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.
By keeping track of your observations and managing your current conditions, you can help ensure that any underlying issues are properly addressed. Let me know if you need more information or assistance!

Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
Concerns About My Toes
Age: 30, Female Currently, I am on the lookout for a reputable podiatrist in my vicinity. However, I've encountered a perplexing issue with my foot. Just last night, I noticed a growth on the side of my toe, something entirely new to me. I maintain a nutritious diet and have a demanding job that requires me to be on my feet quite often. My footwear includes brands such as Brooks Ghost Runners, Hoka Bondi 9’s, and Nike Motiva’s, and I don’t opt for restrictive socks. I also apply Vick’s Vaporub to my feet, a practice handed down from my family, and stick with simple, non-fragrant lotions like Vanicream and CeraVe SA Cream for my skin. In addition, I am curious about the my big toenail's change in color. What might be the underlying reasons for this? Also, I have these persistent dark spots on my toes that I've struggled with since my days on the runway. Despite my efforts, nothing has succeeded in lightening or diminishing their appearance. I'm just looking to determine if there might have been a factor from the past that could have contributed to these issues. I’m not sure what else to include, but I’m open to answering any questions you might have. Thank you for your attention! Best wishes from a worried soul!
