Do Cysts Typically Persist?
As a 16-year-old female, I discovered a small, firm, inflamed bump in my armpit roughly two years ago, following a shaving session. Eventually, I noticed that there appeared to be a small head on the bump, similar to a pimple that occasionally released some pus. After that initial observation, I tended to overlook it. Upon revisiting the area recently, I found that although the inflammation has subsided, the bump remains present, and the previously noticeable head seems absent, leaving only a minor indention in the skin. Is it common for cysts, possibly resulting from an ingrown hair, to linger without disappearing?

Cysts, especially those resulting from ingrown hairs or blocked follicles, can persist for a long time and may not disappear on their own. It’s not unusual for these bumps to remain firm and visible, even after inflammation has decreased.
Explanation
The bump you’re describing could likely be a sebaceous cyst or an inflamed hair follicle. These types of cysts can develop when hair follicles are blocked, and they may continue to be present or change in appearance over time. While they can sometimes resolve spontaneously, many remain without causing further issues.
As a 16-year-old, your skin is still developing, which can contribute to the persistence of such conditions. Even if the bump has reduced in inflammation and the pus is no longer being expelled, the cyst itself might remain present.
Next Steps
-
Monitor the Cyst: Keep an eye on the bump for any changes in size, color, or symptoms (like pain or fever). If it remains stable, that may be a good sign.
-
Avoid Irritation: Try not to shave or irritate the area further, as this can exacerbate inflammation or lead to new cyst formation.
-
Warm Compress: Apply a warm, damp cloth to the area for 10-15 minutes a few times a day. This can encourage drainage if it becomes inflamed again and soothe any discomfort.
-
Hygiene: Maintain good hygiene of the area to prevent infection—a gentle cleanser is usually sufficient.
-
Consider Observation: If the cyst does not improve, worsens, or if you notice any new symptoms, consider seeking advice from a healthcare professional to discuss possible treatment options.
You are doing well by observing the changes in your skin, and it’s important to prioritize your concerns while monitoring the situation. Let me know if you have more questions or need further information!

Seeking Guidance Following Ultrasound and Blood Test Results
A 25-year-old Caucasian woman, approximately 5 feet 3 inches tall (potentially 1 to 2 inches shorter), weighing 92 pounds, has a medical history free of medications, drugs, or alcohol consumption. On June 3rd, she sought urgent care to address persistent discomfort located in her upper right abdomen. The sensation is described as a mild sharp pain that intensifies when lying down—particularly during sleep—and also when she experiences the urge to urinate. Although the pain does not significantly interfere with her daily activities, it appears on almost a daily basis. Additionally, she experiences excessive thirst, leading to increased water consumption, a detail she inadvertently omitted during her visit. These symptoms have been present for approximately two months. The healthcare provider referred her for both a blood test and an abdominal ultrasound, which was conducted on July 10th, with the blood test performed the same day as her urgent care visit. The blood work showed no significant abnormalities, except for a few noteworthy results: - **Basic Metabolic Panel**: - Urea Nitrogen (BUN): Low at 6 mg/dL - **IGE/Food Allergy Panel**: - Immunoglobulin E: Elevated at 247 kU/L (possibly linked to seasonal allergies) - Wheat IGE: High at 0.12 kU/L (no reported allergy to wheat) Prior to the ultrasound, she refrained from eating for 16 hours and limited water intake to only 2 small sips 6 hours before the test. The findings from the ultrasound are as follows: **FINDINGS:** - **Liver**: Appears normal, measuring 14.3 cm. The main portal vein has a diameter of 0.7 cm, with appropriate hepatopetal flow. The middle hepatic vein is patent, and there are no masses or cysts within the liver. - **Bile Ducts**: No dilation present in either intrahepatic or extrahepatic bile ducts, and the common bile duct measures 3.7 mm. - **Gallbladder**: Normal appearance with no stones, wall thickening, or fluid accumulation. - **Pancreas**: Portions observed are unremarkable, though evaluation is partially hindered by bowel gas. - **Right Kidney**: Measures 9.9 cm with no signs of pelvicaliceal dilatation; parenchymal thickness and echogenicity are normal. A structure at the upper pole measures 2.2 x 2.1 x 1.6 cm, raising the question of whether it is a cyst or mass. - **Inferior Vena Cava**: Appears normal in the visualized segment. **IMPRESSION:** 1. The presence of a potential mass or cyst at the upper pole of the right kidney warrants further evaluation via a CT urogram with and without contrast. 2. Findings from the remainder of the ultrasound of the right upper quadrant are unremarkable. She accessed these results through online patient portals and has yet to receive any communication—either calls or messages regarding her findings. Therefore, she is uncertain whether to contact urgent care or the imaging center regarding the suggested CT urogram and seeks clarity on what these results may indicate regarding her health condition.
