It sounds like you're dealing with swelling and possible blood accumulation after biting a hangnail, which can indicate more than just a minor issue. Since you've noticed significant swelling and blood under the skin, it's a good idea to take this seriously.
Explanation: After injuring the skin around your nail, it's possible for bacteria to enter, leading to infection, which can cause swelling and pain. The fluid build-up you see might also indicate a hematoma, which is a localized collection of blood outside blood vessels. While minor injuries often heal on their own, signs of swelling and the changes you've described suggest that your thumb might need further attention to prevent complications.
Next Steps:
- Keep the Area Clean: Gently wash your thumb with soap and water daily to reduce the risk of infection.
- Apply a Bandage: Protect the area with a clean bandage to avoid further irritation and exposure.
- Monitor Symptoms: Watch for increased redness, warmth, pain, or pus, which can signify an infection. If these symptoms worsen, seek medical attention promptly.
- Elevate and Ice: To help reduce swelling, keep your hand elevated when possible, and apply a cold pack (wrapped in a cloth) for 15-20 minutes at a time, a few times a day.
If the swelling does not improve in a few days or if you experience significant pain or other concerning symptoms, it would be wise to seek medical attention to ensure there is no infection or further injury needing treatment. Let me know if you have any more questions!

Understanding Aura Migraines
I experience aura migraines, which come with specific symptoms. For instance, when I notice visual disruptions or aura on the right side of my vision, I typically begin to feel discomfort on the left side of my head initially, and sometimes this extends to pain throughout my entire head. The alternating nature of these symptoms is puzzling to me. Additionally, I wonder if these migraines could also be linked to pain in my teeth. Given that I also deal with sinus issues, how can I determine whether my tooth pain is a result of these factors?
Unexpected Growth in My Mouth Near Uvula
Greetings, everyone. I’ve discovered a strange bump in my mouth, situated right next to my uvula. I first noticed it this morning as I was checking my reflection in the mirror. I don’t engage in smoking or any similar activities, which led me to question whether I should seek medical advice regarding this issue or if it might simply resolve itself. I’m 18 years old and female.
Experiencing Persistent Sound Echoes
Age 32, weight 200 lbs, no medication or substance use. Recently, I've noticed an intriguing phenomenon: after participating in sports or social gatherings, I find that the sounds from those events linger in my mind for hours. For instance, I can recall the squeaking of sneakers on the basketball court, the shouts of my coach, the exchange of common phrases among players, or the clinking of glasses. This occurrence has been part of my life for as long as I can recollect. I distinctly remember returning from a lacrosse match during high school, and even in the stillness of my room, I could still hear my coach's motivational shouts of "let's go!" and "get the ground ball!" echoing for hours after the game. It recently dawned on me that this might not be a typical experience. Could this be considered normal? I came across some information suggesting that such episodes might be linked to dysfunction in the temporal lobe. While I have never undergone an MRI and do not often experience headaches, I'm curious if there are instances of similar experiences that do not stem from temporal lobe issues or if perhaps I should consider seeking medical advice for this matter.
Could These Puncture Wounds Be from a Bat?
I've discovered two small puncture wounds on my skin, spaced roughly half a centimeter apart, but I'm unsure of when this injury occurred. Despite thoroughly searching my home, I couldn't find a bat lurking under the bed or tucked away in any corners. I consulted with my general practitioner, who assessed the bites and suggested they appear more like spider bites. He seemed hesitant to administer a rabies vaccine (ABL vaccine). Given that I reside in Australia, where there are numerous spiders and only four documented cases of rabies from the local strain, I'm left wondering whether it's prudent to advocate for the vaccine. It's perplexing, as I didn’t witness or hear a bat buzzing around my space that might have bitten me while I slept. Furthermore, during the day, I would have certainly noticed a bat resting on my hand. Interestingly, I did pick up a lid from a chicken coop shortly before I noticed the punctures—about 20 minutes prior. I'm uncertain about the next steps to take and would appreciate guidance on how to share a photo of the bite here.
