Investigating Severe Heat Sensitivity: Is it a Health Concern or Medication Side Effect?
Hello! I'm a 28-year-old female from Canada, standing at 5'4" and weighing 190 lbs. I am currently prescribed divalproex (valproic acid) and foquest (methylphenidate) as I manage bipolar disorder type 1 and ADHD. I experience significant heat sensitivity that affects my daily life. I’m uncertain if this is a common side effect of the medications I'm on. Unfortunately, both my psychiatrist and general practitioner have been unable to provide a definitive explanation. Sweating is not something I experience. When I’m outdoors for any length of time, my skin becomes flushed and damp. Additionally, I suffer from headaches and frequent nosebleeds. Oddly enough, I don’t perceive the heat itself; in fact, I feel rather chilly during these episodes. My smartwatch indicates my heart rate spikes to around 130 beats per minute when I report discomfort from headaches or nosebleeds. My husband mentions that my skin feels warm to the touch during these occurrences. My diet is predominantly healthy, filled with plenty of fruits and vegetables, and I primarily prepare meals at home. I engage in light exercise daily, and although I don’t drink alcohol frequently, I occasionally use CBD edibles to aid my sleep. I steer clear of over-the-counter pain medications and any supplements that might act as blood thinners. When I know I’ll be outside for extended periods, I avoid taking my stimulant medication. I make sure to hydrate well, consuming 4-5 liters of water each day, often supplemented with electrolytes. My attire typically consists of lightweight linen, and I also cover myself with scarves and hats. Sunblock is applied to exposed areas. This sensitivity has a considerable impact on my life—on particularly bad days, it only takes about 20 minutes for symptoms to emerge. I’ve had to miss work, skip family gatherings, and give up some hobbies, which is incredibly frustrating. Is this behavior indicative of a genuine health issue, or should I be concerned about my medications? I understand that weight plays a significant role, and I have been losing weight in a manner that feels positive for me. I appreciate any insights you may have. Thank you!

It's understandable to feel concerned about experiencing significant heat sensitivity, especially when it's affecting your daily life. The symptoms you're describing—such as skin flushing, a rapid heart rate during episodes, headaches, and nosebleeds—can indeed be distressing, and it's important to investigate their causes.
Explanation
Both divalproex and methylphenidate can have side effects, though heat sensitivity is less commonly mentioned. Divalproex can cause changes in temperature regulation for some individuals, and methylphenidate stimulates the central nervous system, which might lead to increased heart rate. However, your symptoms may also stem from other factors such as anxiety, hydration status, or even underlying medical conditions.
Despite your proactive approach to hydration, it’s vital to consider if the combination of medications and individual physiological responses is contributing to your discomfort. The flushing and lack of sweat may indicate a disruption in normal thermoregulation.
Next Steps
-
Track Your Symptoms: Keep a detailed diary of your symptoms, including when they occur, their duration, and any potential triggers. Note your hydration levels, activity, food intake, and any medications taken around the time of symptoms.
-
Evaluate Medication Timing: Since you've mentioned avoiding your stimulant medication before being outdoors, monitor how this specifically aids your symptoms. Consider discussing medication timing with your healthcare providers to find a suitable routine.
-
Monitor Heart Rate: Since your heart rate spikes during discomfort, try to measure this alongside your symptoms consistently. If your heart rate exceeds certain thresholds, this information can be crucial for diagnosis (typical resting heart rates range from 60-100 bpm).
-
Adjust Clothing and Conditions: Continue wearing lightweight fabrics, but test different clothing styles for comfort. If possible, avoid direct sun exposure as much as possible, and seek shade.
-
Hydration and Electrolytes: While you’re already consuming plenty of water, ensure that your hydration also supports your electrolyte balance, especially in hot conditions where you might sweat more despite not feeling hot.
-
Integration of Stress Management: Consider techniques such as mindfulness or relaxation exercises, which may help with how you perceive heat and stress responses.
-
Discuss with Providers: Prepare to revisit your psychiatrist or general practitioner with your symptom diary. You could also consider seeking a consultation with an endocrinologist or neurologist to explore underlying causes more thoroughly.
