What Could a Firm Bump Near the Tailbone Indicate?
I am an 18-year-old female, standing at 5 feet 5 inches and weighing 120 pounds. Recently, I have become aware of a hard protrusion that is located to the left of my tailbone, resting beneath the fatty tissue of my buttocks. When I touch it, it feels incredibly solid and nearly indistinguishable from the underlying bone. There is no accompanying fluid, itchiness, or noticeable swelling, except for discomfort when I sit awkwardly or make direct contact with it. I’ve heard about pilonidal cysts and recognize that I lead a fairly sedentary life, but given the bump's density and firmness, I'm uncertain if it fits the description of a pilonidal cyst. What might this bump be, and should I be concerned about its urgency?

A firm bump near the tailbone can have several potential causes, and it's good that you're paying attention to your body. In your case, the characteristics you've described—its firmness, location, and the absence of fluid or noticeable swelling—suggest it may not be a typical pilonidal cyst, but rather something else, such as a lipoma (a benign fatty tumor) or a fibroma. However, an exact diagnosis would require a physical examination.
Explanation
- Pilonidal Cyst: This is often soft and can involve fluid; it typically presents with pain and swelling.
- Lipoma: This is a benign growth of fatty tissue that is usually soft and movable beneath the skin.
- Fibroma: A fibrous tumor that can feel firm and might develop in the area of the tailbone.
Given that you are experiencing discomfort when sitting and there is no significant swelling or redness, the bump may not be an urgent concern, but it is worth keeping an eye on.
Specific Next Steps
- Monitor the Bump: Keep track of any changes in size, shape, or discomfort levels over the next few weeks.
- Avoid Irritation: Try to sit on soft surfaces and adjust your sitting position to minimize pressure on the bump.
- Self-Management: Over-the-counter pain relief can help with discomfort if needed; options include acetaminophen or ibuprofen, following package instructions.
- Consider Activity Variation: If you're leading a sedentary lifestyle, look into incorporating more movement. Regular activity can improve circulation and potentially ease discomfort.
- Documentation: Take note of any changes or new symptoms. If the bump changes drastically—such as increasing in size, becoming painful, or showing signs of infection (redness, warmth)—it may require further evaluation.
If you notice any concerning changes, don't hesitate to seek medical advice for a proper evaluation and guidance. Let me know if you need further information or have additional questions!

Could Regular Hookah Use Lead to Reddish Urine or Other Health Concerns?
At 22 years old and typically in good health, I've made some recent changes to my habits. After quitting cigarettes, I now find myself smoking hookah nearly every day—about one session daily—for the last couple of weeks. I don’t consume alcohol frequently and make an effort to stay fit. However, I've recently observed that my urine has taken on a slightly reddish hue. While I don’t experience any significant pain or discomfort, it certainly raises some red flags for me. Is it possible that my hookah usage is responsible for this change? Additionally, what other potential health risks should I consider when it comes to daily hookah smoking?
Persistent Headaches: Seeking Answers
I’m a 34-year-old male, weighing 180 pounds, and I don’t typically have any health concerns. I do engage in vaping and consume alcohol, but I've refrained from drinking for the past three days. I recognize the need for medical advice and plan to consult my GP tomorrow. For the last week, I've been experiencing a headache that fluctuates in severity, sometimes nearly vanishing but still lingering for a full seven days, which has been quite draining. This discomfort is nearly constant and can occasionally be quite severe. Interestingly, I’ve noticed that playing hockey provides a temporary relief from the pain, at least for a short while afterward, but I end up needing to take Tylenol again. I had a drink last Sunday, which I regretted when I woke up with a terrible headache on Monday. In terms of hydration, I’ve been diligent, drinking over three liters daily and incorporating electrolyte beverages into my routine. This headache situation is unusual for me. Just yesterday, I underwent an eye examination to rule out any strain, and the results came back normal. With two young children and the stresses of life, combined with my job that requires working on a laptop, things can get hectic. However, I’m not experiencing any additional symptoms like flashes, double vision, or weakness that might indicate a stroke or cognitive decline. It’s primarily this nagging headache that’s persisted longer than I’ve ever experienced before. Naturally, I’ve contemplated potential neurological issues, although I’m not overwhelmed with fear about it. I would appreciate any insight you have regarding what might be happening.
