Changes in a Puncture Hematoma: From Injury to New Concerns
Summary: An injury caused by a tack remover resulted in a large internal bruise that has since left a hard lump in my leg. Recently, after bumping it, the lump shifted position and became smaller. Last year, while trying to clear out screw holes on my metal roof in a rushed manner, I improperly wielded a tack remover. The tool slipped, resulting in a painful stab just below my knee. I quickly removed it and descended from the roof, reassured to find the bleeding ceased almost instantly. After carefully cleaning and bandaging the wound, I went about my day. However, after about two hours of activity, I noticed that the bandage was feeling unusually tight. Upon inspection, I discovered that the wound had been bleeding internally, causing a sizeable hematoma which began to grow significantly. I sought help from an EMT, concerned it might lead to compartment syndrome, and was advised to head to the emergency room. An X-ray confirmed extensive internal bleeding, with the hematoma nearly reaching the size of my knee. Fortunately, the wound eventually healed, albeit leaving a hard, immobile lump that felt like bone. Some months later, I accidentally fell on that area. To my surprise, the lump appeared to be smaller than before. A couple of weeks later, two identical lumps emerged overnight on every distal joint of my fingers. Just two weeks after that, the same phenomenon occurred on all ten toes. X-rays of my hands showed no abnormalities, leading me to consider the possibility of reactive arthritis, for which I have an appointment scheduled with a rheumatologist in September. Each time I discuss my knee lump with different doctors, they examine it briefly before expressing mild concern. This morning, I accidentally hit my leg against a drawer. An hour later, I squatted down and experienced familiar pain, noticing that the lump had shifted again—it was now smaller and seemed to have moved closer to my kneecap, rather than being located an inch below as it used to be. I am filled with questions regarding this unusual development. What exactly is this lump? Could it consist of metal fragments my body has surrounded? Is there a possibility of having it surgically removed? Moreover, could this lump be linked to the recent appearances of similar lumps on my fingers and toes? How can I seek further assistance if my primary care physicians dismiss these concerns?

It sounds like you've been through a challenging experience with your injury and the subsequent developments around the hematoma and new lumps. Let’s break down your concerns regarding the lump in your leg, its possible nature, and the recent occurrences of similar lumps on your fingers and toes.
Main Points:
- The lump in your leg is likely a residual hematoma or scar tissue from your injury.
- Shifts in the lump's size and position can occur and may indicate changes in the tissue or surrounding conditions.
- The new lumps on your fingers and toes might not be directly related to the leg lump but warrant evaluation.
Explanation:
-
Hematoma and Scar Tissue: After an injury, your body often reacts by forming a hematoma (blood collection outside of blood vessels) that can later become scar tissue. This can feel hard and immobile. Over time, this tissue can change as your body heals, which might explain the size and position changes you noticed, especially after impact.
-
Possible Metal Fragments: If there were metal fragments involved in the injury (from the tack remover), it's plausible for your body to surround them, creating a lump. However, this would typically require imaging studies to confirm.
-
New Lumps: The emergence of lumps on your fingers and toes may not be related to the hematoma but could indicate another condition like a form of arthritis or other inflammatory response. Reactive arthritis, which your rheumatologist will explore, could be one possibility.
Next Steps:
-
Symptom Monitoring: Keep track of the size and shape changes of the lump in your leg, along with any pain, swelling, or other symptoms in your fingers and toes.
-
Document Your Observations: Create a chart or log detailing when each lump appeared, their sizes, and any related activities (like bumping into objects). This information can be valuable for your upcoming rheumatology appointment.
-
Seek Clarification: If your primary care physicians dismiss your concerns, consider requesting a referral to a specialist like an orthopedic surgeon. They can assess whether surgical removal of the lump is appropriate and also investigate any potential metal fragments.
-
Follow Up on Rheumatology Appointment: Prepare specific questions for your rheumatologist about the connection between your leg condition and the new lumps. Inquire about the diagnostic process for reactive arthritis and any potential treatment options.
