Strange Lump on Sole of Foot

8/14/2025, 8:00:57 AMMale25-34

At 18 years old and assigned male at birth, I've recently noticed a peculiar lump on the sole of my foot. This small nodule is firm to the touch and causes pain when I apply weight on it. Although I suspect it might be a blister, I'm uncertain about its nature. The area seems to have a whitish appearance just beneath the skin's surface.

It sounds like you've developed a lump on your foot that is causing you pain, especially when pressure is applied. This type of lump can have several causes, including a corn, a plantar wart, or a callus. It’s important to address this discomfort and understand what may be happening.

Explanation:

  • Firm Nodules: A nodule that is firm to the touch and painful when weight is applied could be a plantar wart caused by the human papillomavirus (HPV), or possibly a callus or corn resulting from friction.
  • Whitish Appearance: The whitish color you notice might indicate thickened skin or the presence of a wart, which typically has a rough surface and may appear as a hardened lump.

Next Steps:

  1. Reduce Pressure: Try to avoid putting weight on the affected area. Wearing comfortable shoes with cushioning or using pads can help alleviate some discomfort.

  2. Soak and Moisturize: Soak your foot in warm water for 10-15 minutes daily to soften the skin. After soaking, gently exfoliate the area with a pumice stone or foot file. Moisturize the area after soaking to keep the skin supple.

  3. Monitor Symptoms: Keep an eye on the lump for any changes in size, color, or pain level over the next week. If it worsens or does not improve, consider your next steps carefully.

  4. Home Treatment Options:

    • If you suspect it may be a corn or callus, you can consider over-the-counter treatments designed to soften the skin.
    • For plantar warts, topical treatments containing salicylic acid can be beneficial.
  5. Maintain Hygiene: Ensure your foot stays clean and dry, as moisture can worsen skin issues.

If the lump does not improve with home care or starts to cause significant pain, consider seeking professional evaluation to determine the exact nature and best treatment options. Keep observing how your foot responds to these measures, and prioritize what makes you comfortable.

Inquiry About Dental Procedures Before Major Surgery

Recently, my mother made a sudden decision to undergo a total dental extraction. She had her upper teeth removed approximately two weeks ago, and just yesterday, the lower ones were taken out. She is slated for a pre-operative assessment on Monday morning, ahead of a significant back surgery scheduled for Tuesday, which may last between eight to ten hours and necessitates intubation. I am curious about the likelihood that her doctor might postpone the surgery due to her recent dental procedure. This concern is heightened as we have booked a hotel and my husband has arranged to take two days off work for this event. Although I am still within the timeframe to cancel our hotel reservation, I am hesitant to do so if her surgery is still on track. To give a bit more context, my mother is a 54-year-old Caucasian woman, standing 5'6" and weighing 160 pounds. She does not consume alcohol, has been a potential smoker, and recently (a few months back) ceased using drugs (meth) as mandated by drug court. As far as I know, she isn’t currently prescribed any medications, apart from possibly antibiotics and Lortabs following her tooth extractions.

Abrupt Onset of Eye Discomfort

I’m a 23-year-old male with a history of slight near-sightedness but no other significant eye problems. About three days ago, I woke up to find that my eyes felt intensely painful, similar to the sensation one experiences after a lack of sleep. Although I've been getting ample rest each night, this discomfort hasn't subsided. Both eyes are affected equally without any redness, burning sensations, or visual disturbances. The soreness is quite pronounced, making it challenging to concentrate on everyday activities.

My Relationship with Milk Consumption

For nearly two decades, I have predominantly relied on milk as my primary source of hydration, consuming around five liters daily. Although I recognize that this reliance might not be the healthiest choice, my low appetite has perpetually left me underweight. In the past, I attempted to transition to drinking water; however, I noticed a concerning drop in weight along with persistent fatigue. My inquiry is whether there exists a more nutritious method to obtain calories without resorting to solid foods, and ideally, without incurring high costs?

When Can I Expect to Drive Again?

I’m a 35-year-old who suffered a spiral fracture in my right leg affecting both the fibula and tibia.

I’ve noticed that my leg is beginning to regain sensation, with improved control over my ankle and feeling returning to the sole of my foot. Given this progress, what is a realistic timeframe for when I might be able to drive safely once more?

Interpretation Request for Recent Spinal NM Bone Scan

Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
