Understanding Large Arachnoid Cysts
Greetings, I’m a 29-year-old male, standing at 192 cm tall and weighing 108 kg. It turns out I have a cyst measuring 35 mm by 82 mm located at the rear of my head. My journey began when I started experiencing dizziness and occasional balance issues, prompting me to seek medical advice where the cyst was discovered. Notably, I find that bending my head forward triggers these dizzy spells, and if I maintain that position—such as when I inadvertently nod off on public transport—I become overwhelmingly disoriented, struggle to keep my eyes focused, and feel nauseous. My physician has informed me that these symptoms are unlikely to resolve and has recommended annual MRI scans to monitor the situation. If any increase in size is noted, surgical intervention may be required. Additionally, the doctor advised me to avoid any head impacts due to the potential risk of rupture. I would appreciate your insights regarding this cyst and whether it might be prudent for me to seek a second opinion from another medical professional. Thank you in advance!

Thank you for sharing your situation. It's understandable to feel concerned about your diagnosis and the symptoms you're experiencing. Arachnoid cysts can vary in their impact on individuals, so it's important to ensure you have a full understanding of your condition and the best management strategies.
Key Points:
- You have a large arachnoid cyst that might be contributing to your dizzy spells and balance issues.
- Your physician recommends annual monitoring through MRI scans and has advised against head impacts.
- Seeking a second opinion can provide additional insights and peace of mind regarding your treatment plan.
Explanation:
Arachnoid cysts are fluid-filled sacs that can form on the brain or spinal cord. They are often incidentally discovered during imaging studies, as many people do not experience symptoms. However, larger cysts, like yours, can cause symptoms such as dizziness, balance problems, and nausea—especially if they are pressing on nearby structures or if changes in posture affect them.
Given that your symptoms are connected to neck positioning, it indicates that the cyst might impact the surrounding nerves or areas of the brain that control balance and spatial orientation. Monitoring through MRI is crucial because any increase in the size of the cyst can lead to worsening symptoms and may necessitate surgical intervention.
Next Steps:
-
Monitor Symptoms:
- Keep a detailed diary of your symptoms, noting when they occur, their intensity, and any activities that trigger them. This can be helpful for any future consultations.
-
Consider Second Opinion:
- If you feel uncertain about your current management plan or need clarification about your symptoms and potential intervention, seeking a second opinion from a specialist (such as a neurologist or neurosurgeon) is prudent. They can review your imaging and provide additional recommendations tailored to your situation.
-
Avoid Triggers:
- Be cautious with movements that trigger your symptoms, such as bending forward. If drowsiness occurs on public transport, try to maintain a position that doesn’t exacerbate your symptoms. Consider consistent posture reminders.
-
Emergency Awareness:
- Be aware of signs that require immediate medical attention, such as severe headaches, sudden changes in vision, confusion, or any new neurological symptoms.
Your health journey is important, and you're doing the right thing by staying informed and proactive. If you need further advice or specific questions about your condition, feel free to ask!

Identifying a Leg Blister: Burn or Bite?
At 21 years old, standing at 4'11 and weighing 106 pounds, I have been prescribed medications including Concerta, Lexapro, and the minipill, in addition to using a condom for sleep purposes. This morning, I discovered a blister on my leg. I had been using a heating pad while I slept, although I've never had it set to such high temperatures, as it has an automatic shut-off feature. Nevertheless, I'm aware that circumstances can vary. To address the issue, an NP (Nurse Practitioner) treated the area with iodine and drained the blister. I've also started a course of antibiotics, both topical and oral. So far, there's been no indication of blue or purple discoloration. I'm contemplating whether I should seek additional medical advice or stick to my current plan. They provided me with a note excusing me from work tomorrow, but I'm indecisive about whether to stay home and keep an eye on my leg or to go in. I wish I had more clarity about the nature of the blister, as I'm hesitant to let it worsen without proper guidance. Any advice on the best steps to take next would be appreciated!