Seeking Guidance on Ongoing Health Issues
I'm a 19-year-old female living in the UK, and I've been facing a series of health challenges this year that have left me feeling quite miserable. After battling tonsillitis six times within four months, each treated with penicillin, my well-being has taken a downturn. Over the past month, I have been experiencing intense, pulsing pain throughout all my joints. Even after a day of minimal activity, I wake up feeling as if I’ve just completed a strenuous 12-hour hike. My muscles and joints are constantly sore and rigid, making me feel unusually lethargic for my age. Despite sleeping around 8 to 9 hours each night, I find myself needing at least an hour of napping during the day. By 11 PM, I can hardly keep my eyes open, even if I've spent my day resting. This fatigue has impacted my ability to join family outings, and it’s disheartening to see my 60-year-old mother able to do far more than me. Additionally, I've been grappling with severe nausea and episodes of vomiting, particularly when I feel anxious, like when I’m catching a train. Sometimes my abdomen swells dramatically, making me look almost as if I’m nine months pregnant. After eating, I also experience debilitating pain in my stomach. My bowel habits are extremely unpredictable; I can go an entire week without a bowel movement or face a week of diarrhea. I initially thought that my gut flora might be disrupted due to the antibiotics, so I've tried incorporating various foods to promote gut health, but my symptoms appear to be deteriorating instead. Moreover, I have been dealing with a recurring rash for the last couple of years, which causes intense itching on my forearms and chest. The affected areas become quite warm and tiny red spots appear under my skin, though it doesn't resemble hives. A few years back, I consulted a doctor about this issue, but they couldn't provide an explanation. I'm starting to wonder if it might be an allergy of some sort. Lastly, I have suspicions of endometriosis, which adds another layer of difficulty to my situation. I do have an appointment scheduled with my doctor in a few weeks, but I am hoping for some advice on what questions I should pose during the visit, especially given my lengthy list of symptoms. Any insights would be greatly appreciated!
Concern Over Temporary Bruise on My 3-Month-Old
Hello everyone! I wanted to share an experience with my 3-month-old daughter. Recently, while my dad was holding her right after they had been in the pool, I observed a mark on her skin that looked like a bruise. It appeared quite dark initially but then faded away within a few minutes. In addition, she seems to be more irritable over the past couple of days. However, I suspect this might be due to a nursing strike, as she's been able to take a bottle with pumped milk without any issues. She’s sleeping normally, displaying no signs of lethargy, but her fussiness has noticeably increased. Should I be worried about this bruise-like mark, especially since it seemed to vanish so quickly?
Seeking Insights on Lymph Node Swelling
I’m a 17-year-old female (5'1", 135 lbs) and I’ve noticed several swollen lymph nodes on my neck—approximately 4 to 5 in total. These nodes seemed to manifest during a period of illness and have persisted ever since. The first one made its appearance a few years back, while the other nodes emerged over the last couple of years amid various health issues I encountered. The swollen nodes tend to become painful when I poke at them, but I haven't experienced any other symptoms alongside this issue. Additionally, I deal with a condition known as strabismus, where my eye turns inward. I did visit a hospital regarding this, and they confirmed that there were no cancerous signs in the vicinity of my eye, a condition I’ve lived with for about 6 years now. I struggle with health anxiety, which has led to a significant fear of consulting healthcare professionals. Therefore, I decided to reach out here first to see if anyone else has faced a similar situation or has any advice.
