Experiencing Numbness in My Left Thumb Since Friday

2/3/2026, 7:10:21 PMMale25-34

Age: 18, Height: 5’9, Weight: 230 lbs. Last Friday, I spent an extended period playing the guitar. While engaged in playing, I didn’t recognize any issues, but as I got ready for bed later that night, I began to experience numbness in my left thumb. More precisely, it's the left side of my thumb that feels completely numb, while the right side remains unaffected. I'm leaning towards believing that this is related to nerve complications. I plan to consult a professional soon, although it may take a few days before I can do so. In the meantime, I’d appreciate any insights or recommendations regarding what might be causing this or any activities I should avoid. As an additional note, the condition has not shown any signs of improvement; in fact, today seems to be the most severe it has been thus far.

It sounds like you’re experiencing numbness in your left thumb, which can be concerning, especially at your age. This issue may be related to nerve compression or irritation, particularly after extended activities like playing the guitar. It’s good that you’re planning to consult a professional soon. Here’s a structured approach for what you can do in the meantime.

Main Points:

  • Numbness in your thumb is likely related to nerve compression from prolonged activity.
  • Immediate self-care can help manage symptoms and prevent worsening.

Explanation:

Numbness in a specific area, like your thumb, could result from several factors, including:

  • Nerve Compression: This often happens due to repetitive strain or awkward positions (like how you hold your guitar).
  • Circulation Issues: Sometimes, blood flow can be restricted, leading to numbness.
  • Injury or Strain: Overexerting muscles around the hand can lead to temporary nerve irritation.

Given that it started after prolonged use of your thumb, it's likely you may have irritated a nerve.

Next Steps:

  1. Rest Your Hand: Take breaks from playing the guitar and avoid any activities that require significant use of your left hand, especially gripping or strumming.

  2. Modify Your Position: When you do play, adjust your posture and hand position to relieve pressure on the nerves.

  3. Gentle Stretching: Perform finger and wrist stretches gently to promote circulation and relieve tension. Try moving your fingers in circles and flexing your wrist lightly.

  4. Cold Compress: Apply a cold pack to your thumb for 15-20 minutes every few hours to reduce any swelling or irritation.

  5. Monitor Symptoms: Keep track of your symptoms. If the numbness worsens, or if you experience other symptoms like weakness or pain radiating from your arm, this information will be useful for your healthcare provider.

It's important to listen to your body and give yourself time to rest. If symptoms continue or worsen, ensure you follow up with a professional evaluation as soon as you can. Take care!

A Decade on Trimethoprim: Is This Common?

As a child, I faced significant health challenges related to severe reflux, which led to frequent urinary tract infections and bladder issues. Consequently, I was prescribed trimethoprim when I was around one year old. I took this medication for about ten years—possibly even longer—until I reached the age of eleven. At that point, I decided I could no longer tolerate it, primarily due to its unpleasant taste, and stopped taking it. To my surprise, the doctors agreed that it was fine to discontinue the medication. What puzzles me is how I remained on this medication for such an extended period without any follow-up evaluations. I've learned that it's not uncommon for doctors to prescribe long-term, low-dose medications, but they should conduct regular checks for potential deficiencies in patients. I cannot recall a single instance where any blood tests or assessments were performed during my decade-long treatment. Moreover, trimethoprim had adverse effects on my health, particularly impacting my eating habits. The taste aversions I developed during this time had a lasting effect, making it challenging for me to eat foods I used to enjoy. Even now, I continue to struggle with oral thrush and odd taste preferences. According to my parents, I had a wide-ranging appetite as a baby, which changed dramatically once the medication was introduced. When we brought my concerns to the attention of my healthcare providers, they seemed dismissive, and all I received was a patronizing appointment with a dietician who asked if I understood the basic nutritional categories. I’m curious to learn how typical my experience is. Has anyone else been on trimethoprim for a long time without oversight, and have you encountered similar long-term effects on taste?

