Could It Be MRSA or Just Bug Bites?
About three weeks ago, I noticed a bothersome, itchy bump on my foot. At first, I suspected it might have been caused by a spider bite, especially since I live in an area where brown recluses are common. A week later, my staph infection, which has previously affected my nose, flared up, prompting my doctor to prescribe neomycin to apply twice daily in each nostril. Unfortunately, I'm unable to use mupirocin due to a severe reaction I experienced with it. Last Thursday, I developed what I initially thought were insect bites on my upper arm, upper thigh, area around my right clavicle, and the left side of my abdomen. The itching is incredibly intense, and these spots feature a prominent hole in the center that emits a slight clear yellow fluid. The level of itching is driving me to distraction. I'm concerned that I might have transferred staph bacteria from my nose to my skin or that these could be spider bites. I even considered the possibility of bed bugs, despite never having encountered them before. I searched thoroughly through my bed, dismantling it entirely, while also checking the baseboards, light sockets, curtains, and nightstands. I didn’t find any signs of bugs, droppings, or casings. As for that initial bump on my foot from three weeks back, there’s still uncertainty whether it was indeed the result of a spider bite or something else altogether.

It sounds like you’re dealing with an uncomfortable and frustrating skin condition, and your concerns about staph infection or insect bites are completely valid. Let’s break this down to prioritize what you might want to do next.
Main Points:
- You could be experiencing a skin infection or an allergic reaction rather than just insect bites.
- The presence of itching and fluid suggests that this may need more focused care.
- Monitoring your symptoms closely and taking specific self-care steps can help in the meantime.
Explanation:
Given your history of staph infections and your recent symptoms, it’s possible that what you’re seeing is related to your previous infection or an inflammatory response to an allergen (such as insect bites or other irritants). The itchy bumps with a central hole and discharge can indicate a skin infection, potentially exacerbated by the staph bacteria or another irritant present.
Considering your concern about transferring bacteria from your nose, any breaks in the skin (like those from scratching) can allow bacteria to enter, which may cause these symptoms.
Next Steps:
-
Keep the Areas Clean: Gently clean the affected areas with mild soap and water to reduce the risk of infection.
-
Avoid Scratching: Though the itching is intense, try to minimize scratching to prevent further skin damage and spread of bacteria.
-
Apply a Cool Compress: To relieve itching, you might find it helpful to apply a cool, damp cloth to the itchy areas several times a day.
-
Over-the-Counter Remedies: Consider using an over-the-counter antihistamine (like cetirizine or loratadine) to help with itching, but be sure to follow the dosage instructions.
-
Monitor for Changes: Keep an eye on your symptoms over the next few days. Look for changes in size, color, or fluid from the bumps. If they worsen, become more widespread, or if you develop new symptoms (such as fever), this would be a concern.
-
Document Your Symptoms: Consider keeping a diary of when the bumps appear and any other symptoms you notice, which could help identify triggers or patterns.
If the condition does not improve or continues to get worse, seeking medical advice would likely be necessary, as you may need a more targeted treatment for a potential infection or another dermatological concern. This proactive approach can help you manage your discomfort while also ensuring you’re monitoring for anything serious.

What Happened After My Wart Treatment?
A 32-year-old man here, managing pre-diabetes effectively. I had been dealing with a plantar wart on my toe for several years. A few months back, I sought treatment from a podiatrist since it began causing discomfort. The doctor scraped it and applied a potent medication to eliminate it, assuring me that it was completely removed after two sessions. Initially, everything appeared to be healing well, with a clear indentation where the wart had been. However, after a few more months, the area has become exceptionally hard and surprisingly painful, growing larger than before. I'm planning to revisit the doctor soon but I'm uncertain whether it's just an accumulation of tough skin that I might be able to file down for relief, or if there's a different issue at play.