-
Impact Management: While waiting for appointments, manage any discomfort or swelling in the lump by applying ice or over-the-counter anti-inflammatory medications like ibuprofen, following dosing instructions.
Remember, it's crucial to advocate for your health. Don't hesitate to express any concerns you feel have been overlooked during your appointments. You're taking the right steps by seeking further assistance. Please let me know if you need more specific guidance or have further questions.

Concern Over Swollen Area on the Neck
To provide some background, I am a 35-year-old female in generally good health, aside from a well-managed autoimmune skin condition. I do not partake in smoking or alcohol consumption. Approximately one year ago, I sought medical advice due to difficulties with swallowing, during which I discovered a small lump situated on my neck, just beneath the chin and slightly right of my esophagus. After assessment, it was determined that my swallowing issues stemmed from gastrointestinal complications, which were promptly addressed. I underwent an ultrasound of my neck at that time, and the results were entirely normal. Although I never identified what the lump actually was, the clear ultrasound findings and my ability to swallow comfortably led me to leave it unmonitored. Now, this week, I've observed that the lump has become red, itchy, and noticeably larger. It resembles an insect bite and has an oval shape approximately the size of a quarter. I've scheduled an appointment with my general practitioner; however, the earliest I could get in is late next week. With pre-existing health anxiety, I find myself quite anxious, entertaining fears that this could be cancer, such as lymphoma. Could it be possible that the ultrasound failed to detect something significant? I am unsure about the capabilities of an ultrasound, but I distinctly recall pointing out the lump to the technician a year ago, and she made sure to examine that area thoroughly.
Experiencing Dizziness with Phone Use and Motion Sickness
At 22 years old, I stand at 5'8" and weigh 148 pounds. I’m currently prescribed venlafaxine and Paxil, which I have been taking together for several years to help manage my PTSD symptoms. My nutrition is well-rounded, and I typically engage in about an hour of walking daily. Stress levels are currently low due to a slow work pace, and I maintain a high water intake, seldom consuming alcohol or marijuana. Yesterday, I embarked on a brief car journey and unexpectedly started feeling nauseous, which is quite out of the ordinary for me. I attempted to check my navigation on my phone, and suddenly, my queasiness intensified. Once I returned home, I studied on my laptop without any issues, prepared meals, tidied up, and felt like everything had returned to normal. However, during my commute to work today, I again began to experience motion sickness. Since this morning, whenever I briefly use my phone, I’ve been hit with dizziness and a sensation of disconnection from reality. My phone interactions have been minimal—just opening Spotify to switch playlists and replying to a quick message from my boss. This whole situation has me puzzled, as I've never encountered such symptoms before.
Post-Operative Care After Parotidectomy
I'm unsure why I focused on the topic of showering, as this is more of a general inquiry about aftercare. My partner, a 35-year-old male who abstains from alcohol but uses cannabis, underwent a parotidectomy this past Tuesday, July 8th. I’m aware of the clear signs to monitor for (such as red streaks, fever, or foul-smelling discharge), but I could use some guidance on what swelling and redness is considered within normal limits, especially when not distinctly noticeable. He has been experiencing increasing swelling and redness. Applying ice has been challenging, leading to less icing than recommended. While the fluid draining from the area has been a clear pink, I've started to notice some yellowish discharge on the bandage when I change it. Moreover, even though the surgeon advised that he could replace the head wrap with a bandage, he prefers to continue using gauze pads for comfort. We are concerned about the adhesive on the bandage potentially tugging at his skin. Is there any specific reason to avoid using gauze and opting for a wrap instead? I have attempted to reach out to his doctor for clarification but have yet to receive a response. With the weekend nearing, I’m anxious to determine whether the situation indicates a risk of infection or if this is within the realm of normal healing. In case it’s relevant, he regularly takes oxcarbazepine, quetiapine (for psychiatric reasons and not sleep-related), hydroxyzine, and bupropion. Following his surgery, he was on hydrocodone/acetaminophen for pain but he just ran out this morning. Thank you so much for taking the time to read this and for any insights you can provide!
