Unusual Swelling on Skin: Need Advice?
Age 27, weighing around 130 lbs, I have a history of low immunoglobulin G (IgG) and A (IgA), as well as a past of protein-calorie malnutrition. I am diagnosed with Autism Spectrum Disorder (ASD) and take Effexor along with gabapentin; I also use recreational cannabis. This morning, I woke up to discover a swollen bump on my skin that is somewhat tender. I suspect I might have been picking at it unconsciously, but I’m uncertain. I do have a tendency towards skin picking as a result of my ASD and OCD, although I maintain diligent skincare and hygiene practices. Regardless, I am concerned that it may be infected. My mother has experienced precancerous lesions, and there is a history of pancreatic cancer on my father’s side. As for my dad, I'm not certain if he has any skin cancer, but he believes that cancer is contracted from doctors. He works outdoors and is skeptical about sunscreen, which raises some concerns. Should I seek a consultation at a clinic, or is it manageable with home care?

It’s understandable to feel concerned about an unusual swollen bump on your skin, especially given your medical history and family background. Here's a breakdown of the situation:
Main Points:
- The swelling could be related to skin picking or an irritation, but there's a possibility of infection.
- Given your history of low immunoglobulin levels, it's important to be cautious.
- Monitoring for specific signs will help determine the best course of action.
Explanation:
The swollen bump may be caused by several factors: skin picking, minor trauma, an allergic reaction, or even an infection. With your history of low IgG and IgA, your immune system might not respond as robustly to infections, making it crucial to keep an eye on this situation. Concerns about family history of skin issues and cancer are valid, and while this swelling may not necessarily be cancerous, it’s wise to be vigilant.
Next Steps:
- Monitor Symptoms: Keep an eye on the bump for any changes—look for increased redness, warmth, pus, or a fever, all signs that it may be infected.
- Avoid Picking: Resist the urge to pick at it. Consider using a soft bandage to protect the area from further irritation.
- Apply a Clean Dressing: Keep the area clean and potentially apply a sterile bandage. If you suspect it might be infected, consider using an over-the-counter antibiotic ointment like Neosporin.
- Hydrate and Nourish: Ensure you are drinking plenty of water and eating a balanced diet rich in nutrients to support your skin and overall health.
- Practice Hygiene: Continue your diligent skincare and hygiene routines, as these can help prevent further issues.
- Document Changes: If the bump does not improve or worsens over the next few days, document these changes (like size, color, tenderness, etc.) to discuss in your next healthcare consultation.
If you observe severe symptoms such as significant pain, worsening swelling, fever, or pus, or if you continue to have concerns, consider seeking medical advice sooner. Being proactive with skin changes is important, especially with your medical history.

Could I Have Been Poisoned? Here's What Happened
A couple of days ago, I was staying in a hostel in France. Over three days, I had been enjoying a bottle of rosé wine, taking it slowly, glass by glass. On a Wednesday afternoon, I was set up in the hostel's common area, working on my laptop while sipping on my wine. The space had dining tables and chairs available for guests. Across from me sat another woman, with whom I exchanged polite greetings; our interaction remained at a casual level. Suddenly, the charismatic hostel manager entered the common area. As it was my final night in the city, I took the initiative to approach him and invited him for a drink after his shift. To my delight, he agreed, and we arranged to meet outside the hostel around 7 PM. Following that, I returned to my spot at the table. Not long after I sat down, the woman across from me asked if I knew him prior to this encounter. I explained that we had just met, to which she responded with a comment about his attractiveness. This led our conversation into topics such as travel, languages, and romance. At one point, I excused myself to use the restroom. Trusting the surroundings, I left my purse, laptop, and nearly full glass of wine on the table, believing I would be back quickly. When I returned, she was still there, and my belongings appeared untouched. The clock had just passed seven, so I gathered my items, finished the last sip of wine, and prepared to head out to meet the manager. Coincidentally, she also made her exit from the common area at the same time. As I walked to the restaurant with the manager, a sudden, intense headache hit me. I initially thought it was due to hunger. Upon arriving at the restaurant, I started experiencing additional symptoms. While attempting to engage with the attractive guy, I battled a headache, nausea, blurred vision, and a racing heart. I suddenly felt warm, and a wave of nausea washed over me. He ordered a beer, and I settled for a sparkling water with lemon. I informed him I wasn’t feeling well, attributing it to possible hunger. I whispered a quick prayer, anxious about the prospect of being ill in a foreign place, especially since I had a bus to catch later that night—visiting the hospital felt like it would be a hassle. After downing a pint of water and devouring a generous amount of Creole rice and stew over the next couple of hours, I noticed some improvement, though my stomach still felt off. As the evening progressed, I continued to feel better, even enjoying some drinks and sharing a kiss with the guy, which led me to dismiss my earlier discomfort. Despite that, a nagging feeling remains that the woman I had spoken with might have interfered with my wine. I wish to believe otherwise, but we exchanged Instagram details during our chat, and now I can’t find her account; it seems she has blocked me entirely. Now I’m feeling mostly okay, save for a bit of a lingering uneasy sensation in my stomach. But I’m left with questions: Could I have been poisoned? If so, with what substance might that have occurred? Is it necessary for me to see a doctor considering this incident took place two nights ago? Given that I wasn’t very ill and I’m now in a different country, I wonder if my symptoms could potentially stem from severe hunger and dehydration rather than anything more sinister. I feel uncertain and don’t know how to proceed. My priority is to ensure that whatever caused this does not have any lasting effects on my health.
