Seeking Guidance for Persistent Rash on My Foot
I am a 26-year-old female and have been dealing with a rash located on the top of my foot for nearly two months. Given my lifelong experience with eczema, I didn’t initially react with alarm to this new irritation on my foot. The rash extends slightly between my toes, which is a new development for me. When I mentioned this to a friend, she suggested it might be athlete’s foot. In response, I decided to use ketoconazole shampoo that had previously been prescribed for a different issue. However, there was no noticeable improvement in the rash. While it occasionally itched, the discomfort was not severe. In an effort to address the situation, I also began applying an over-the-counter terbinafine cream, thinking the shampoo might not be sufficient. Unfortunately, this too failed to yield any results. As the rash progressed, I started to observe pustules forming, which raised my concern about a possible infection. This prompted me to visit a walk-in clinic, which turned out to be quite a frustrating experience. There, I received a prescription for oral fluconazole along with a prednisone injection. This occurred about a month after the rash first appeared. Although I’m not entirely sure what contributed more to the improvement at that stage, I noticed some positive changes initially; however, the rash returned soon after. In my search for a more definitive solution, I consulted a dermatologist who prescribed ketoconazole cream and mupirocin ointment, advising me to use both treatments for a two-week regimen. After completing the first week, I have yet to see any improvement, and I’m beginning to worry that this might be indicative of a more serious condition. I’m now contemplating whether consulting a podiatrist could be a more appropriate next step. Any advice or suggestions would be greatly appreciated!

It sounds like you’re dealing with a persistent and frustrating rash on your foot that hasn’t responded well to various treatments. Given your history with eczema and the new symptoms like pustules, it's important to consider a few possibilities while remaining focused on finding relief.
Explanation
The rash could be due to several factors, including:
- Eczema Flare: It's possible that the stress of a new location, such as your foot, has triggered eczema.
- Fungal Infection: Your friend suggested athlete’s foot, which is a common fungal infection, and it can sometimes cause pustules.
- Bacterial Infection: The development of pustules might indicate a secondary infection, especially if the skin barrier is compromised.
- Other Dermatitis: Conditions such as contact dermatitis or psoriasis may also manifest as rashes.
Since you have already tried several treatments targeted at both fungal and bacterial issues without sustained improvement, it's understandable that you're feeling concerned.
Next Steps
-
Continue with Treatments: Follow the dermatologist’s prescribed regimen of ketoconazole cream and mupirocin ointment for the full two weeks. Make sure to apply them as directed and avoid mixing other treatments during this time, as changing regimens could disrupt healing.
-
Monitor Symptoms: Keep a diary of your symptoms, noting any changes in the rash, itching, and whether there are triggers that worsen it. This information can help you and your healthcare providers identify patterns.
-
Review Foot Care:
- Moisturize: If eczema is a concern, ensure you're properly moisturizing your foot—consider a thick, fragrance-free emollient after washing.
- Keep Dry: Make sure to keep your feet dry, especially between the toes, to discourage fungal growth.
-
Consider a Podiatrist: If there is no improvement after two weeks or if symptoms worsen, seeing a podiatrist could be beneficial. They can provide targeted examination and treatment options since they specialize in foot issues.
-
Follow-Up with Dermatologist: If you don’t see improvement at the end of the treatment regimen, returning to the dermatologist for further evaluation may be necessary. They might explore alternative diagnoses or additional testing if needed.
-
Avoid Self-Medicating: Avoid using new over-the-counter products without consulting your dermatologist or podiatrist to prevent irritation and confusion in your treatment plan.
Reassurance
It’s completely reasonable to feel concerned given the duration and persistence of the rash, especially with the changes you've observed. It's clear that you are actively seeking solutions, and hopefully, the combination of sticking with your dermatologist's prescribed treatments, carefully monitoring your symptoms, and considering further specialist input will lead you toward better skin health. Stay proactive, and don't hesitate to reach out for further help when needed!

