Sudden Facial Swelling and Limited Jaw Mobility – Exploring the Cause
I typically have a regular dental cleaning once every six months, and after my latest appointment last night, I went to bed feeling completely fine. However, upon waking up this morning, I discovered my cheek was noticeably swollen, and I struggled to open my mouth beyond half an inch. While I experienced no tooth pain, I did notice some sensitivity in my back molars when I clenched my jaw, which led me to suspect a potential dental issue. After visiting my dentist today, I learned that they don’t believe it’s an abscess but rather an isolated condition affecting my cheek. The swelling extends from the area just beneath my eye down to my jaw. To address this, my dentist prescribed antibiotics and suggested I undergo an X-ray prior to my next appointment next week to eliminate any dental complications. I’m not experiencing ear pain, my throat is fine, and there’s no inflammation in my glands. Although my back molars on the swollen side remain sensitive when I bite down, the discomfort is minimal. I haven’t checked my temperature but don’t feel feverish. I have no ongoing health issues, and I’m not currently taking any medications or have any known allergies. I’m somewhat anxious about the sudden onset of this swelling and the possibility of it worsening overnight. If my condition deteriorates by morning, I would appreciate any thoughts on what other potential issues could be at play.

Sudden facial swelling accompanied by limited jaw mobility can be concerning, but it’s good that you’ve already consulted with your dentist and started antibiotics. The swelling you’re experiencing could be due to several factors, such as an infection, inflammation, or even an allergic reaction.
Since your dentist doesn't believe it’s an abscess but has recommended further evaluation, it’s important to continue monitoring your symptoms.
Here’s a breakdown of your situation and what you can do next:
1. Monitor Your Symptoms:
- Swelling: Keep an eye on whether the swelling increases or decreases.
- Jaw Mobility: Note any changes in how much you can move your jaw.
- Sensitivity: Continue to assess the sensitivity in your back molars—if it worsens, this could be significant.
2. Immediate Care:
- Cold Compress: Apply a cold compress to the swollen area for 15-20 minutes several times a day to help reduce swelling and discomfort.
- Over-the-Counter Pain Relief: If you experience discomfort, consider taking over-the-counter pain relief such as ibuprofen (unless you have contraindications).
3. Hydration and Diet:
- Stay well-hydrated and consider soft foods that require less chewing to avoid aggravating your jaw.
4. Signs of Deterioration:
If by morning you notice any of the following symptoms, it’s important to seek immediate attention:
- Increased swelling or extreme discomfort
- High fever (above 101°F)
- Pus or drainage from the swollen area
- Difficulty breathing or swallowing
Next Steps:
Continue taking the prescribed antibiotics as directed, and attend the follow-up appointment for the X-ray to rule out any dental complications. Keeping an eye on your symptoms and addressing them promptly will help ensure your situation does not worsen. It’s natural to feel anxious, but you are taking appropriate steps towards management.

Concerns Over Decreased Platelet Counts with SSRIs
I am a 20-year-old female, standing 5 feet tall, and I was diagnosed with Obsessive-Compulsive Disorder (OCD) in 2023. In January 2024, I started treatment with fluoxetine at a dosage of 20 mg, which was quickly raised to 40 mg. Following this increase, I've experienced some unusual skin symptoms, specifically tiny red dots beneath the surface that are subtle yet peculiar. Unlike the petechiae I have encountered previously, these spots seem to originate from the skin pores themselves, appearing more inflamed and noticeable than usual. I have been undergoing regular blood tests, all of which have revealed a consistently low platelet count along with a high mean platelet volume (MPV). My preliminary research suggests that this condition could point toward an increased turnover of platelets. Dealing with both OCD and health-related anxiety, I often find myself fixating on the possibility of having a serious illness such as leukemia. Although my physician has not expressed major concern regarding this issue, my platelet levels have seen a decline since September of the previous year, dropping from 146 µg/L to 131 µg/L just last week. Should I be worried about this situation? Could my medication be contributing to these changes?
Questions Regarding Colonoscopy Results
A few months prior, I underwent a colonoscopy as part of routine screening. Thankfully, the procedure revealed no polyps, and I experienced no complications. While reviewing my results, I noted that the procedure had successfully reached the cecum and that the bowel preparation was rated as excellent. What struck me as peculiar was the phrasing in the report stating, "the colon (entire examined portion) appeared normal." This specific wording was also referenced in other parts of the document. I can't help but wonder why this distinction was made. Is there a segment of the colon that isn't routinely inspected during a standard colonoscopy? What is the purpose of including such qualifying language in the report?
Concerns About a Gum Issue
As a 31-year-old female, I've noticed a small white spot located on the lower region of my gum line. It resembles a canker sore in texture, yet it has a distinct white center, raising my concern that it might be a cyst.
Noticed a Lump in My Thigh (Unseen)
I've discovered a lump located beneath the skin of my upper thigh. Interestingly, it isn’t visible; I can only notice it through touch. The lump isn’t particularly large—its size is comparable to, or perhaps a bit smaller than, the tip of my pinky. It feels tender when I apply pressure, but it doesn't cause any real pain. Should this be something I need to address promptly? I am a 51-year-old woman, standing at 5’2" and weighing 115 lbs. I do have fibromuscular dysplasia; however, I manage it with just baby aspirin.
Unusual Sensations in My Biceps
Male, 18 years old I came across something peculiar recently. Whenever I touch the area underneath my armpit, near my biceps, it feels as though there are small hard lumps—similar to marbles—beneath the skin. This sensation isn’t visible externally; it’s just something I can feel. I'm reaching out to see if this could be a sign of something serious? Any insights would be appreciated. Thank you!
