Nodular Melanoma or Blood Blister: Seeking Insight

7/10/2025, 1:20:19 AMMale25-34

Subject: Nodular Melanoma or Blood Blister? Hello, I am a 23-year-old female, weighing 210 pounds and standing at 175 cm tall. I only have partial knowledge of my family's medical history, and cancer has never been mentioned before. I spend time outdoors and do not have any known allergies. The only medication I am currently on is Ozempic. Recently, I've discovered a lump on my left buttock. I first noticed this swelling a few months back, but it wasn’t painful and was in an area I didn’t frequently observe, so I initially dismissed it. However, I've observed it has increased in size. When I took a closer look using a mirror, I was startled to see its very dark coloration. As a paramedic, I should have been more cautious, but I mistakenly assumed it was just a typical blood blister and, using an IV needle, I poked it. Unfortunately, this was unhelpful; it bled but did not reduce in size, and it seems to have become more pronounced since then. The mass feels hard, has irregular borders, and exhibits a dark red to purple hue, with a touch of pink. Due to its location, it’s difficult to assess the size accurately, but I estimate its circumference resembles that of a penny and it protrudes about 4 mm. It is immobile and causes slight discomfort when I sit down. I could really use some guidance on this issue as I wait for my doctor's appointment on Wednesday.

It's understandable to feel concerned about a lump that has changed in size and appearance, especially given your background as a paramedic. While I can't provide a diagnosis, I'll help you understand some key points regarding the lump you're describing and guide you on what to focus on as you await your doctor's appointment.

Main Points:

  1. The characteristics you've described—irregular borders, hard texture, dark coloration, and tenderness—are noteworthy and should be taken seriously.
  2. Nodular melanoma is a type of skin cancer that can present with similar features, but not all lumps are cancerous. Blood blisters, cysts, or benign lesions are other possibilities.
  3. Monitoring and documenting any changes before your appointment will be helpful for your doctor.

Explanation:

The growth on your buttock that is dark, irregularly shaped, and has increased in size over time raises valid concerns. Skin changes, especially those that persist or worsen, warrant attention. Nodular melanoma tends to be raised, darkly pigmented, and may vary in color, whereas blood blisters are typically more uniform and can change with pressure or friction. Your observation of the lump’s persistence and increase in size is significant.

Next Steps:

  1. Document Changes: Keep a note of any changes in the lump’s size, color, or any new symptoms (like pain or itching) leading up to your appointment. Taking pictures can be helpful as well.

  2. Avoid Further Manipulation: Since your attempt to drain the lump was unsuccessful, it's crucial to avoid further irritation. Do not attempt to poke it again, as this may lead to infection or further irritation.

  3. Monitor Symptoms: Pay attention to any additional symptoms. If you experience significant pain, swelling, fever, or other concerning symptoms before your appointment, consider seeking urgent medical evaluation sooner.

  4. Prepare for Your Appointment: Write down your observations, including when you first noticed the lump, any changes you've seen, and your medical history, including the use of Ozempic. This will help your doctor assess the situation more effectively.

  5. Stay Calm and Patient: It’s normal to feel anxious, but try to stay calm until your appointment. Many skin conditions are treatable, and waiting to get a professional evaluation is the best course of action right now.

Your vigilance in noticing these changes is essential, and I wish you the best for your upcoming appointment. If you have more questions or need further clarification, feel free to ask.

I am a 27-year-old woman, standing at 1.5 meters tall and weighing 46 kilograms. Since I entered my second trimester ten weeks ago, I have been experiencing several concerning symptoms, including fatigue, a fluttering sensation in my heartbeat, nausea, frequent headaches, and episodes of shortness of breath. My heart rate has spiked at times, reaching between 160 and 180 beats per minute. I have undergone a variety of tests, including D-dimer, thyroid function tests, a full blood count, and ferritin levels. Additionally, there were ultrasounds of my thyroid and heart, along with examinations for pheochromocytoma, an echocardiogram, and an electrocardiogram, all of which returned normal results. Despite this, my symptoms continue to persist three months after giving birth. Furthermore, my Huawei Band 9 has been reporting arrhythmia or premature ventricular contractions (PVC) as many as 15 times during the night. I am seeking urgent assistance, as I have already consulted several healthcare professionals without resolution.

Recovery from De Quervain’s Tendon Surgery

Hello! I’m a 22-year-old female, and I underwent De Quervain’s tendon release surgery about 15 hours ago. Currently, I’m experiencing numbness from my middle finger to my thumb, starting from the middle of my forearm. The procedure was conducted under local anesthesia, and while it wasn’t unbearable, there were moments of discomfort throughout. Is it typical to have lingering numbness in such a significant area of my arm and hand? I plan to reach out to the office when they open in the morning, but I wanted to gather some insights from anyone who might be familiar with this. I was informed that the numbness should subside within 5 to 6 hours. Additionally, my surgeon mentioned that there are two anatomical variations in my wrist—though I can’t quite recall one of them; the other was an unusual growth of muscle in the tendon, which he noted was problematic but successfully addressed. I have complete trust in my surgeon (let’s hope he doesn’t see this!) and just wanted to see if others have had similar experiences before I consult someone tomorrow.

Experiencing an Abdominal Pulse?

At 29 years old, I’ve noticed a pronounced sensation of my heartbeat in my stomach while lying down. Although I’m aware that searching for symptoms online is not advisable, I couldn’t help myself. The mention of an Abdominal Aortic Aneurysm (AAA) certainly alarmed me, especially considering my high-pressure role as a nurse. I don’t smoke and have maintained sobriety for the past two years. Recently, I sought medical attention in the emergency room due to an incident of sinus tachycardia during my shift. My chest X-ray results were normal, and while the lab tests showed a slight dip in white blood cell count at 4.21, everything else appeared fine. I have been on metoprolol 50 mg XR for nearly a year. Should I consider undergoing another evaluation?

Persistent Yellow Stools: What to Discuss with Your Doctor

I'm a 26-year-old female and have a doctor’s appointment this coming Friday. I’m seeking advice on what tests I should consider discussing during my visit. Previously, I was diagnosed with moderate fatty liver, and gallstones were also identified, but since they didn’t present any immediate issues, my doctors didn’t express concern at that time. Lately, I've been experiencing persistent yellow stools that tend to float, appearing shortly after I eat. Currently, I’m not in any pain, nor do I have any additional symptoms. I’m curious about the potential causes of this and what I should ask my doctor to examine during my appointment. A month ago, I had a blood test that returned normal results, aside from elevated ALT and AST levels. My bilirubin levels were normal as well. Does this indicate a possible progression of my fatty liver condition? I've been researching online, and many sources mention cirrhosis, which is quite worrying for me.

Enlarged and Tender Submental Lymph Node Following Perioral Dermatitis

I am a 27-year-old male, standing at 180 cm tall and weighing 75 kg. I have a history of eczema, and about three to four weeks ago, I experienced an outbreak around my mouth. At that time, I also noticed that the submental lymph node in my neck had become swollen. After administering treatment with steroids and antibiotics, I thought the issue had resolved. However, a week ago, the eczema returned, and so did the swelling of the lymph node. Today, I have observed a significant increase in both the size and hardness of the lymph node, along with persistent pain. While I am pleased to say the eczema is now completely gone, the painful and swollen lymph node remains a concern. I consulted with a physician today who prescribed antibiotics and anti-inflammatory medication, but I can’t shake the feeling that there may be a more serious underlying issue. I am seeking your insights: would it be wise to pursue a second opinion? Has anyone else encountered a similar situation? Thank you for your assistance.