Concerning Fluctuations in Health Measurements
Age: 37, Weight: 45 kg, Height: 171 cm Former smoker; currently uses vaping devices. **Existing health issues:** - Osteoporosis - Hiatus hernia - Chronic neutropenia - Lymphopenia - Peripheral neuropathy **Current medications:** - Concerta 36 mg, taken twice daily - Lorazepam 1 mg, as needed (up to twice daily) Over the last two weeks, I've experienced a decline in my overall well-being, but I’ve been feeling unwell for about two years without any clear diagnosis. I haven't undergone any medical evaluations or routine check-ups in the last year. Recently, my Apple Watch has been recording abnormal data that I find concerning. I believe the condition I may be experiencing is referred to as tachy-brady syndrome, although I am not entirely sure. My respiratory rates have shown unusual fluctuations, something I have not encountered before. Notably, I've recorded three significant spikes in my readings: - June 28th, from 15:00 to 17:00: a shift from 25.5 bpm to 7.5 bpm - July 6th, from 05:00 to 12:00: a drop from 22.5 bpm to 8 bpm - July 9th, from 03:00 to 05:00: a change from 28 bpm to 8.5 bpm Additionally, my heart rate has followed a similar pattern, varying significantly and frequently throughout the day, often fluctuating from 40 or 50 bpm up to 110 or 130 bpm within the same hour. I have also noticed that my heart rate variability (HRV) sometimes dips into single digits, occasionally as low as 5 ms. For the past two years, I have battled with symptoms, including sudden jolts of breath followed by moments of hearing loss accompanied by ringing. There are stabbing pains in my legs, and my body often feels heavy. Fatigue has rendered me nearly bedbound over the past year, making it difficult to stand or move without feeling excessively tired. I also experience sharp, stitch-like chest pains that seem to come and go. In the last week, my appetite has diminished significantly, and I sometimes feel dizzy, whether I'm standing or lying down. I’m questioning the seriousness of these symptoms and whether they warrant concern, as my previous medical exams have not indicated any issues. It’s perplexing to consider whether I might be overreacting, or how reliable the data from my Apple Watch is. However, these readings are new for me, and they correlate with my worsening condition. I understand that anyone online can't provide medical advice and that consulting a healthcare professional is the best course of action. Yet, I’m left wondering just how troubling this situation is. After feeling unwell for such an extended time without a clear diagnosis, I feel lost on how to assess my health status effectively.
Eye Discomfort and Swelling Concerns
Greetings! I’m a 32-year-old male, and I've been experiencing noticeable swelling and discomfort around my eyes for several weeks. Initially, this issue started with pronounced dark circles under my right eye, which later progressed to swelling of the eyelid. Currently, I find myself dealing with painful bags beneath both eyes, which have become red, swollen, and consistently painful - almost like a stinging sensation that doesn’t let up. Interestingly, these episodes typically occur 2 to 3 times a year, but they usually affect just my right eye, presenting mainly as dark circles beneath it. It’s unusual for me to have eyelid swelling like this; normally, it lasts only a few days. For context, I haven’t consumed any alcohol or tobacco since New Year’s Eve, which was seven months ago. I had been a moderate user of both since I was 19. I also used to take allergy medication for many years but stopped that around six months ago, and I've been fine ever since. The same goes for my acid reflux medication; I ceased taking it without any noticeable issues afterward. Currently, I only have a prescription for 20mg Adderall XR, which I take daily. I visited urgent care, where the doctor suspected dermatitis or eczema. I was given hydrocortisone cream to apply cautiously to the affected areas. While it provided temporary relief, the problem persists and remains quite severe. To add to my situation, my sleep is lacking – I typically manage only 4 to 5 hours each night, and I feel overwhelmed with my numerous responsibilities. I would greatly appreciate any advice or insights regarding my condition. Thank you in advance for your assistance! I have shared some images in the comments for reference.
