Unusual Mark on Thigh: Seeking Answers
I am a 31-year-old female, standing at 5 feet 4 inches tall and weighing 135 pounds. I identify as Caucasian and reside in South Carolina, USA. For the past couple of months, I have been noticing a peculiar spot on the front of my upper thigh. It doesn’t cause any itching or discomfort, but it’s visually concerning. Initially, my doctor suggested it might be ringworm, and I followed their advice, applying the prescribed ointment for over eight weeks. Unfortunately, it did not show any improvement and has even expanded in size. Now, I am starting to wonder if it could be something like Lyme disease, given that mosquitoes, in addition to ticks, can transmit it. Living in the South, I’m accustomed to encountering plenty of mosquitoes. I’m contemplating whether I should seek the expertise of a dermatologist for a biopsy or another form of evaluation. This situation is increasingly frustrating, especially with the summer season in full swing, as I feel self-conscious about wearing a bathing suit. I am eager to find a solution and prevent this from getting worse.

It’s understandable to feel concerned about an unusual mark on your thigh, especially since you’ve already sought treatment without improvement. Let’s break down the situation and outline some actionable steps for you.
Main Points
- An unusual spot that hasn’t responded to treatment for ringworm may need further evaluation to identify its cause.
- Lyme disease primarily results from tick bites rather than mosquito bites, and the mark on your thigh could be related to several other conditions.
- Consulting a dermatologist is a strong next step to properly assess the mark.
Explanation
You mentioned that the spot on your thigh has been present for a couple of months and has not improved with the antifungal treatment suggested for ringworm. Since it has also increased in size, this is a valid reason for concern. Conditions to consider include dermatitis, an allergic reaction, psoriasis, or other skin conditions, rather than just ringworm or Lyme disease.
Lyme disease is transmitted through ticks, not mosquitoes. If you had a known tick bite and develop a rash in a specific pattern, that may increase suspicion, but given the context, it’s not the most likely cause for your thigh mark.
Next Steps
- Consult a Dermatologist: Schedule an appointment with a dermatologist to get a professional evaluation of the mark. They may perform a biopsy or other tests to clarify what the lesion is.
- Document Changes: Keep a record of any changes in the spot’s appearance, including size, color, or texture. Take pictures for reference if it’s necessary to examine it over time.
- Avoid Irritation: While waiting for your dermatologist appointment, try to keep the area clean and avoid any irritants like heavy creams or sprays, which might worsen the condition.
Taking these steps can help you get closer to a diagnosis and appropriate treatment. Remember, it’s perfectly normal to feel uneasy about something like this, and you’re being proactive by seeking answers. Keep me updated on how it goes!

Understanding a Sore Throat
I am a 24-year-old individual, standing at 5 feet 9 inches and weighing 132 pounds. Occasionally, I smoke cannabis before sleeping. For the past week, I have been experiencing a painful throat, although I do not feel unwell overall. The discomfort becomes particularly noticeable when I attempt to swallow, and at times, it seems to radiate towards my ear. Additionally, I've noticed that my tongue appears unusually pale, and there seems to be an increase in mucus production. To investigate further, I used a cotton swab to examine my tonsils, which revealed a slight redness at the tip of the swab. Recently, I embarked on a new romantic relationship, so I'm a bit concerned it might be linked to oral activities. Alternatively, could it stem from allergies or post-nasal drip? I welcome any insights or suggestions you may have!
Unexplained Skin and Vascular Symptoms
A healthy 37-year-old woman, who has a medical history of gastroesophageal reflux disease (GERD) and migraines with aura, is grappling with what she believes might be a viral infection that has persisted for approximately five weeks. She is struggling to find any information online that resembles the rash she is experiencing. Her primary care physician (PCP) dismissed her condition as mere generalized redness rather than a true rash and conducted a range of tests, including complete blood count (CBC), metabolic panel, C-reactive protein, and autoimmune screenings, all of which yielded normal results. Although a dermatology appointment is on the horizon, the wait time is several weeks. The rash is present on her face, lips, neck, arms, legs, hands, and feet, and she is also experiencing a tingling and burning sensation in her extremities. She believes there could be a vascular issue at play, as she has noticed circular spots aligning with her blood vessels. Additionally, her veins have become more visible throughout her body, including on her face, and they are sensitive to touch, causing discomfort. Some veins on her legs have burst, resulting in small bruises. Recently, she has developed numerous small blisters on her hands and has previously shared images in another thread for reference. Feeling increasingly distressed, she has encountered skepticism from her PCP, who attributed her symptoms to a herpetic virus and advised her to allow the condition to resolve on its own. A month has passed, and her veins continue to look abnormal while the burning sensation persists, now accompanied by painful blisters. She is questioning whether her symptoms could be indicative of a wart or an HPV-related virus, as she feels lost and uncertain. Any insights regarding the relationship between viral infections and vascular symptoms, or potential mild vasculitis, would be greatly appreciated.