I'm here to support you as you navigate this challenge. It's admirable that you’re actively seeking solutions, and while it can be frustrating, minor changes and detailed observation might lead to breakthroughs in understanding your symptoms.

Will This Last or Can It Change?
I’m a 27-year-old male, standing at 170 cm and weighing 53 kg; nothing out of the ordinary there. About three weeks ago, after extended use of my headphones, I experienced a sudden loud ringing in my left ear. I quickly took off my headphones, and this intense ringing lasted only a few moments, but it was followed by a persistent lower ringing sound. Here are my symptoms: - I can't hear the ringing in louder environments such as at school or with windows open; it’s only noticeable in quiet settings. - The ringing tends to subside when I open my jaw, and I noticed it changes as I move my mouth, like when making a duck face. - Sleeping isn’t an issue for me. - The frequency of the ringing seems influenced by my stress levels. - Occasionally, I hear a hissing noise in my head when I turn it. - The sound diminishes when I focus my attention elsewhere. - I feel like my hearing has become more acute since this started. Though it’s manageable at the moment, the uncertainty surrounding my condition is really stressful. Previously, I used to sleep with headphones positioned awkwardly, so I suspect this may be linked to muscle tension or issues with my jaw. How can I determine whether this condition is permanent? What steps can I take to protect my hearing?
Accidental Eye Injury from a Needle
At 16 years old, I experienced an incident while attempting to extract a small blackhead from my nose using a needle. Unfortunately, I accidentally jabbed the needle into my eye. Initially, it seemed like the needle didn’t penetrate deeply, but the pain was considerable at the moment, and while it has since diminished, I still feel some discomfort. My eye also has an itchy sensation. I am concerned about whether injuries of this nature can lead to lasting damage or if they typically heal over time. Additionally, I would like to know if there are specific symptoms I should monitor as I recover.
Seeking Guidance on Hydroxyzine Discontinuation and Dosage Adjustment
I've been using hydroxyzine at a dose of 25-50 mg daily for the past five years. I have a dental surgery scheduled this year that will require IV sedation, followed by a week of doxycycline treatment. As such, I'm attempting to eliminate my need for hydroxyzine before then. While numerous sources suggest that withdrawal is minimal or nonexistent, my experience contradicts this; the one time I tried to stop taking it abruptly, I suffered severe itching along with heightened insomnia and anxiety. I'm looking for some guidance on this matter. Additionally, is it advisable to split the 25 mg tablets in order to taper my dosage gradually? For context, I'm a 33-year-old male, standing 5'7" and weighing 240 pounds.
Unexpected Tingling Sensation in My Left Hand and Mouth
Today was quite unusual for me, and I’m still trying to figure it all out (23F). While I was unloading groceries from my garage, I suddenly noticed an odd feeling in my left index finger—it almost felt numb. Initially confused, I began tapping my finger because this sensation was entirely new to me. I then moved to the sink to run warm water over it, hoping it might help. To my surprise, the tingling sensation spread throughout my entire left hand and into my forearm, although it didn't fully extend to my whole arm. I’m certainly no expert in medical conditions, but it seems like it might be related to some kind of nerve issue? Perhaps I twisted my wrist awkwardly while carrying one of the bags, and it decided to respond dramatically, haha. Additionally, I’m on birth control, and I have heard that blood clots can be a concern, with side effects varying from person to person. My physician once mentioned that tingling could also be a symptom and recommended that I keep active instead of being sedentary all day. I have previously felt tingling in my feet when I first started the medication, and recently, it seems to manifest more in my arms if I’ve been resting on them for extended periods. While I didn’t want to jump to conclusions and think it could be a stroke—since I didn’t experience the majority of the typical symptoms—I did find the sensation in my teeth to be peculiar and rather intriguing 😭.
Experiencing Full-Body Numbness
At just 14 years old and standing at 173 cm tall with a weight of 89 kg, I find myself without any ongoing health problems or medication. Despite this, I frequently encounter a disconcerting numbness throughout my body. This sensation, notably felt in areas such as my scalp and legs, leaves me feeling detached, as if the typical pleasant tingling or sensory feedback I usually experience is absent. It’s as though my body is not responding as it should, leading to a perplexing and unsettling feeling.
