Painless Hard Lump Under Chin: Seeking Guidance
I'm an 18-year-old male experiencing something concerning. I've discovered a firm, immovable lump under the chin, roughly the size of my fingertip. It's situated near the base of my chin, so close to the bone that it's hard to distinguish where the bone ends and the lump begins. This recent finding has left me feeling extremely scared and anxious. The thought that it could be something serious, like cancer, terrifies me. I'm on the verge of breaking down into tears from worry. To add to my anxiety, I've been struggling with the possibility of having blood in my stool for the past few months. I've already undergone several tests, including an ultrasound, a calprotectin test, and a fecal occult blood test, and I'm set to have a colonoscopy scheduled for August. My current fear is that I might have metastatic cancer! There have been small instances of bright red blood appearing about once a week. Despite the ultrasound showing no abnormalities and the calprotectin test returning normal, I still fear the worst. Given my age, it seems unlikely that cancer could have progressed to such an advanced stage so quickly, right? It can't go from unnoticeable to life-threatening within mere months, especially since I haven’t experienced any other symptoms. I truly need support; my anxiety is overwhelming right now.

I understand that discovering a lump under your chin and dealing with concerns about blood in your stool can be incredibly worrying. Let's break down your situation and address your anxieties one step at a time.
Main Points:
- The lump under your chin could be a benign condition, and many lumps in that area are not cancerous.
- Your ongoing digestive symptoms and the upcoming colonoscopy are important for addressing your health concerns but are unlikely to indicate advanced cancer at your age.
Explanation:
-
Lump Under Chin: The firm, immovable lump you're feeling could be a benign lymph node, cyst, or other non-cancerous growth. Lumps near the chin can result from an infection, inflammation, or even normal anatomical variations. It's reassuring that the lump is painless, which often indicates it's less likely to be serious.
-
Blood in Stool: Having intermittent bright red blood in your stool can be alarming, but it can also stem from less serious causes such as hemorrhoids or anal fissures. The tests you've undergone, especially the ultrasound and calprotectin test, returning normal are encouraging signs. They suggest that serious conditions have been adequately ruled out.
Next Steps:
-
Monitor the Lump: Pay attention to any changes in size, shape, or feel of the lump. If it remains the same, it’s often a sign of something benign. Continue to maintain regular check-ups to ensure it is properly assessed.
-
Prepare for Your Colonoscopy: Focus on the preparation for your colonoscopy that's scheduled for August. This procedure can provide valuable information about your digestive health. Understand that the likelihood of advanced cancer in your age group is low, especially since you've had normal lab results.
-
Address Anxiety: It’s crucial to manage your anxiety during this uncertain time. Consider engaging in relaxation techniques such as deep breathing, meditation, or talking to someone who can provide support, like a friend or family member.
-
Symptom Diary: Keep track of any new symptoms that may arise, including changes in your bowel habits, the characteristics of the blood, or any other health changes. This can help you communicate effectively with healthcare providers during your next appointments.
You’re not alone in feeling anxious, but remember that many cases like yours turn out to be non-threatening. It's commendable that you're actively seeking information and support, so keep being proactive about your health.

Health Troubles: An Overview
Hey everyone, let’s break this down: - **Profile**: 46 years old, 6'1" tall, weighing 320 pounds. - **Medical History**: In January 2023, I experienced severe pain from a kidney stone and ended up in the emergency room. They admitted me due to anemia, during which I received 4-5 iron infusions and 3 blood transfusions. I also underwent an endoscopy, swallowed a pill with a camera, and had a colonoscopy. These procedures revealed two small ulcers above the stomach. I was recommended to take antacids indefinitely, although my first refill was amusingly denied. Additionally, I was instructed to take iron supplements. Overall, I spent around three days in the hospital and had been intermittently feeling fatigued, likely linked to my anemia. - **Current Symptoms**: 1. **Pitting Edema**: This was observed during my hospital stay, but no action was taken. Nurses would occasionally check my legs, make observations, and leave without further comment. I can alleviate the swelling by elevating my legs and wearing compression socks, but it remains uncomfortable. 2. **Fatigue**: If I attempt to walk more than 20 yards, my heart starts racing, and I quickly feel exhausted. A bit of heavy breathing follows, but it settles down after a moment. I used to easily walk 2-4 miles, but now I struggle just to make it through the grocery store. 3. **Audible Heartbeat**: When exerting myself as described above, I can hear my heartbeat in my ears. 4. **Decreased Appetite**: This change is recent; I hardly feel hunger at all. I'm skipping meals simply because I have no desire to eat. 5. **No Known Conditions**: I don’t have any diagnosed issues related to sleep apnea, or problems with my heart, kidneys, or liver. 6. **Dermatitis in the Perineum**: I’m uncertain if this is connected to my other symptoms. It’s not ringworm or jock itch, but I’ve had this condition for several months and recently started applying 1% hydrocortisone. While scratching provides some relief, it tends to elevate my heart rate and may contribute to my other symptoms. 7. **Erectile Dysfunction**: This is a mild case that I’ve never encountered before. I’ve read that inflammation from the dermatitis could potentially lead to this issue, but I’m uncertain if there's a link. That’s my current situation. I’m feeling a bit lost regarding which healthcare professional to consult next—should I reach out to my primary care physician? On top of everything, I no longer have insurance since my previous plan’s provider started charging without notifying me, and five months later, I received a termination notice. Fantastic, right?
Are My Foot Veins Normal? Should I Worry?
At 23 years old, I stand 6 feet tall and weigh 150 pounds—currently enjoying a family vacation. My mom recently remarked that the veins in my foot appear quite unusual, almost as if there's a problem. While I haven't given much thought to the appearance of my feet, I do agree they look a bit peculiar. Is this something I need to be worried about? During the flight, I experienced some numbness in my feet, but aside from that, they feel perfectly fine. I'd appreciate any insights to ease my concerns. Thanks a lot!
Concerns About Dark Stool Color
I am a 29-year-old male weighing 235 pounds. I am not currently on any medication, but I do consume alcohol and use vape products. Yesterday at around 6 PM, I noticed my stool had a dark, tar-like color. This followed an eventful long weekend where I celebrated the 4th of July and indulged in excessive drinking. Since then, I have had additional bowel movements which returned to a typical brown color, although they have been somewhat loose and irregular. I haven't experienced any abdominal discomfort. Previously, I was experiencing significant nausea and had difficulty keeping fluids down for some time. Today, I have managed to rehydrate with several servings of Gatorade and water, and I’ve managed to eat a little, although not to the extent that I normally do.
Permanent Hole After Cyst Removal
I'm a 33-year-old male, standing 6 feet tall and weighing 180 pounds. I have never smoked, nor do I use any drugs or alcohol, and I'm not on any medication. As described in the title, I’ve had a small cyst, roughly the size of a pea, located in the center of my lower back for as long as I can remember. At one point, my wife decided to try to extract it. After we applied some pressure, it became infected and painful for a few days. Once the swelling subsided, I was under the impression that the cyst was completely eliminated. It seems we may have ruptured it beneath the skin since there’s no longer any noticeable cyst. However, I’m left with a permanent indentation, which has raised concerns for me. Although the hole itself isn't causing any problems, my online searches about it have been unsettling, as I’ve encountered alarming information. Currently, I’m awaiting a referral to see a dermatologist. I wonder if there is anything they can do regarding this hole. What can I anticipate during the visit? Is surgical intervention necessary to address it? Can this issue be resolved?
