Significant Disparity in Foot Temperature and Coloration

2/10/2026, 9:50:39 AMMale25-34

Greetings, I am a 22-year-old female weighing 112 pounds. Throughout my life, I've experienced cold feet quite easily, but I've recently observed that my right foot is significantly colder than my left. Additionally, the toes on my right foot sometimes appear purple, while those on the left remain their normal color. I'm curious about what may be causing this and whether it warrants any concern. Currently, I am prescribed 20mg of Adderall in immediate-release form, which I take twice daily, along with a combined hormonal birth control pill. Recently, I was also taking oral phenylephrine daily for a week due to a sinus issue localized to my right side; however, I discontinued this medication just yesterday after reaching the one-week mark. This sinus condition emerged following my recovery from a cold, which is now improving. I'm uncertain how long this discrepancy in temperature between my feet has existed; it could have been ongoing for a while, but I only recognized it now since I've always dealt with cold feet.

It sounds like you are experiencing a concerning change in your foot temperature and coloration, specifically with your right foot being significantly colder and having a purplish hue compared to the left. Here's what you need to know:

Main Points:

  • The difference in temperature and color in your feet could indicate issues with blood circulation, nerve function, or even responses to medications.
  • Given your current medications and recent sinus issue, it's important to monitor these symptoms and take specific actions.

Explanation:

Cold feet, especially when accompanied by a color change (like your right toes appearing purple), can suggest reduced blood flow to that area. Some common causes may include:

  1. Circulation Problems: Conditions that affect blood flow, such as peripheral artery disease or Raynaud's phenomenon (where blood vessels narrow in response to cold or stress).
  2. Nerve Issues: Conditions that impact nerve function can also lead to temperature changes in extremities.
  3. Medication Effects: Adderall can increase peripheral vasoconstriction (narrowing of blood vessels), which might be affecting blood flow to your feet.

Since you have noticed this change, it is important to address it promptly.

Prioritized Next Steps:

  1. Keep Warm: Ensure your feet are warm by wearing socks and staying in a comfortable temperature environment.
  2. Monitor Symptoms: Pay attention to any additional changes, including if you experience pain, numbness, or if the color change worsens.
  3. Avoid Strain: Limit exposure to cold environments and stressors, as these can exacerbate symptoms.
  4. Self-Observation: Note any additional symptoms like swelling, pain, or changes in sensation in your foot. Keep track of them for a week, including any patterns related to your activity or medication.
  5. Reassess Medications: If symptoms persist, consider discussing your medication regimen, especially the recent use of phenylephrine, as it could affect circulation.

Please remember, while these steps can help monitor and provide initial comfort, persistent or worsening symptoms should be evaluated. If you experience severe symptoms like increased pain, numbness, or significant change in foot coloration, consider seeking further evaluation. Your health and peace of mind are important, so don’t hesitate to follow up on your symptoms. Let me know if you have any further questions or need additional information!

Should I be Concerned About a Rabies Vaccine?

On Saturday night, I had a minor incident with a dog on the street. The animal, possibly just a playful puppy full of energy, jumped at me unexpectedly and caused a sharp sting in my right leg. The dog's owners appeared indifferent to the scene, which made me even more frustrated, but the sudden pain prompted me to move quickly past them. On inspecting the injury, I discovered a small puncture wound—likely from either a tooth or claw—that penetrated my jeans. Now, there’s a bruise forming in that area. I had received my Tdap booster shot back in November, and I initially reassured myself that the chances of rabies transmission were very low due to a few factors: it was a pet, the injury was minimal and occurred through clothing, and here, it’s a legal requirement for pet vaccinations. However, I’m beginning to feel anxious about the situation. Questions fill my mind, like whether the dog was too young to have received its vaccine, given the significant force of the jump. I find myself puzzled—am I simply being overly cautious, or should I genuinely seek medical advice? It’s hard to tell if my worry is warranted or just my imagination running wild!

