Nodular Melanoma or Blood Blister: Seeking Insight
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:
- The characteristics you've described—irregular borders, hard texture, dark coloration, and tenderness—are noteworthy and should be taken seriously.
- 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.
- 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:
-
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.
-
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.
-
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.
-
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.
-
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.

Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
