used to help patients relax during dental procedures. While many tolerate it well, some individuals can have varying reactions. Your difficulty keeping your eyes open and the nausea you experienced could be due to a few factors:
- Dosing: The level of nitrous oxide is crucial; too high a concentration can lead to side effects like dizziness, nausea, and respiratory difficulties.
- Oxygen Levels: Reduced breathing or feeling lightheaded could occur if there was an inadequate supply of oxygen during the procedure, especially as nitrous oxide can depress respiratory function in some individuals.
- Anxiety and Hyperventilation: Sometimes, anxiety about the procedure can lead to hyperventilation, which might make it challenging to breathe properly.
Next Steps
Here are some prioritized steps to take following this experience:
-
Monitor Your Symptoms: For the next few days, pay attention to how you feel. If you notice any ongoing issues (like extreme fatigue, headaches, or persistent nausea), keep track of them.
-
Hydration and Rest: Drink plenty of fluids and ensure you get adequate rest to support your recovery after the procedure.
-
Follow Up with Your Dentist: Contact your dentist or oral surgeon to discuss what happened. They can provide insights based on your health history, the procedure, and any reactions they observed. Ask about the level of sedation they used and whether this is common for patients.
-
Consider Pre-Treatment Options: In future dental visits, you might discuss alternative sedation methods or adjusting the nitrous oxide dosage to a level that ensures you are comfortable.
-
Communicate About Anxiety: If anxiety played a role, it might be beneficial to discuss strategies for managing this during dental visits, such as deeper breathing techniques or possibly mild sedation alternatives.
Remember, your reactions are important to share with your healthcare providers, as they can help tailor your future dental experiences to ensure your comfort and safety. If you have any severe or concerning symptoms like persistent breathing issues or severe nausea that doesn't improve, please seek immediate medical attention.

Discomfort in the Thumb's Base Joint on the Dorsal Side of the Hand
Hello everyone! I’m turning 26 tomorrow—just a little excited about my birthday. For about a month now, I've been experiencing discomfort at the base of my thumb. The pain is sensitive to touch, and it intensifies when I push down on the middle joint with my other fingers. To clarify, it’s the lower thumb joint that feels sore when I extend my middle joint. I typically pop my middle thumb joints this way, which led me to discover this pain. At my job in a warehouse, lifting heavy items has become quite painful, especially since my work hours were recently reduced from 40 to 20 hours a week, but the discomfort has only increased. I’ve attempted various remedies—ice, heat therapy, wearing a brace, and ensuring adequate rest. I’ve even tried gentle stretching, but without a clear understanding of the issue, I’m unsure which stretches might be beneficial. I want to emphasize that the pain is located on the back side of my hand, not on the palm. This has made researching my symptoms challenging, as most information pertains to conditions like carpal tunnel syndrome or De Quervain's tenosynovitis, which typically cause discomfort on the palm side of the thumb joint. I’m not seeking a precise diagnosis; rather, I’m looking for suggestions that could promote healing and alleviate the pain.
Can My Partially Torn Achilles Tendon Heal on Its Own?
I am experiencing a partial tear of my Achilles tendon near its distal insertion, with the proximal section retracting by about 1.2 cm. As a 34-year-old male who actively participates in soccer, I am concerned about the possibility of recovery without undergoing surgical intervention. My doctor has recommended that I consider orthopedic treatment, but I am hesitant. I would greatly appreciate any insights or encouraging information regarding the chances of natural healing for this type of injury, without resorting to surgery.
Navigating Patella Dislocation: A Trampoline Park Dilemma
Hello everyone, I’m a 21-year-old female, standing at 177 cm and weighing 69 kg. About six months back, I experienced a dislocation of my kneecap while I was dancing. During one of my routines, I landed awkwardly on my right knee, causing my kneecap to shift out of place to the right. Fortunately, my coach was able to reposition it, and I promptly sought medical attention. Thankfully, there were no significant tears, although my knee was quite swollen and a bit damaged. For the subsequent six months, I had to wear a supportive brace and attended physiotherapy sessions a total of twelve times. As of last month, I cautiously resumed dancing. While my knee has improved significantly, it isn’t entirely free from discomfort. Certain movements remain uncomfortable, and I’ve noticed that if I’m feeling under the weather, the pain resurfaces, particularly on the left side of the kneecap. Now, here comes the tricky part. My friends are planning a trip to a trampoline park, and I don’t want to miss out on the fun. However, I’m torn about the potential risk of aggravating my knee. I genuinely wish to join the outing, yet I’m concerned about the possibility of re-injury. I do have a knee support that I wear during my dance sessions. I’m reaching out to see if anyone here has encountered similar situations or could offer advice. Is it safe for me to participate, or would it be wiser to sit this one out? Thanks in advance for your insights!
Understanding Foot Injuries: Bruising or Fracture?
Over a week ago, I suffered an injury to my foot when I accidentally dropped a 35-pound weight on it. Initially, it became swollen and discolored, although the swelling subsided somewhat after a few days. Now, after eight days, the pain remains intense, making it incredibly difficult to walk, particularly when my shoes press against the top of my foot—walking barefoot is also a struggle. After visiting urgent care, I was informed that my X-ray did not reveal any fractures. However, I felt hurried out of the facility without any further evaluation or additional information, except to take ibuprofen, which has had no effect on my discomfort. The bruising persists, albeit not in a very dark shade. I'm left wondering whether a potential fracture could have been missed on the X-ray, or if my soft tissue has sustained such significant damage that it mimics the sensation of a broken bone. Furthermore, I noticed that the top of my foot was somewhat numb the day I sought medical attention, raising additional concerns about the nature of my injury.
Limited Elbow Movement Following Surgical Repair
Two years ago, I experienced a skateboarding mishap where I suffered a fracture that dislodged small fragments from the inner part of my elbow joint. This incident warranted surgical intervention, during which three tiny screws were employed to secure the fragments back in place and a torn ligament was repaired. The operation itself was conducted without complications; however, despite the successful procedure, I have struggled to regain the full functionality of my elbow. Now, more than two years later, this limitation is becoming increasingly frustrating. Throughout this period, I have moderately engaged in stretching exercises aimed at improving my joint’s mobility, but my commitment has been rather lackluster—an oversight I now regret. Recently, I acquired health insurance through my employment, which has prompted me to consider seeking professional evaluation of my elbow to understand possible treatment options. That said, I am somewhat hesitant, fearing that a prescription for physical therapy might only prolong my recovery, leading me to contemplate whether I should continue my home stretching regimen instead. A few details worth mentioning: - My most recent X-ray results indicated no underlying bone issues, according to my physician. - On a daily basis, I can flex my elbow fully, but I can only extend it to about 15 to 20 degrees from completely straight. - Experiencing discomfort when attempting full extension, the sensation is more akin to a stretching discomfort rather than sharp pain. This discomfort intensifies as I reach a hard stop approximately 10 degrees shy of total extension. - Additionally, my elbow joint produces a crackling noise during movement, which my physical therapist attributed to potential scar tissue buildup two years ago. I have a suspicion that the challenges I face may stem from tendon issues or scar tissue formations, but I am not a medical expert! What are your thoughts on this matter?
