Could This Have Been a Seizure?
A while back, I had an experience that continues to trouble me. Let me start by clarifying that I am not against vaccinations; I'm simply sharing my personal encounter. After receiving my initial meningitis vaccine, which I believe was administered alongside another one—possibly HPV—I suddenly felt faint. My vision went dark, and I collapsed. Medical staff transported me to another area in the clinic, where they administered smelling salts to revive me. I attributed this incident to not having eaten that day and didn’t experience any further symptoms at that time. However, years later, when I went for my second meningitis vaccine, I informed the clinic personnel about my previous reaction. They dismissed my concerns and assured me that everything would be fine. After a short wait following the vaccination, they deemed me ready to leave. Once I got into the car—thankfully, my guardian was driving—I began to see swirling, kaleidoscopic patterns on the road that wouldn’t leave my sight. Breathing became a struggle, and again, my vision faded to black. I have no memory of what transpired next. When I regained consciousness, I was soaked in sweat and my body was aching. Though it felt like just a few moments had passed, my guardian recounted that I had convulsed and mumbled for approximately 10 to 15 minutes. This incident occurred years ago, but it has left me feeling traumatized, leading to a fear of needles. I find myself wondering whether this could have been a seizure, as I’ve faced skepticism regarding my experience. I'm eager to know if what I experienced was indeed possible. For context, I am 19 years old, assigned female at birth, do not smoke or drink, weigh around 100 pounds, and I am not on any medication.

Your experiences following vaccinations are understandably concerning, and it's important to know that what you went through is significant and deserves careful consideration.
Main Points:
- Your symptoms could indicate a potential seizure, especially given the loss of consciousness and convulsions.
- It's also possible that these reactions were related to vasovagal syncope (a fainting response) due to stress, pain, or other factors.
- It’s crucial to acknowledge your fears and feelings of trauma associated with these experiences.
Explanation:
The episodes you described, particularly the loss of consciousness, confusion, trembling, and mumbled speech following your vaccinations, raise questions about whether they were seizures or possibly a severe fainting episode known as vasovagal syncope. Vasovagal syncope occurs when the body overreacts to certain triggers (like needles), leading to a sudden drop in heart rate and blood pressure, which can cause fainting and sometimes jerking movements.
However, the convulsions you mentioned could align more with seizure activity, which would warrant further investigation. Occasionally, stress, dehydration, or lack of food can contribute to such reactions.
Next Steps:
-
Keep a Detailed Record: Start a symptom diary to document any similar experiences, descriptions of events, triggers, duration, and what happened afterward. This will be helpful if you decide to discuss your experiences further.
-
Consider Medications & Triggers: Reflect on any other stressors, dietary factors, or sleep issues that might have contributed. Ensure you're well-nourished and hydrated before any medical appointments or procedures in the future to help reduce the likelihood of fainting.
-
Educate & Prepare Yourself: Familiarize yourself with what to expect during vaccinations or similar medical procedures. Discuss these preparations with your nurse or doctor to ensure you feel supported.
-
Seek Appropriate Support: If your experience continues to cause you anxiety or affects your daily life, consider seeking support from a mental health professional who can help you cope with the trauma and your fear of needles.
-
Consult a Healthcare Provider: If you continue to have health concerns or similar episodes in the future, consider seeking a healthcare professional who can conduct appropriate evaluations, including possible EEG testing to assess for epilepsy or other conditions.
Recognize that your feelings are valid, and seeking answers or support is important for your well-being. If you have any more questions or need further guidance, feel free to reach out!

Seeking Advice for Anal Bump
As a 19-year-old male standing at 5 feet 5 inches and weighing approximately 130 pounds, I’ve encountered a concerning issue. Recently, I discovered a small bump resembling a pimple located at the entrance of my anus. The exterior feels soft, but upon examination from the inside, it seems to be a small, firm mass, about the size of a corn kernel. Despite my attempts to manipulate it to bring it closer to the surface, there have been no changes apart from the bump turning red due to the pressure applied. I have been distressed by this situation for the last four days and am unsure how long it has actually been present. My instinct is that it could potentially be scar tissue.
Are My Nosebleeds a Sign of a Blood Disorder?
I am a 22-year-old assigned female at birth, standing at 5’3” and weighing 160 lbs. My medical regimen includes fluoxetine, testosterone, and progesterone-based birth control, and I have been diagnosed with Raynaud's syndrome. For as long as I can remember, I have suffered from intense posterior nosebleeds, which can last from half an hour to up to two hours. My routine for managing these episodes includes applying pressure for a quarter of an hour, checking the site for bleeding, and repeating the steps until it ceases. I typically use ice packs and attempt to administer Afrin into the affected nostril. Despite discussing this issue with my healthcare provider, she has shown no concern regarding my symptoms. I undergo laboratory tests biannually for my testosterone therapy, and the results consistently return within normal ranges. Could there be an underlying issue at play? The severity of bleeding in nosebleeds is unprecedented for me; I had regular menstrual cycles before they ceased, and the few significant cuts I’ve experienced have clotted adequately with pressure applied. What could be contributing to the severity of these nosebleeds?
Forgotten Antibiotics: What Are My Options?
Demographics: East Asian Physical Stats: Height - 170 cm; Weight - 64 kg Main Issue: Discussed this with a physician yesterday, but I left my antibiotics at home Location: Hong Kong I’m a 22-year-old individual assigned male at birth (AMAB) experiencing discomfort in my jaw, which may be due to a cavity. I received a prescription for antibiotics yesterday, but unfortunately, I can’t recall the name. The instructions are to take them three times daily, every six hours, over the course of five days. This morning at 7 am, I began my medication, planning to take it with me to work, yet I forgot to pack it. Had I not overlooked this, I would be scheduled for my next doses around 1 pm and 7 pm. The earliest I can return home is 9 pm, but I’m uncertain where I left the medication or if anyone else at home moved it. With lunch fast approaching, it’s impractical for me to go back home or stop by my clinic to retrieve it. What steps should I take next?
Understanding Tonsillitis and Its Symptoms
This morning, I woke up experiencing a painful throat and observed some white patches on one of my tonsils. I had recently met up with a woman who mentioned she had been feeling ill on the day of our encounter, although she eventually started to feel better later that same day. (I know, it wasn't the smartest choice). Initially, I was worried about the possibility of mono or strep throat, so I decided to visit an urgent care center. They conducted a throat swab and took a blood test; fortunately, both results were negative. The physician concluded that I was suffering from bacterial tonsillitis and prescribed antibiotics. I'm curious: what could have resulted in the appearance of white spots on just one of my tonsils? I've dealt with sore throats before, but I've never noticed any white spots before. They resemble tiny tonsil stones.
Unusual Tingling Sensation in My Hands
I've been experiencing an odd tingling sensation and a pins-and-needles feeling in the tips of my fingers every few days. It’s somewhat uncomfortable, though not overwhelmingly painful, and if I sit on my hands for a short while, the sensation typically subsides. After doing some research online, I discovered a lot of concerning information. Should I be worried about this condition or is it likely due to simply using my phone too frequently or overexerting my right hand? I’m a male, weighing 130 pounds and standing at 5'9", born on March 23, 2010.