Desperate for Answers: My Ongoing Health Struggle
**Age:** 30 **Gender:** Male **Height:** 6 ft 2 in **Weight:** 83 kg I reside in the UK where I lead a lifestyle devoid of smoking or recreational drug use and indulge in alcohol only on rare occasions. Despite being prescribed Amitriptyline and Nortriptyline, I haven’t experienced any relief from my symptoms. **Background:** My health issues have persisted for over two years. I’ve undergone numerous consultations with general practitioners and specialists, yet none have arrived at a diagnosis. Initially, my ordeal began with severe jaw pain that quickly radiated to my head and then throughout my entire body. This followed traumatic events in my life, including my mother’s attempt at suicide, her subsequent hospitalization, my brother’s suicide, and an incredibly stressful relocation. Doctors initially diagnosed me with a sinus infection, later contemplating a blocked salivary gland before reverting back to the sinus diagnosis. I endured a year of antibiotics, steroids, and antifungal treatments, which did nothing to alleviate my suffering. In desperation, I requested an MRI, fearing I might have a brain tumor or something equally dire. The results revealed little aside from a minor sinus infection. An ENT specialist subsequently conducted a CT scan, confirming no signs of infection or allergies. He did inquire if I had a history of nasal fractures, to which I responded negatively. Following this visit, I was left without further direction. As I sought help, I also visited both an optometrist and a dentist, hoping they might uncover any issues contributing to my symptoms. While my vision appeared fine, I occasionally experienced blurred sight along with tiredness, headaches, and migraines. The dentist assessed my dental health due to my jaw and tooth discomfort, finding nothing amiss but suggested a mouthguard to address potential teeth clenching, which has not proved effective. With the focus so heavily on my head, I lost touch with the overall state of my body. Once I began to reassess how I was feeling physically, I realized my symptoms were more extensive than I had acknowledged. After a comprehensive evaluation of my body, I compiled the following symptoms I currently endure: * Pain stretching from my forehead to the area behind my ears. * A blocked right nostril, although the ENT remarked that the deviation affects my left side. * Dry sinuses. * Pain localized on the right side of my jaw, which can radiate to the opposite side. * Discomfort extending down my left shoulder. * Cracking and sore joints in my left shoulder. * Aching and cracking joints in my knees. * Similar issues in my ankles. * Widespread muscle soreness resembling flu-like symptoms. * Puffy and fatigued eyes. * Frequent headaches. * Migraines causing intense pain in my right eye. * Neck discomfort. * Occasional sharp pains in various parts of my body or limbs. * Digestive distress. * A recent sore throat. * A peculiar sensation while swallowing, especially on the right side. * Persistent brain fog. Currently, my GP's only action is to refer me to a rheumatologist, suspecting the possibility of fibromyalgia, a condition my mother has, often triggered by traumatic physical or emotional events. In terms of mental health, I have pursued therapy extensively, although it has failed to alleviate my physical symptoms. I find myself at an impasse regarding my health, feeling as though my body is failing or at war with itself. The quality of my life has diminished significantly. At this point, I can only hypothesize that my issues may stem from an allergy or some sort of fibromyalgia, or perhaps an unusual condition that remains unidentified. Any guidance or insight would be immensely valued as I am at the end of my rope.
Girlfriend's Unusual Nighttime Behavior
The title sums it up fairly well, but to clarify, she’s not under the influence of drugs or alcohol. I'm an 18-year-old female, and my girlfriend is 17; we’ve been together for two years and often fall asleep on FaceTime. However, at approximately 2:30 am this morning, I woke up to the peculiar sound of her conversing with herself. Initially, I believed she was speaking with a family member, but after texting her, it became evident that none of her messages made any sense. She seemed to think she was having a conversation with her boss, then transitioned to speaking to me, and then shifted focus to a friend—while she repeatedly called her sister by my name. Throughout this entire episode, both her mother and I were receiving messages from her that were completely incoherent. Despite our pleas for her to lie down and get some sleep, she stubbornly refused to rest. There’s no prior instance of her talking in her sleep or walking around at night, and she doesn't seem to be asleep either, as her eyes are wide open and she is moderately engaged in conversation with me via FaceTime. From my perspective, her thoughts appeared to be scattered, resulting in a delay in her response to each question, with her replies often lacking clarity. Her texts, on the other hand, were utterly nonsensical. Here’s one example of a text I received: "I jofijtnanxart but then oinlose it somewhere in my house and then mad could elk like wehstsbhenfonnwndo." Anyway, does anyone have any insights into what might be happening? This has been going on for at least four hours now.
Understanding Bilateral Adenexal Lesions and Pelvic Fluid: Should I Be Concerned?
I’m experiencing a notably enlarged uterus packed with extensive uterine fibroids. One particularly large fibroid, which is subserosal, measures up to 14 cm and protrudes from the top of the uterus, reaching into the mid-abdomen. Alongside this, there are additional enhancing lesions located in the bilateral adnexa and potentially subserosal fibroids in that area. My doctor has advised an MRI of the pelvis for a more thorough assessment. Additionally, there is some free fluid in the pelvic cavity, which is likely a normal finding for someone in my reproductive age group. However, I am particularly worried about the lesions in the adnexal region and the free fluid. Could these signs point towards something serious, or are they simply related to the fibroids? My instincts suggest there may be an underlying issue, given the other symptoms I’ve been experiencing, but of course, I hold hope for a positive outcome. To elaborate, my other symptoms include weight loss, discomfort in the groin area, and back pain, which accompany typical fibroid-related symptoms such as bloating and abdominal pain. Initially, a CT scan was requested in June, but insurance denied it. Then, in July, my primary care physician ordered an ultrasound due to my abdominal discomfort. Later in July, a gastroenterologist recommended a CT scan of the abdomen and pelvis because of my unexplained weight loss and ongoing constipation. Recently, my gynecologist ordered an MRI of the pelvis to evaluate the situation prior to discussing potential surgical options.