10-Year-Old Struggling with Persistent Cough
My child, who is only ten, has been battling a cough for the past three weeks. We visited her physician, who suspected it might be a viral infection and advised us to return if her condition deteriorated. Unfortunately, her symptoms intensified over the weekend, prompting a visit to urgent care where she was prescribed steroids and antibiotics. An X-ray was performed, and while it ruled out pneumonia, the doctors believed she might be experiencing bronchitis. Now, two weeks have passed, and her cough persists to the extent that it disrupts her sleep. Each time she coughs, she's left gasping for breath, which is distressing for both her and our family. Today, we returned to her doctor, who conducted a respiratory viral panel testing for 22 different viruses, yet every test result came back negative. This situation is unprecedented for us and has been particularly alarming, especially during the nighttime hours. We’re at a loss about what steps to take next. Where should we go for further assistance? What additional tests should be considered? How can we effectively support her through this?
Seeking Guidance on Persistent Health Issues
I’m a 43-year-old man, standing at 5'10" and weighing 293 lbs. Since the beginning of 2023, I have been enduring recurring chest pain accompanied by discomfort in my left arm. In August 2023, these symptoms prompted me to visit the emergency room. After undergoing numerous tests including EKGs and blood work, the medical team confirmed my heart appeared healthy. They recommended an ultrasound and a CT scan to further investigate. The results showed no arterial plaque, and I was given the all-clear. While the intensity of the pain subsided, it continued to reappear. By January and February, I found myself returning to the ER once again, this time experiencing sharp pain beneath the skin around my left breast, in addition to a burning sensation in my stomach that resembled heartburn but felt different. After extensive testing, I was still informed that there were no significant issues and was advised to consult a cardiologist. Following my visit, the specialist reviewed my August CT scan with contrast and assured me that everything looked good for at least the next decade. I was encouraged to explore meditation for relaxation and also to proceed with gallbladder removal, which had been scheduled for June due to the presence of sludge and an elevated HIDA scan score. The gallbladder surgery was seen as a potential solution to improve my condition. Currently, I am still grappling with chest discomfort, pain extending to my neck and down my left arm, along with persistent stomach issues. Despite the myriad tests I have undergone—including ultrasounds, multiple blood analyses, EKGs, stress tests, and a CT scan with contrast—doctors have not pinpointed the exact cause of my suffering. I have consulted various specialists: rheumatologists, my primary care physician, and a spine expert who performed several MRIs on my neck and back. Treatments have included injections aimed at alleviating symptoms in my thoracic spine discs, and I'm expecting another injection to address a possible pinched nerve in my neck. I remain hopeful that this might be the source of my pain and bring me some relief. This ordeal is incredibly frustrating, severely impacting my quality of life, and I find myself running out of options. The feeling of being shuffled from one doctor to another with no clear answers is overwhelming and disheartening.
Should I Be Worried About These Symptoms?
At 28 years old, I have been suffering from persistent headaches and migraines that have lasted for 15 years. It all began with a single headache that has since become a constant presence in my life. My initial MRI, taken shortly after the onset of my headaches, revealed a few spots in the central region of my brain. The doctor explained that these irregularities were likely related to my condition, allowing me to view the scan for further understanding, and I was sent home with a copy of the images. A few years later, I underwent a second MRI. Although I didn’t get to review the results, I was informed that they appeared similar to the previous one. Years passed, and a new neurologist prescribed Emgality for migraine relief, which significantly reduced the frequency of my headaches. However, as time went on, the effectiveness of the treatment diminished, leading my neurologist to transition me to Qulipta. I have now been on Qulipta for six months, but unfortunately, it hasn’t helped alleviate my daily headaches, and I continue to experience at least one migraine each week. In recent years, I’ve noticed additional troubling symptoms that I suspect may be associated with my migraines, and I am unsure whether they warrant concern. These symptoms include: - Daily ear ringing, often accompanied by pressure on the right side of my head and temporary hearing loss in that ear. - Episodes of dizziness when standing, frequently with accompanying vision and hearing disturbances, along with muscle fatigue (this new symptom has emerged within the past 2-3 months). - Instances of memory problems, including difficulty constructing sentences or recalling words, and sometimes struggling to comprehend spoken language, which often sounds nonsensical to me. - Vision disturbances caused by bright lights that impair my ability to see, which I understand can be a migraine symptom, but it sometimes occurs independently of a migraine. I've observed that these symptoms have become more severe and frequent over the last year. When I discussed my concerns with my neurologist, they simply attributed these issues to migraine symptoms and switched my medication to Ajovy, which I have yet to try, following the recent cessation of Qulipta. An additional incident that may hold significance occurred around the onset of my headaches. During a day spent with a friend, while we were laughing and enjoying ourselves, I suddenly felt the right side of my face droop. I calmly stated that I thought I might be having a stroke. Although I’m uncertain if that was indeed a stroke, it was a bizarre experience that hasn’t reoccurred since. Currently, my medications include Apri birth control and marijuana. I am increasingly worried about the rapid progression of my symptoms, but I feel uncertain about how to proceed regarding medical consultations or necessary tests. I do have an MRI scheduled for next month, which I hope will shed more light on my situation.