Seeking Answers: Unraveling a Medical Enigma

I will aim to express my situation clearly and succinctly. Please bear with me as I share my distressing experiences with a complex and progressive condition that remains without a diagnosis. My health issues emerged around April or May of the previous year, beginning with intense spasms in the arch of my left foot that caused my big toe to involuntarily pull downward, rendering it immobile and intensely painful. Soon after, I started experiencing muscle twitching, which initially was confined to my left foot but has since affected both feet and, by October, spread throughout my entire body, including my tongue. Additionally, I have developed tremors that exacerbate with muscle use. Accompanying these symptoms, I have witnessed significant and uneven muscle atrophy that originated in my hands and feet and has now progressed to include all of my limbs, chest, spine, hips, the inner thighs, the left side of my abdomen near my ribs, and my neck. This degeneration has severely compromised my physical stability, leading to falls, trembling legs on stairs, and an overall sense of unsteadiness. I also endure ongoing deep pain in my upper and mid-spine. My background includes chronic pain from multiple abdominal surgeries, culminating in a colectomy in 2016. While I manage some of this pain with fentanyl patches and use morphine on occasion, these medications do not alleviate the spinal discomfort. I find relief only from THC cannabis and ibuprofen gel, with the former having been recommended by another chronic pain sufferer. In June, endocrinology determined that I have autonomic dysfunction, resulting in debilitating symptoms such as vomiting and episodes resembling crashes when I’m in a bath. By December, I began experiencing difficulties with swallowing and breathing. Solid food now has difficulty moving through my system, making meal replacement drinks necessary. I find that reclining at about 40 degrees improves my breathing, while any position closer to upright or flat leads to shortness of breath. Even minor physical activities induce intense breathlessness and excessive sweating. A recent lung function test recorded a Forced Vital Capacity (FVC) of 3L, categorized as "satisfactory" for the moment. In September, I also experienced new urinary symptoms at night, with increased urgency and frequency that I had never encountered before. Intermittently, I have been faced with pituitary axis dysfunction that affects several hormones, including cortisol levels. While it may not be pertinent, I have consistently shown elevated IgM levels since 2022 (around 2.6–3.0) and chronically higher lymphocyte counts (typically in the 5–7 range). Notably, I’ve had instances of red blood cells appearing in my blood tests on three occasions in 2024. Serological tests have not pinpointed any recent viral illnesses (such as CMV, EBV, or HIV). Currently, I am under the care of a neuromuscular specialist who has recorded several observations: • Weakness on the left side of the body • Enhanced reflexes in the upper limbs • Postural tremors • Inability to spread my toes on the left foot • Weakness in hip flexion bilaterally • Fasciculations and tremors in the tongue MRI examinations of my brain and spine with contrast returned normal results, although a previously noted atypical hemangioma in the third vertebra was found to have resolved itself. Despite comprehensive testing for paraneoplastic antibodies returning negative results, I understand that about 40% of cases in this category show no detectable antibodies. Testing for Lyme disease has been negative. Blood tests concerning neuromuscular conditions such as MG, CIDP, and MMN have also yielded negative results. Levels for copper and lead are within normal ranges. Endocrine-related tests have also shown no paraneoplastic activity. My free light chains are increasing but remain within the normal range, therefore indicating no paraprotein presence. Autoimmune testing has produced negative results for both ANA and ds-ANA. A drop in my B12 levels was recorded last October; while injections provided temporary improvement, switching to oral supplements caused a rapid decline again within a month, raising concerns over absorption issues. Nevertheless, my B12 levels aren't low enough to directly explain my symptoms but may exacerbate them in some way. Results from Nerve Conduction Studies (NCS) and Electromyography (EMG) indicated the presence of Peripheral Nerve Hyperexcitability Syndrome, evidenced by widespread fasciculations, which has led to the initiation of lamotrigine treatment. As of now, I have not undergone genetic testing or a lumbar puncture for cerebrospinal fluid analysis. I am currently waiting for an MRI of my lower limbs to evaluate the extent of muscle wasting. Additionally, I have been referred for assessments in swallowing by a speech and language therapist, and a neurophysiotherapy specialist, along with an occupational therapist. Interestingly, there appears to be a potential familial pattern among my children, who exhibit abnormalities in coagulation, muscle weakness, and vitamin deficiencies. If anyone can relate to my situation, has had similar experiences, or has suggestions for avenues I might explore, I would greatly appreciate your insights. — C (35-year-old Female, UK)

Swelling on the Top of My Foot After Hitting the Couch

I’ve noticed some swelling on the dorsum of my foot, which was roughly the size of a golf ball about an hour ago, but it seems to have reduced to about half that now. What steps can I take to address this issue, and how likely is it that this will impact my exam scheduled for tomorrow? I have completed the physical exam, and I still need to undergo blood and alcohol tests, along with a chest X-ray, auditory, and visual assessments. It seems improbable that this injury will affect my medical examination tomorrow, right?

Should You Be Concerned About Arm Discomfort After a Blood Draw?

Earlier today, I had my blood drawn and I'm a 20-year-old female accustomed to regular testing due to my POTS and chronic iron deficiency. However, I've never experienced this before. The moment the needle entered my arm, I felt a sudden tingling sensation throughout my hand and forearm, similar to pins and needles. Even after several hours, the tingling persists, accompanied by a slight numbness. I also notice that performing tasks that require lifting objects makes that arm feel especially weak and numb. Is this a typical reaction? If so, how long does it usually last? It’s an extremely annoying sensation, and I’m eager to find relief.
