Observations of Variations in Pupil Size
A 37-year-old female, standing 5'8" and weighing 168 lbs, reports no habits of smoking, alcohol consumption, or drug use. Recently, she has noticed new, inconsistently sized pupils. This issue first became apparent about a month ago, manifesting every morning but typically subsiding by midday. There have been no changes to her medication regimen. Relevant medical history includes postural orthostatic tachycardia syndrome (POTS), neurocardiogenic syncope, and a persistent right-sided headache that has been present since 2018.

Variations in pupil size can be concerning, especially when they are new and inconsistent. They can be influenced by various factors, including neurological conditions, medication effects, or physiological responses. Given your medical history, such as POTS and persistent headaches, it's essential to approach these changes thoughtfully.
Explanation
Pupil size can vary due to several reasons:
- Physiological Responses: Pupils naturally change size in response to lighting and focusing on objects.
- Neurological Factors: Changes in pupil size may indicate a neurological issue, especially given your history of headaches and syncope.
- Autonomic Nervous System Effects: POTS can affect bodily functions, including pupil response.
The fact that your pupils change size predominantly in the morning and normalize by midday could be related to how your autonomic nervous system is functioning at different times of day.
Next Steps
-
Track Symptoms:
- Keep a journal noting when you notice the changes in pupil size, including any other symptoms (like headache intensity, dizziness, or blurred vision). This can provide valuable insight into patterns.
-
Monitor Related Symptoms:
- Pay attention to associated symptoms such as changes in vision, headaches, or dizziness. If there are any new or worsening symptoms, prioritize further investigation.
-
Hydration & Management of POTS:
- Make sure you stay well-hydrated and manage any symptoms related to POTS. This might include employing strategies recommended for POTS, such as increased salt intake (if advised by a healthcare provider), wearing compression garments, and performing physical conditioning exercises.
-
Avoid Triggers:
- Identify and avoid any specific triggers that may exacerbate your symptoms, including stress or excessive heat.
-
Consider Follow-up:
- If the variations in pupil size persist or if you notice any new or concerning symptoms, consider scheduling an appointment to discuss your symptoms in detail, including your neurological history and headaches.

Unexplained Sharp Pain in the Left Side of My Back
I’m a 38-year-old man, standing at 5 feet 10 inches tall and weighing about 13.5 stones. Although I carry a bit of extra weight, I’m not classified as obese. I maintain an active lifestyle by walking regularly and engaging in various sports. I experience an intermittent, intense shooting pain located on the upper left side of my back, close to my left armpit. To clarify, the discomfort resides in an area that is quite challenging to reach; I cannot easily scratch it with my right arm. To alleviate the itch, I have to stretch significantly from the front and lift my left arm, which hopefully paints a clearer picture. This pain surfaces primarily during physical activities—such as while playing sports, especially after jumping and landing, or when my left arm is extended. Additionally, it occurs when I lie down and take deep breaths. When I inhale deeply, I feel a sharp pinch that results in excruciating, fleeting agony lasting a couple of seconds before subsiding. I suspect this might be related to a nerve being compressed. My main concern is whether there are any methods to relieve the nerve or if this is merely a temporary issue that should resolve on its own, meaning I shouldn't worry excessively. Thank you for any guidance you can provide!
