Curious Case of an Under-Skin Muscle Indentation

3/27/2025, 4:40:26 AMMale25-34

I've been living with this peculiar condition for as long as I can recall, and I'm bewildered about its origin. There's a small indentation situated on my upper right arm. It seems like there's a hollow area in the muscle, yet the skin above it appears completely intact. Remarkably, there are no external indicators of any issue on the skin surface. Occasionally, it feels tender to the touch, and on rare occasions, I experience pain that lasts for a day or so. I can't remember ever sustaining an injury in that spot, nor can I identify any possible cause for this anomaly. Update: The only indication of this condition is the noticeable dip when I palpate the surrounding region. If anyone has any insights or suggestions, I would greatly appreciate your feedback in response to the automated message.

It sounds like you're describing a muscle indentation in your upper right arm that feels tender at times and causes occasional pain. This kind of muscle indentation can be unusual, but there are a few potential explanations to consider. Most notably, it could be related to muscle atrophy, nerve issues, benign tissue changes, or even a previous unnoticed injury.

Possible Explanations:

  • Muscle Atrophy: Sometimes, muscles can develop indentations from disuse or from a lack of strength.
  • Nerve Involvement: Nerve conditions can occasionally cause localized muscle issues or differences in muscle tone.
  • Benign Masses: There may be a benign lipoma or some other kind of tissue change that isn't visible on the surface of the skin.
  • Previous Mild Injury: It’s possible to have inflammation or change without remembering an injury.

Next Steps:

  1. Monitor Symptoms: Keep track of any changes in the indentation, tenderness, or pain. Note when it occurs and any activities that precede it.
  2. Gentle Massage: Consider gently massaging the area to promote blood flow, which might alleviate some tenderness.
  3. Strengthening and Stretching: Incorporate light strength training and stretching for your arm muscles to see if improving muscle tone makes a difference.
  4. Avoid Strain: Be cautious with any activities that may aggravate the area, and listen to your body regarding pain.

If the symptoms intensify or do not improve, consider keeping a record of your observations and seek further evaluation if necessary. Understanding any underlying issues could require an examination or imaging, which would help clarify what you’re dealing with. Let me know if you need further guidance!

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?

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!
