What Could This Bump Be?
Approximately four years ago, I discovered a small lump located at the inner end of my left collarbone. This bump is firm, does not move, and does not cause any pain; it is roughly the size of a pea. Its size has remained constant, and I’m uncertain if this is something I've had for a long time without realizing it. By the way, I am a 17-year-old female with no known medical issues or relevant family history, and I have a doctor’s appointment coming up soon.

It's good that you are aware of the bump on your collarbone and have a doctor's appointment scheduled soon. The characteristics you describe — a firm, non-painful, immobile lump that has not changed in size over four years — are important indicators for evaluation.
Explanation
There are a few possible explanations for a bump like this on your collarbone. It could be a benign growth, such as a lipoma (a fatty tumor), an epidermoid cyst, or a lymph node that has not been reactive. These are typically harmless, especially considering your age and the stability of the lump. However, it’s wise to get it checked, as only a healthcare professional can assess it accurately.
Next Steps
- Monitor for Changes: Keep observing the lump until your appointment. Note any changes in size, shape, or if you develop any pain, redness, or warmth around it.
- Prepare for Your Appointment: Write down the history of the bump, including when you first noticed it, any changes over time, and any other symptoms, even if they seem unrelated. This information will help your doctor.
- Avoid Self-Diagnosis: While research is good, it's best to avoid jumping to conclusions about what the bump could be. Your doctor will perform a physical exam and may recommend imaging studies or other tests if necessary.
Stay calm, as most lumps like this in young individuals turn out to be benign. Your upcoming appointment will provide you with clarity and peace of mind. Let me know if you have more questions!

Seeking Direction Amid Ongoing Health Challenges
Greetings, I find myself in a challenging situation, grappling with persistent and escalating symptoms for over two years. Despite numerous visits to various healthcare professionals, all I have received are blood tests that indicate I’m in good health, often attributing my discomfort to anxiety and depression. I feel utterly fatigued, detached, and not at all like my true self, which has driven me to seek advice on my next steps. Here are some key details about my health history: - I am a 30-year-old woman. - I was diagnosed at birth with beta thalassemia minor and Gilbert’s disease, resulting in hemoglobin levels consistently in the 9s. - Most recently, I have been diagnosed with binocular vision dysfunction and accommodative dysfunction, and I will be beginning vision therapy next week. - I have a history of traumatic brain injury without experiencing loss of consciousness. - I have been evaluated for Lyme disease and rheumatoid arthritis. Over the course of the last two years, I have experienced numerous symptoms, including but not limited to: - Profound fatigue that requires me to take midday naps just to get through the rest of the day; it's far beyond simple tiredness. - A sensation as if I am wading through thick syrup. - Tongue tingling. - A peculiar feeling in my hands, akin to having rubbed them against a rough surface. - Tingling or numbness in my right big toe. - Numbness and tingling in my arms. - My right arm often feels heavy and challenging to use; even small tasks like grabbing toilet paper can be daunting. - Confusion characterized by two competing thoughts; part of my mind grasps the situation while another part struggles to keep track, leading to fears of losing consciousness of my surroundings. - A clear runny nose, the sensation of water when bending over or practicing yoga. - A pervasive sense of malaise, as if I’m on the brink of illness, but it never materializes. This feeling has been with me throughout my life. - A tingling sensation in my arms and legs reminiscent of a high. - Visual disturbances linked to my new diagnosis of binocular vision dysfunction. - Consistent feelings of derealization, affecting me daily. - Occasional ear popping reminiscent of the sensation during takeoff on an airplane, lasting for hours. - Ringing in my ears. - Heart palpitations. - Sudden vertigo episodes that create the illusion of spinning or rocking as if I were on a boat. - Near-daily headaches concentrated around my eyebrows or a feeling of pressure at the back of my head. - Intermittent sharp pains extending from the occipital area to the top of my head and temples. In my search for relief, I have tried several approaches, including: - Weekly therapy focused on addressing my anxiety, depression, and past trauma. - Various supplements, such as Vitamin C, omega-3s (EPA/DHA), Vitamin D, magnesium glycinate, and ashwagandha. - Engaging in yoga and pilates. - Practicing meditation. - Allowing myself to rest instead of resisting my body’s pleas for downtime. I genuinely need support and direction as this situation is profoundly affecting my daily life. My world feels increasingly restricted, making it difficult to maintain a balance between my full-time job, home responsibilities, and personal relationships. I fear there may be no escape from this struggle, and I’m searching for a glimmer of hope on the horizon.
Concerns About a Black Spot Near My Nail Bed
Greetings! I’m a 30-year-old man weighing 175 pounds, and I’m generally in good health with no current medications. Recently, I observed a small black spot situated near the bed of my fingernail.

Concern Over Pulsating Pupils
Hello! I’m a 21-year-old female diagnosed with gastroparesis and POTS, currently taking 20mg of esomeprazole. I recently discontinued my prucalopride at 2mg and am also on birth control. I’m quite accustomed to experiencing a range of random symptoms, which typically don’t alarm me given my existing health conditions. However, while I was showering earlier, I felt surprisingly drained and somewhat dizzy, even though I was seated. I didn't think much of it initially because of my POTS. Upon finishing my shower, I checked my reflection and noticed that my pupils were pulsating noticeably, expanding and contracting in quick succession. I also have a persistent ringing in my ears along with a peculiar sound that's hard to pinpoint—similar to binaural tones—and I feel a pressure in my head. Although I’m fatigued, I’m also feeling a little disoriented. Should I consult a healthcare professional about this, or will it likely subside on its own? Thanks for your advice!
