Understanding the Distinction Between a Boil and Sebaceous or Subcutaneous Cysts
Male, around 45 years old, weighing 160 lbs. White, a smoker, and drinks socially. Generally speaking, I maintain good health with a standard level of physical activity suitable for my age and weight. Since my teenage years, I’ve experienced occasional large bumps that resemble painful pimples but never form a proper head. These bumps tend to be swollen and sensitive, particularly when any pressure is applied. During my adolescence, these uncomfortable eruptions primarily appeared on my face. I often resorted to using a needle to puncture them, aiming to extract what I assumed was the source of the problem, which would result in a discharge of pus, plasma, and sometimes blood. After clearing everything out, they would typically resolve, although they occasionally returned and sometimes left a scar. This was back in the 1990s when my family couldn't afford medical consultations. Over the past 25 years, I've continued to experience these bumps sporadically, but recently, in the last 3-4 months, I’ve encountered a similar issue on my buttocks (this isn't the first occurrence). I attempted to manage it in a comparable manner, but my efforts to puncture it and make it drain were unsuccessful, partly due to the difficult location. I’ve used a triple-antibiotic ointment both when I tried to pop it and when I left it alone. Eventually, it has shrunk but has reappeared at least three times over the last four months and is presently enlarging again. Consequently, I decided to do some research. According to several medical sources I found online, my symptoms align more with that of a boil rather than what I had always understood to be a sebaceous or subcutaneous cyst (though I’m unsure of how to differentiate between these two types of cysts). So, what am I dealing with — a boil or cyst? What home care methods can I attempt to alleviate this issue? At what stage should I seek a doctor’s advice? If I do decide to consult a healthcare professional, what procedures can I expect? Lastly, for clarity now and in the future, what are the key differences between a boil (assuming that's the right identification) and sebaceous or subcutaneous cysts?

It sounds like you've been dealing with persistent skin bumps for many years, and your recent experience has prompted some understandable concern and curiosity about what they are and how to manage them. Let’s clarify your situation and discuss your options moving forward.
Key Differences Between Boils and Cysts
-
Boils (Furuncles):
- Cause: Usually caused by bacterial infection (most commonly Staphylococcus aureus).
- Appearance: Red, swollen, and painful lumps that may develop a white or yellow center. They often ooze pus when they burst.
- Symptoms: Tenderness, warmth, and sometimes fever or systemic symptoms if infected.
- Location: Can appear anywhere on the body, including areas subjected to friction.
-
Cysts (Sebaceous or Subcutaneous):
- Cause: Often formed from blocked sebaceous glands or hair follicles.
- Appearance: Generally slow-growing, round lumps that are not usually painful unless inflamed.
- Symptoms: May be asymptomatic, although inflammation can lead to discomfort.
- Location: Commonly found on the face, neck, scalp, and torso.
What You Might Be Experiencing
Based on your description, especially noting pus production and pain, it sounds like you may be dealing with boils. They can recur in the same area, especially in sites of friction.
Next Steps for Home Care
- Warm Compresses: Apply a warm, moist cloth to the area for 20 minutes, several times a day. This can help soothe the area and may promote drainage if it's a boil.
- Keep it Clean: Wash the area gently with antibacterial soap, and avoid picking or squeezing the bump to prevent further irritation or infection.
- Antibiotic Ointment: Continue using the triple-antibiotic ointment after cleaning the area.
- Pain Management: Over-the-counter pain medications, like ibuprofen or acetaminophen, can help manage pain and inflammation.
When to Seek Medical Attention
- If the bump becomes increasingly painful, larger, or shows signs of spreading redness.
- If you experience fever, chills, or other systemic symptoms.
- If the bump does not improve within a week of home treatment or worsens.
- If you have multiple recurring boils, as this may indicate an underlying issue like a skin infection or other health concerns.
What to Expect from a Healthcare Professional
If you consult a doctor, they may:
- Conduct a physical examination to assess the bump.
- Take a sample of the pus for culture if an infection is suspected.
- Drain the boil (if it is large or persistent), which can help alleviate pain and expedite healing.
- Prescribe antibiotics if a bacterial infection is confirmed.
Conclusion
By following the suggested home care steps and closely monitoring your symptoms, you can manage the discomfort effectively while being prepared to seek further medical advice if necessary. Understanding the distinction between boils and cysts can help you recognize and address these skin issues in the future. If you have any more specific concerns or questions, feel free to ask!

Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
Seeking Insights: My Journey with Undiagnosed Neurological Symptoms
Hello everyone, I'm a 34-year-old female grappling with neurological symptoms that first appeared in October, and I’m eager to hear from anyone who might have faced similar challenges. My journey began with unexpected migraines, blurred vision, and an ongoing sensation of being off-balance or intoxicated. Gradually, I began experiencing mainly sensory-related symptoms, such as tingling and burning sensations, feelings of extreme heat and cold, sharp pains radiating in my arms and back, as well as discomfort in my hands and toes, alongside intermittent numbness. I also endure varying degrees of weakness and heaviness in my right side, specifically my arm and leg, although I haven’t suffered complete functional loss. The nature of my symptoms is erratic; they fluctuate rather than consistently deteriorate. An MRI revealed mild, scattered lesions in the white matter, which were deemed nonspecific. Further tests from a lumbar puncture returned normal results, showing no markers of inflammation, and the oligoclonal bands were not present. A thorough range of lab tests yielded no significant findings. After evaluating my case, the neurology team suggested a possible diagnosis of MS and administered a three-day course of intravenous steroids. While I noticed a slight improvement in some sensory pain, my symptoms persist and continue to vary day by day. I still experience headaches and pressure in my head along with episodes of blurred vision, but there have been no new deficits since treatment. I am reaching out to connect with others who have had similar experiences. I would like to learn about the insights or diagnoses you encountered and what treatments proved beneficial (such as those related to migraine disorders, dysautonomia, or sensory neuropathy, for example). If you have navigated a similar path, I would greatly appreciate your sharing your story. Thank you!
Should I Seek Medical Attention for Left Ear Pulsatile Tinnitus?
A 31-year-old woman reports an ongoing issue with pulsatile tinnitus, which she is currently experiencing solely in her left ear. Although she's noticed this condition intermittently before, she hadn’t paid it much mind due to the absence of pain. Recently, however, her curiosity piqued her interest in researching the condition, where she stumbled upon information suggesting it could be serious. Usually, she avoids searching online for health worries, but now she is contemplating whether a visit to the doctor might be warranted. Can anyone advise on the need for a medical evaluation in this case?
Concerns About Angular Cheilitis
I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.
