Marble-Sized Bump on the Back of My Head
I’m a 25-year-old female, weighing 130 pounds and standing at 5’7”. I don’t consume alcohol or cigarettes, and my only supplements are vitamin C, D3, and grape seed extract. Recently, I discovered a bony bump located on the back of my head. It's hard and roughly the same size as a marble. At times, it can be tender or painful, which leads me to speculate whether it might be a lymph node; however, it does not seem to be mobile. The bump is positioned slightly to the right and near the center of my head. What might this bump indicate? Is this something typical? I appreciate any insights you can provide. Thank you in advance!

It's understandable to be concerned about a new bump, especially when it may be tender or painful. A marble-sized, hard bump on the back of your head could have several potential causes, including:
- Sebaceous Cyst: A small, benign lump that can develop in the skin, often containing a fatty substance.
- Bone Growth: It could be a normal bony prominence, especially if there’s been no recent trauma or injury.
- Lymph Node: While lymph nodes can be swollen or tender during infections, the immobility and bony nature of your bump make this less likely.
- Other Conditions: There are various other skin conditions or benign tumors that might present similarly.
It's important to note that bumps in this area are often benign and not typically indicative of serious health issues.
Next Steps:
-
Monitor: Keep an eye on the bump for changes in size, shape, or level of tenderness. Take note of how long it has been present and any other symptoms, such as headaches or visual changes.
-
Self-Care: Apply a warm compress to the area to help with discomfort. This may also help if there is any inflammation.
-
Limit Irritation: Avoid tight hairstyles or hats that might irritate the bump further.
-
Check for Other Symptoms: Be attentive to any new symptoms, such as swelling in nearby areas, fever, or chills, which could indicate infection.
-
Consider Timing for Further Action: If the bump persists for more than a couple of weeks, grows larger, becomes increasingly painful, or if you notice other concerning symptoms, it would be advisable to seek medical evaluation for potential imaging and assessment.

Intense Pain in Left Thumb
Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.
Persistent Need to Stretch Legs While Seated
I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.
Resources for Safe Mouse Cleanup
While it may not be a typical inquiry for a healthcare professional, I find myself in need of guidance. Recently, we had an uninvited mouse visitor in our home, and unfortunately, it left droppings in my children's toy storage and on the changing table. I am seeking advice on how to effectively disinfect all affected items or determine if disposal is necessary to prevent any health risks. My children are quite young, at 2.5 years and just 4 months old. If they’ve potentially been exposed to mouse droppings, should I reach out to their pediatrician? For reference, I’m a 32-year-old female, standing at 5'6" and weighing 140 pounds, not currently on any medications.