Concerns Over Babinski Reflex in a Toddler
I have a daughter who is 2 years and 5 months old, standing at 3 feet tall and weighing 33 pounds. She has been diagnosed with reactive airway disease and is on a daily regimen of Zyrtec and albuterol. Notably, she exhibits a positive Babinski reflex in both feet, along with a positive plantar grasp. However, the Babinski response is only mildly positive, primarily evident through her toes lifting without significant fanning. Fortunately, she hasn't shown any other developmental delays. Since she turned 1, she has been using a spoon quite well, constructs sentences of five words, and jumps off the ground using both feet. Should I express concern about her Babinski reflex or allow more time for her development?
Inquiry About Surgical Procedure Complications
This is a temporary account for posting, and I'm not certain if I'm in the right place to ask, but I hope someone can help me. Please excuse any mistakes in my writing; I struggled academically in the past, which led to my early departure from school, so I appreciate your understanding. I'm a 19-year-old female. When I was around 16 or 17, I underwent a breast reduction procedure. My surgeon was extremely kind, providing thorough explanations of the process and addressing any questions I had beforehand. However, that’s not the source of my current worries. Following the surgery, which extended beyond the timeframe my mother had been informed about—by a couple of hours—the hospital didn’t clarify the reasons for the delay. After awakening from anesthesia, I changed and was discharged to go home. However, upon returning, I experienced an urgent need to use the restroom. My mother drove us back because I wasn’t allowed to utilize the hospital facilities. Upon using the bathroom at home, I discovered I was bleeding significantly, and my thighs felt unusually sore and appeared red. I confided in one of my older sisters, and she found it concerning. When I approached my mother for further information, she mentioned that the medical team had utilized some device to control the bleeding. I have no idea where she obtained that information, but that’s what I was told. Now, several years later, I still find this troubling. I attempted to research online to see if others who had experienced breast reduction surgery encountered similar issues but didn’t find anything relevant. It could be that I wasn’t searching effectively, but what’s important to me is this: **Is there a medical instrument employed internally to manage bleeding during a breast reduction operation?**
Navigating Four Years of Persistent Throat Issues and Unpleasant Odor
For the past four years, I have been grappling with ongoing health concerns that seem to have no resolution in sight. My difficulties mostly revolve around my throat, nasal passages, and sinuses. Here’s a summary of what I’ve been experiencing: - A foul odor emanating from my throat that resembles either the scent of an elderly person or even something decomposed. - Frequent episodes of soreness in my throat, occurring approximately once a week, albeit mild in nature. - A persistent blockage in one of my nostrils, while the other remains perpetually open. - An almost unrelenting sensation of something dripping down the back of my throat. - A daily feeling that something is lodged in the area where my throat and nose connect, situated just above my vocal cords. - For almost the entire duration of these four years, I’ve had inflamed tonsils that seemed to touch my vocal cords. - I underwent a tonsillectomy a year ago, hoping it would alleviate my problems, but unfortunately, the discomfort persists, though the tonsils are no longer present in my throat. A bit about myself: I am a 30-year-old male, otherwise healthy, maintaining good dental care practices. I brush my teeth up to three times daily, often even four, and ensure I clean my tongue and use dental floss regularly. I am reaching out in hopes of finding some guidance. I’m at my wit’s end and willing to explore any options that might help resolve this situation.
Strategies to Prevent Picking at Surgical Scars
Recently, I (female, 23 years old) underwent surgery to have my gallbladder removed, and it’s been about a week since the procedure. Initially, everything seemed fine until I became aware of the scabs forming on my abdomen. I have four scars and, given my history of self-harm, I find myself unable to resist picking at them. Just today, I accidentally tore open the largest scab, which I presume is from the site where my gallbladder was extracted. Thankfully, there was no bleeding, but I am quite worried about the possibility of developing an infection! In an effort to protect myself, I’ve placed large band-aids over the affected areas; however, the effects are temporary, as I frequently find myself drawn to them again and inevitably start picking. I’ve attempted to keep myself occupied by watching television, playing video games, and scrolling through my phone, but nothing seems to keep my mind off it. I even asked my family for help, but their support has its limits. I'm reaching out to see if anyone has effective strategies to help me cease this habit beyond simply giving myself verbal encouragement. Also, how serious is the risk of infection in this situation? With several pets around, including two dogs and a few cats, I feel like that could complicate things even further.