Seeking Your Insights and Advice
I've conducted my research and generally understand where things might be headed; however, there are a few discrepancies that I'd like to address, and I'd appreciate additional perspectives. The presence of anemia is evident, and I am looking into further potential causes. My blood tests indicate low levels of RBC, hemoglobin, hematocrit, MCH, and relatively low MCV. Most notably, although my platelet count is generally high, my LDH is flagged, and my ESR is notably elevated at 90. (I am aware that this could indicate various issues, right?) Lymphocytes and neutrophils appear normal, while my monocyte levels are acceptable but my WBC count is slightly on the lower side. From a physical standpoint, there are no visible infections. In the last four months, I've undergone a colonoscopy and have seen an ENT for screenings and a minor procedure on my nose. Here are some symptoms I’ve been experiencing: - I often have night sweats, which have intensified recently to the point of soaking through occasionally. - I frequently feel fatigued, struggling to wake up in the mornings; once I'm awake, I tend to feel reasonably okay. I've also lost a considerable amount of weight (approximately 50 pounds over the past two years), although some of that was expected due to my sobriety. - This past year has brought attention difficulties, likely exacerbated by stressful life events. - I’ve had sporadic skin rashes that have always been treated as eczema when necessary. - My digestive health has been mostly stable with only minor concerns. - Recently, I’ve noticed two swollen lymph nodes in my neck, persisting for 2-3 weeks; one experiences slight discomfort in certain positions, but is otherwise pain-free. - Additionally, I’ve been dealing with more frequent nosebleeds, originally self-inflicted, which have become more prevalent recently. I noticed some black flecks in my blood when it had previously crusted, which I’ve linked to my low blood levels. Most concerning was when my nasal bleeding caused a blockage in the sink drain—a clear sign that this isn't typical. During the COVID period and the subsequent year, I also experienced significant hair loss around my hairline, which I initially associated with alcohol consumption and related skin issues. Thankfully, both hair loss and skin problems have mostly resolved since I stopped drinking. I have scheduled appointments for this week, but I’m curious if any of these symptoms warrant an immediate trip to the emergency room. Generally, I feel fine aside from the fatigue stemming from my anemia. If anyone has insights or advice, I would greatly appreciate your input!
Intense Discomfort Beneath the Right Kneecap
I'm a 41-year-old female, and for the past week, I've been experiencing significant discomfort in my right knee. I can walk and sit comfortably, but kneeling has become quite painful. Any pressure on the knee, such as leaning against a desk or object, produces severe discomfort. Once the pain sets in, even lightly touching the area sends sharp waves of pain. The sensation resembles a burning ache, similar to that of a burn or raw skin, yet the skin itself isn’t the source of the pain. It intensifies when my leg is bent in such a way that it makes contact. This isn't my first encounter with knee issues; however, I do have myofascial pain syndrome and fibromyalgia, which occasionally lead to mild tendinitis in my wrists and elbows. Nevertheless, this particular sensation feels too focused and acute to fall into the category of my usual discomfort. I observe no signs of redness or swelling, nor can I recall any incident where I could have injured it. There might be a slight sensation of pain radiating down my leg. Interestingly, I don’t experience any discomfort when my leg is resting or while walking normally, but bending the knee or crouching triggers pain after a brief period.
Question Regarding Expiration Date of Hydrocodone-Acetaminophen 5-325
Hello everyone, I’m reaching out with a question regarding the expiration date of my hydrocodone-acetaminophen prescription, which I obtained last year on May 26, 2024. The bottle indicates a discard date of May 26, 2025, which is only a year from the date of issue. I still have several tablets left that I kept for emergencies, and now I find myself in need of them after a fall from my dirt bike that has left me in considerable discomfort. Can I safely use these remaining pills? I have always been cautious about medications, so I would greatly appreciate any insights you can provide. Thank you!
Awoke to a Sharp Pain in My Neck
This morning, I, a 21-year-old female, found myself in discomfort, waking up with a severe ache in my neck. Turning my head has become a challenge; I can barely lower it or look upward, and any attempt to rotate it to the left is met with excruciating pain. The only minimal movement I can manage is a slight nod and a gentle lean to the right. Despite applying a pain relief gel and using a heating pad, relief remains elusive. The pain has persisted for five hours now.
Recognizing a Medication-Induced Low Blood Pressure Emergency
Hello! My partner, who is 27 years old and identifies as AFAB and uses they/them pronouns, was recently given a combination of medications: benztropine and clonazepam for treating tardive dyskinesia and dystonia, along with propranolol. Though we were informed that these medications could be safely combined, we have been cautious and taking them at different times. Just a short while ago, they came upstairs to check in with me, mentioning that they felt significantly dizzy and faint. I noticed their face seemed somewhat cold and perhaps a tad pale, although the lighting made it hard to be certain. After lying down with their feet elevated against the wall, their face seemed to warm up. We suspect that the dizziness might stem from low blood pressure caused by the mix of these medications. How can we determine if this situation qualifies as an emergency? We would prefer not to burden emergency responders or incur unnecessary expenses if this isn't a critical issue. Appreciate your guidance!