Inquiry Regarding Cauliflower Ear Treatment
Male, 29 years old, weighing 183 lbs at a height of 6 feet with no notable medical conditions and occasionally takes clonazepam. Here's a brief overview of my situation: After a jiu-jitsu session on Wednesday, I experienced a flare-up of my cauliflower ear and sought medical attention. I had the ear drained by a physician on Friday morning, followed by the application of compression magnets. However, by Saturday morning, I noticed some swelling and a refill, prompting me to attempt a self-drain using sterile needles, alcohol wipes, and bacitracin. Although this is a practice some others have done, I realize now it was a misguided choice on my part. My unsteady hand resulted in the formation of another small hematoma, essentially reverting my ear's condition back to what it was on Wednesday. Upon visiting urgent care, the medical staff advised against further drainage due to increased infection risks. They recommended applying antibiotic ointment and continuing with the compression magnets, suggesting that the hematoma would eventually diminish on its own. While I respect medical expertise, I find it hard to believe that this accumulation of blood will simply reabsorb, which contradicts much of what I've read on the issue. I'm finished attempting to drain it myself and have scheduled an appointment with my general practitioner for Monday to get a second opinion and hope for another drainage. I’m seeking advice on whether the urgent care's stance was appropriate. It seems unlikely that draining the blood under sterile conditions carries significant risks. Many individuals who self-treat cauliflower ear often engage in multiple drainage sessions. I’m curious whether I should anticipate my GP turning me down on Monday or if he might consider conducting another aspiration. I’m prepared for the possibility of living with some degree of cauliflower ear, but if drainage isn’t an option, it feels improbable that the hematoma could disappear without intervention. Thank you for your insights. I’ve learned my lesson about self-draining and won’t attempt it again!
Concerned about Possible Head Injury After Hitting Head on Brick Wall
Age: 32, Gender: Female As a smoker, I find myself reluctant to share too many details about last night, but I experienced an unfortunate incident where I struck the back of my head forcefully against a brick wall while under the influence of alcohol. Today, I've been feeling persistent pain in that area, accompanied by a mild headache and tenderness at the impact site. While the discomfort is noticeable, it isn’t overwhelming; I can often forget about it when I’m engaged in other activities. To add to my concern, I noticed some traces of blood on my pillowcase this morning. The incident occurred around 9 PM, and currently, it's just after midnight the next day. I have been taking codeine to help manage the pain, but its effectiveness seems to be fading. I'm grappling with intense anxiety over my condition, which is making it difficult for me to relax enough to sleep.
Understanding Cholestasis During Pregnancy: Is it Critical?
I am a 37-year-old woman currently at 35 weeks along with my first pregnancy. I don’t smoke or drink alcohol, and my current supplements include magnesium, calcium, folic acid, and Unisom for sleep. Recently, I experienced significant itching on the soles of my feet. After some online research, I recalled that itchiness might indicate Cholestasis in pregnancy. Feeling a continuation of the itchiness the next day, I contacted my obstetrician for advice. He presented me with two options: I could either proceed to the hospital today or have my blood drawn at his office on the coming Monday. However, he informed me that test results usually take an entire week to return, and he wouldn’t be able to administer any treatment prior to that timeframe. Considering the logistics, the hospital where he practices—and where I will deliver—is located quite far from my home in New York City, which complicates the situation due to the absence of public transportation. While this won’t pose a problem when I’m in labor, making a trip for a blood test feels unnecessarily burdensome, especially financially since I would need to use Uber for the journey. There’s a medical facility just six blocks away from me, but the doctor specified that if I chose that route, he wouldn’t receive any results from there. I've decided to hold off on making a decision until tomorrow; however, I noticed my urine seemed darker than usual (I’ll ensure I hydrate and recheck, just in case it’s an optical illusion). Now, I’m grappling with the question of whether this condition is truly not urgent. I’ve read that Cholestasis can pose risks to the baby, which understandably causes me distress. The thought of waiting a whole week to address liver issues that may endangered my child is terrifying. Should I consider going to a different hospital where I can get treated sooner, even if that means seeing a new doctor? Is it really acceptable to remain untreated for a week or longer? Additionally, why would it require a full seven days to receive blood test results back from a hospital?
Is It Possible I Restricted Blood Flow to My Brain While Sleeping?
Age: 23, Male I have a peculiar situation to share. This morning, I woke up after just four hours of sleep, having ended up sleeping on my stomach with both arms positioned underneath me. As a result, both arms became numb, which I found unusual since I’ve only experienced this with one arm previously. When I shifted to my side and blood flow returned to normal, I felt a sensation similar to that of a limb waking up—but this time, it was localized on the left side of my head, in the parietal region. Since that moment, I haven’t noticed any significant issues, apart from a persistent headache that has lingered throughout the day. I recognize that I might be overreacting, especially considering it’s about my head, but I feel the need to exercise caution. Is there a possibility that I inadvertently restricted blood flow to my brain while sleeping in that position?