Withdrawal Symptoms from Klonopin: Insights and Experiences

I am a 36-year-old male, standing at 3'10" and weighing 100 pounds, with a Caucasian background and currently not taking any medications. Recently, I was prescribed Klonopin to manage anxiety, but I discontinued its use just a few days ago. What I discovered was that instead of alleviating anxiety, it essentially functioned as a sedative, which I knew posed a significant risk of dependency, a concern that ultimately became a reality for me. Since stopping Klonopin, sleep has eluded me for the past 48 hours. Fatigue has become overwhelming; whenever I lie down and shut my eyes, I quickly drift into vivid dream-like states that feel real, yet I remain fully conscious and awake. Emotionally, I find myself in turmoil. Reflecting on cherished individuals or beloved pets triggers immediate tears. Conversely, even the smallest and most mundane annoyances send me spiraling into extreme bouts of anger. These intense emotional responses can dissipate just as suddenly as they arise, often without a clear reason. My heart rate seems to surge unexpectedly; my smartwatch indicates it fluctuates around 140 beats per minute. However, when I measure my blood pressure, it appears to be within the normal range, generally in the 120s over 70s. Additionally, I'm grappling with a persistent headache. As a double amputee, I've noticed that my phantom limb sensations have intensified, although I attribute this partly to the withdrawal from Klonopin, as it had an influence on those sensations. Is this an expected manifestation of withdrawing from Klonopin?

Severe Arm Bruising Concerns

A close family acquaintance, a 59-year-old male, is currently navigating a health issue without insurance, and I'm attempting to assist him in identifying the problem. He has a history of taking blood thinners and ibuprofen. Recently, while lifting something substantial, he felt a pop in his arm just a day ago. Now, he is experiencing significant discomfort and has a restricted ability to move his arm. The bicep area appears to be swollen with distinct purple and red markings. I have a strong suspicion that he may have injured the muscle in his arm, but the extent of the swelling makes it challenging to determine the exact issue.

Guidelines for Bathing After Circumcision in the UK

I am a 21-year-old male, weighing 89 kilograms and standing at 5 feet 11 inches. My medical regimen includes taking levothyroxine. I do not smoke or consume alcohol. It has been 13 days since my circumcision, performed to address phimosis. Initially, I experienced slight bleeding due to a loose stitch, which prompted a visit to my general practitioner. After an evaluation, it was determined that no action was necessary, and since then, my healing process has been progressing well. However, I have encountered varied guidance online from NHS sources regarding when one may resume bathing after such a procedure. Some recommendations suggest avoiding baths for at least two weeks, while others indicate that it's acceptable to bathe shortly after—as long as the duration is limited to five minutes at a time and showers are often preferred. The stitches are healing properly and are beginning to dissolve as expected at this stage. I am curious about the optimal and safest time frame for me to take a bath without risking complications or hindering my recovery process.

Chronic Nausea for Seven Years

My daughter, who is now 23, has been struggling with persistent nausea since the age of 16. Initially, she experienced considerable weight loss, prompting us to seek medical advice. After visiting her primary care physician, she was referred to a specialist in gastrointestinal issues. They performed an endoscopy, but the results showed no abnormalities. Consequently, she had to manage her condition on her own. Over time, she adapted to the persistent nausea and began using Zofran nearly every day. We later discovered that her symptoms seemed to coincide with the initiation of the depo shot for contraception. After switching to birth control pills, she noticed slight improvements, but her symptoms have worsened again as time has progressed. A few months ago, she underwent blood tests, including evaluations for food allergies, but everything came back normal yet again. At this stage, I am at a loss regarding the next steps or which specialist to consult. She experiences bouts of nausea primarily after meals, impacting her comfort. Despite this, she has adapted enough to remain functional, especially since she regained the weight she lost within a year. I am feeling quite helpless in this situation. Any suggestions or advice would be greatly appreciated.
