Should I Be Worried? Firm Lump on Thigh with Expanding Swelling
I’m seeking guidance regarding a concerning issue. A solid lump emerged on my inner thigh just two days ago and has enlarged to about a centimeter in size within the day. It seems as if there are two adjacent abscesses. While it isn’t painful, I noticed some swelling yesterday, which has since increased. I am a 25-year-old trans man, standing at 5'10" and weighing around 170 lbs. I have a history of skin infections, including multiple occurrences of cellulitis and shingles that I experienced when I was 11. Additionally, I sometimes get pimples on my inner thighs. Currently, I receive 0.5mL testosterone injections weekly and take 200mg of sertraline daily. I have also recently begun iron supplements.

It's understandable to be concerned about a firm lump with accompanying swelling on your thigh, especially given your history of skin infections. While there are several possible causes for this lump, including cysts, lipomas, or even an infection like an abscess, it's essential to take note of your symptoms and their progression.
Explanation
A solid lump that expands can sometimes be a benign growth, such as a sebaceous cyst or lipoma. However, given your previous experiences with skin issues and infections, it's also important to consider the possibility of an infection, especially if there's swelling involved. In this case, the lymphatic response might create an area of swelling around the lump, which can be concerning.
Next Steps
-
Monitor the Lump: Keep an eye on the lump's size, texture, and any new symptoms that may develop (e.g., redness, warmth, pain, or pus). If it continues to grow or changes significantly, this would be a key indicator that further evaluation is needed.
-
Self-Care Measures:
- Keep the Area Clean: Gently wash the area with soap and water to prevent any potential infection.
- Avoid Irritation: Wear loose-fitting clothing to minimize friction on the lump.
- Warm Compress: Apply a warm compress for 10 to 15 minutes several times a day to promote drainage if it seems to be an abscess.
-
Document Symptoms: Keep a diary of any changes in the lump, including size, any new symptoms, and overall skin condition. This information could be useful if you need to seek further assessment.
-
Watch for Red Flags: If you develop symptoms such as significant pain, fever, drainage of pus, or if the swelling rapidly worsens, this may indicate a need for immediate attention.
By carefully monitoring the lump and taking appropriate self-care steps, you can make an informed decision about whether further evaluation is necessary. Ensure you pay attention to any changes and prioritize seeking help if you have any concerning symptoms or if the situation worsens.

Visual Disturbances: Seeking Guidance
Overview: I’ve been experiencing some ongoing visual disturbances that have prompted me to seek advice. To provide some background, I am a 21-year-old white male in the United States, standing at 5 feet 8 inches and weighing slightly over 170 pounds (though I’m not sure about the precise figure, I know it’s no more than 180). For about seven years, I neglected the need for corrective lenses and found myself spending excessive time in front of screens. Given these circumstances, I’m wondering whether I should consult an optometrist, an ophthalmologist, or my general practitioner. What could be the potential causes of these symptoms? They have persisted for quite a while, possibly even years.
Prolonged Exposure to Magnets: A Query about Safety
Hello everyone, I’m a 26-year-old male and I have a question regarding my work habits. I habitually carried a magnet attached to my hard hat to pick up metal shavings and manage wiring diagrams. Given that these magnets are positioned close to my head, I’m wondering about the safety implications. Are there any research findings related to long-term exposure and potential harm? I can't help but notice that when I carried the magnets, I experienced more intense headaches, though it coincided with the hot summer months, leading me to think dehydration might have played a role. I also do not have any medical implants or serious injuries, apart from a previously torn ACL. I'm intrigued about the matter, particularly since my current magnets are quite weak, and I'm considering upgrading to more powerful ones.
Struggling to Increase My Weight
At 5 feet 7 inches tall and weighing 130 pounds, I’m a 17-year-old male who has been grappling with weight gain for the past year and a half. Despite my efforts, I’ve only managed to add 10 pounds during that time. My daily caloric intake sits between 1,500 to 2,000 calories, yet I find it challenging to consume more than that without feeling nauseous. I work out regularly, hitting the gym approximately three to four times each week, and I also engage in a lot of basketball. Despite my dedication, I feel like my strategies for gaining weight simply aren't effective. What would be the most straightforward and quickest way for me to pack on some extra pounds?
Should I Be Concerned?
Greetings everyone. I’m a 22-year-old woman seeking some guidance. For as long as I can recall, I have noticed these "lumps" on my scalp. They generally match my skin tone and appear stable, showing no signs of growth or change in size. Their height ranges from approximately 1/32 to 1/16 of an inch, if measured generously. I’m curious to know if these should raise any red flags for me. Thank you for your input!
Inquiry About Childhood Chiropractic Experience
Hello Reddit! I’m reaching out to seek insights regarding an experience from my adolescent years, roughly between the ages of 12 and 14. I’m currently 25 years old (female). To give you a bit of context, I encountered a troubling incident while bending down to access my locker; suddenly, my neck locked in a position to the side, rendering it completely immobile. The pain was unbearable. In response, my father thought it best to take me to a chiropractor, which seemed to provide some relief, yet I continued to endure significant pain and noticed an unusual odor that lingered for nearly a week. Unfortunately, this episode recurred a few months later, and I underwent the same routine; once again, I experienced that odd smell and extreme discomfort. Since those two occurrences, I have faced similar issues on only a couple of occasions, during which I opted for hospital care instead of chiropractic treatment. The medical professionals provided muscle relaxants, which effectively alleviated my pain without any bizarre lingering odor. Since those formative experiences, I have been left with a constant discomfort in my right shoulder, which feels strained frequently, and I find that my head tends to tilt towards one side. What could have caused this neck locking issue during my youth, and could my decision to visit a chiropractor instead of a physician have led to ongoing complications? I'm eager to understand what happened during those situations!