Experiencing Issues with My Voice: Who Should I Consult?
Greetings! I'm a 24-year-old male with an ordinary build, perhaps a bit lighter than average. For quite some time, I've been told that I speak quite softly, and people often struggle to hear me, particularly in crowd settings. I'm uncertain whether this is simply a reflection of my personality or social discomfort, or if there's an underlying medical concern. I've observed that my voice often unexpectedly "drops out" during conversations, creating moments where I sound nearly like I'm whispering, though that's not my intention. Some days, speaking can become particularly draining, and it seems my voice falters more frequently, making it feel as though a different voice is coming from me due to the significant alterations in tone. This issue also manifests when I attempt to sing; there are notes where I can only produce a high-pitched, airy sound without any real vocalization. Could these symptoms indicate a long-ignored issue that I should address, or are they considered commonplace?
Unexpected Swelling in the Genital Area
Greetings, I’m a 17-year-old male, and recently I observed an unusual swelling around the shaft of my penis, specifically in the area that contacts my hand during masturbation. Naturally, this doesn’t seem right, and I’m quite anxious about it. I suspect it might be a reaction to excessive stimulation earlier today, but I’m not entirely sure. I appreciate any guidance you can offer. Just to note, I’m posting this on a temporary account to maintain my privacy.
Navigating the Challenges of a Manipulative Supervisor
Hello everyone, I'm currently experiencing a challenging situation at work and would greatly appreciate any insights or words of encouragement from those who can relate. My supervisor exhibits toxic behaviors and is highly manipulative. She tends to imitate my personality and concepts, presenting them as if they originated from her. While she plays the innocent and naïve role in front of others, she consistently undermines me behind the curtains. Moreover, she attempts to exert control over my social interactions. For instance, she reacts with jealousy whenever I engage with male coworkers or forge new friendships. She interrupts conversations and even spreads false narratives about me. She seems to have adopted a maternal-like demeanor, frequently “guiding” me in a condescending manner, but her interference distracts me from my actual objectives, such as preparing for exams or considering a career change, leaving me feeling inadequate. Additionally, her physical boundaries are invasive; she touches me in ways that are uncomfortable, and she keeps tabs on me and my friends through social media. She seems to create rifts between me and my peers, leaving me feeling emotionally and mentally drained. I also resonate with the idea of the “evil eye” and have observed peculiar occurrences since I confided in her about my life. As an introvert (INTJ), I struggle to connect with my colleagues, and her public ridicule regarding my attempts at socializing only compounds this difficulty. I am seeking advice on several matters: - What strategies can I employ to establish boundaries with a manipulative superior who holds power in the workplace? - How can I safeguard my emotional, mental, and spiritual well-being while remaining employed here? - Have any of you encountered a similar scenario with a toxic manager? What methods were effective for you? - Any suggestions for managing disingenuous friendships and the issue of identity theft in the workplace? Thank you for taking the time to read my post. I truly value any support or guidance you can offer. **Summary:** My supervisor emulates my personality and ideas, controls my social interactions, invades my personal space, and pretends to be a supportive friend while consistently undermining me. I'm finding it difficult to set boundaries due to her authority over me. I'm looking for advice on managing toxic supervisors, shielding myself emotionally and spiritually, and navigating fake friendships and jealousy in the work environment.