Addressing Worsening Bilateral Intersection Syndrome: A Personal Account
Hello everyone. I’m a 31-year-old male, standing at 5 feet 5 inches and weighing 77 kilograms. My medical history includes over a year of intravenous stimulant use, specifically with substances like Mephedrone and Methamphetamine; however, I have been clean for the past month and a half. Currently, I’m self-administering testosterone at a dosage of 100mg weekly and plan to discontinue it this September. I have no history of alcohol consumption or smoking. The symptoms began eight months ago in my right wrist and have just started affecting my left wrist within the last month. Initially, I was diagnosed with De Quervain’s Tenosynovitis. To manage my condition, I utilize a splint during the night and take ibuprofen every four to six hours. Additionally, I apply ice to the affected area and use a cold gel for further relief. I have also attended occupational therapy sessions and closely adhered to their recommendations. Despite these efforts, my hand function appears to be deteriorating daily; my movements are often accompanied by a locking and popping sensation. Pronation is particularly excruciating compared to supination. Finkelstein’s test yields a positive result, but the associated pain is only around a 2 or 3. In contrast, the discomfort from the locking and popping at the intersection escalates to an 8 on the pain scale. As a lifelong PC gamer, I haven’t experienced any prior issues like repetitive strain injury (RSI) or carpal tunnel syndrome. The onset of these symptoms correlates with a period when my substance use affected my gym routine, leading me to take a break for two to three months. Strangely, the discomfort first manifested in my right arm and has since progressed to my left arm. There is a family history of lupus, and while I underwent blood testing, the doctors have advised a retest, leaving me without a definitive diagnosis so far. I am wondering if there may be a connection to the lupus in my family, or if the hiatus from the gym could have led to my tendons becoming scarred and stiff. Should I consider advocating for an ultrasound? I had an X-ray when I was diagnosed with De Quervain’s, but the results warranted no further action. Currently, I don’t experience joint or tendon pain in any other areas. In the past, I occasionally dealt with issues such as elbow pain from weightlifting, tennis, or golf overtraining—but nothing has surfaced elsewhere since this began.
Considerations on Witzel G-Tube Placement
I am currently dealing with intestinal failure and chronic intestinal pseudo obstruction while I await a modified multivisceral transplant. My surgeon has recommended replacing my existing G-tube, which was placed using the Stamm technique, with one that utilizes the Witzel method. The issue stems from the significant dilation and fragility of my stomach, which is a result of its failure, leaving me questioning the potential success of this procedure. I've been informed that this is a rare intervention, and despite my efforts to find more information online, I’ve encountered only a handful of articles that don’t provide the detailed answers I need.
White Patch Near Tonsils: Persistent Sore Throat Concerns
I am a 45-year-old male, standing 5 feet 9 inches tall and weighing 140 pounds. My health has been complicated by significant gut dysbiosis and a very limited diet. For the past three weeks, I've experienced a persistent sore throat primarily located where the nasal airflow from my left nostril meets my throat at the back. This discomfort feels akin to the initial stages of a cold, characterized by a stinging and itchy sensation. However, it has lingered for an unusually long time. This issue coincides with an incident three weeks ago when professionals from Servpro treated our basement due to a water backup from a broken pipe linked to our septic system. During their cleaning process, I found it impossible to stay in the house, even with the cellar door shut, as the chemicals they deployed induced a similar scratchy sensation in my throat accompanied by uncontrollable sneezing. Additionally, they vented some of their wastewater adjacent to my bedroom window, which I have kept closed since discovering that. Although my sore throat has somewhat improved, it remains a concern. Today, I noticed a white patch in the area positioned in front of my tonsils, in a space just behind the flap that precedes them when viewed from the mouth's front. There is also a smaller round lump that resembles a fluid-filled sac. I’m uncertain about the normalcy of these findings and have scheduled an appointment with my dentist for this Friday. I also intend to reach out to my primary care physician tomorrow, although I may face delays in securing an appointment. One of my primary worries is whether I have sustained chemical burns resulting from an allergic reaction to the cleaning agents used, but I am also aware that other factors could be at play here. I would highly appreciate any insights on this matter. Thank you!
Should I Rush or Take My Time? - Insights on Thyroid Cancer Treatment
Patient Overview: 36-year-old female with a thyroid nodule measured at 4.8cm located on the right lobe, classified as substernal. - TI-RADS classification: 3 - Bethesda classification: III - Genetic findings: HRAS:p.Q61R c.182A>G - Negative results for Medullary Thyroid Carcinoma (MTC), parathyroid neoplasia, and BRAF. - No detection of RET/PTC1 or RET/PTC3 mutations. - Afirma test indicates a 75% risk of malignancy. Patient experiences mild swallowing difficulties. (Note: A small nodule on the upper lobe of the lung was identified during a CT scan, which may be relevant.) I have a neutral stance on my Ear, Nose, and Throat (ENT) specialist. I consulted with her once for a brief examination, after which she recommended a fine needle aspiration (FNA). The core issue I’m facing is that this specialist works in a hospital where I've previously encountered two very unsatisfactory experiences, although these incidents were limited to the Emergency Room and did not involve surgical procedures. Alternatively, there is another hospital known for its positive reputation (Houston Methodist) where I’ve found a surgeon with a strong standing in his specialty based on my limited research. However, scheduling an initial consultation there would delay my care, potentially until around July 9 at the earliest. My dilemma is whether to proceed quickly with treatment, even if it means going to a less favorable hospital with an acceptable physician, or to wait for a more reputable facility with a higher caliber surgeon. I find myself torn between these options and would greatly appreciate advice from someone experienced regarding the seriousness and intricacy of my situation. Thank you in advance for your guidance.
