Could a Tooth Infection Be Behind My Ongoing Headaches?
Hello, I am 35 years old and have been experiencing persistent headaches every day for the last three years. These headaches are primarily located at the top of my forehead. Despite undergoing numerous tests—including a CT scan, MRI, MR venography, lumbar puncture, myelogram, and sinus surgery—none of the results have pointed to a definitive issue, and my imaging findings remain "normal." Several years ago, I underwent a root canal that was fitted with a crown. In February 2020, I started experiencing pain in that tooth, leading me to visit my dentist, who recommended its replacement. However, after the onset of COVID-19, I never returned for the procedure. Since then, I have had intermittent pain, which I managed by rinsing with mouthwash, providing temporary relief. Fast forward to February 2026: I developed an abscess near that same tooth. A visit to the dentist revealed that the infection was severe, and it had begun to damage the bone in my jaw. Consequently, I had the tooth extracted just last week. Now I’m wondering if there might be a connection between my tooth issues and my ongoing headaches. Given that it’s been a week since the extraction, should I expect some relief from my headaches by now?

Tooth infections can indeed contribute to headaches, particularly if the infection has been persistent and has affected surrounding tissues. Given your history of a tooth-related issue and your recent extraction, it’s reasonable to consider whether that could have played a role in your headaches.
Explanation:
Chronic headaches can arise from various sources, including dental problems. In your case, the severe infection in your jaw may have been affecting nerves and surrounding areas, potentially contributing to your ongoing headaches. While you’ve had comprehensive tests ruling out other causes, the tooth infection could have caused referred pain, which means pain felt in one area of your body is actually originating from another area.
Since you had the tooth extracted just a week ago, it's important to remember that your body is still healing. You might experience some residual discomfort or headaches as part of the recovery process, which can sometimes contribute to post-operative headaches.
Next Steps:
-
Monitor Your Symptoms: Keep track of your headache intensity and frequency over the next week. Note any changes in your pain levels, especially after the extraction site starts healing.
-
Pain Management: If your headaches persist, consider using over-the-counter pain relievers like ibuprofen or acetaminophen, following the instructions on the packaging. Ensure you’re also managing any discomfort at the extraction site with your dentist’s recommended post-operative care.
-
Hydration & Rest: Make sure you are drinking plenty of water and getting adequate rest. Dehydration and fatigue can exacerbate headaches.
-
Follow-Up Care: Schedule a follow-up appointment with your dentist to discuss your extraction recovery and any ongoing issues you may be experiencing. They may want to evaluate the healing process or identify if there is any additional treatment needed for your headaches.
If you find that your headaches do not improve in the next couple of weeks or if they become progressively worse, consider seeking further evaluation from a healthcare professional who specializes in headaches for more tailored advice.
Please take care, and I hope you start feeling better soon!

Dealing with Nausea Post-Concussion
A couple of days ago, I experienced a likely concussion after tripping and falling (I’m a 29-year-old male). Following a friend's recommendation who is studying medicine, I have steered clear of screens and anything mentally demanding for the past 48 hours. Fortunately, I haven’t encountered any major complications, which is why I haven’t sought medical attention as of yet. However, ever since the incident, I’ve noticed that I feel a bit nauseous each time I consume food or beverages. Although I haven’t thrown up, the nausea tends to subside after about thirty minutes. I’m reaching out to see if it would be wise to consult a physician? I’m slightly concerned about the expenses, especially if they suggest performing a CT scan or something similar. I appreciate any advice you can provide! P.S. I am not on any medications and do not have any underlying health conditions.
Could This Indicate Cognitive Issues? Time to Consult a Physician?
I am a 39-year-old female weighing 240 pounds, currently taking Mirena IUD, Wellbutrin, and Lexapro. Lately, I've noticed some troubling changes in my reading abilities. It's not just minor letter substitutions; I’m frequently interpreting words entirely incorrectly. The misreadings usually involve words that share the same starting character but diverge significantly in the rest of their composition. This phenomenon began a few weeks back, occurring approximately 3 to 4 times since then. For example, one moment I could read the sentence "she went to the playground," but when I try to recall it later, I mistakenly remember it as "she went to the pharmacy." I have a habit of neglecting to seek medical advice when necessary, and I can’t help but wonder if this could be indicative of a more serious condition that warrants concern.
Understanding Chalazions: Seeking Advice
Hello, I recently noticed a bump forming on one of my eyelids for the past month. Despite applying hot compresses, it has not disappeared, and I’m now experiencing a similar bump on my other eyelid. Could this be a case of chalazions? I'm a contact lens user and have never encountered this issue before. It's been a month, and the original bump is still present, alongside the new one on the opposite eyelid. I am 23 years old, female, standing at 5 feet 3 inches tall and weighing 130 pounds, and of Asian descent. I have no prior medical conditions and am currently not taking any medication.
Seeking Clarity on My Health Issues
I'm reaching out for assistance; any advice would be greatly valued! Approximately a dozen years ago, I unexpectedly started experiencing intense mental fog. I found it difficult to spell, organize my thoughts coherently, and recall simple information. Over a period of months, I began to lose many memories, some of which were quite meaningful to me, like my best friend's birthday. This ongoing memory struggle continues to affect me profoundly and is a source of deep sadness. At that time, I also began to feel an overwhelming heaviness in my legs, almost as if they were weighed down by sandbags or blocks of cement. Although I was diagnosed with restless leg syndrome, that label never truly resonated with me. I didn’t have the urge to move my legs, yet the discomfort would keep me awake at night, and it was also disruptive during the day. Lately, I’ve been grappling with persistent joint and tendon pain accompanied by swelling. Multiple joints are affected daily, with pain shifting from one to another. Additionally, I'm experiencing sensations of pins and needles, hot prickly feelings that induce itching, along with muscle burning from rapid fatigue. A sense of overall tiredness has set in, and just in the last week, I’ve had episodes where my knees buckle, causing me to drop items frequently. Oddly, I’ve also noticed that the arches of my feet seem to have risen significantly in recent months, even though they were already elevated. I exhibit several symptoms consistent with Psoriatic Arthritis (PSA), such as psoriasis, which has led to a referral for testing. However, I’m uncertain whether PSA adequately accounts for some of my earlier symptoms, all of which persist. Is there something that might have been overlooked here? Could this be typical for PSA? To provide some context, I'm a 30-year-old female, overweight but active since I’m a stay-at-home mom, constantly on my feet engaging in various activities like lifting, stretching, and bending. Thank you for your support!
