What is the Timeline for Dry Gangrene Development on a Tightly Bound Pinky Finger?
A 14-year-old, standing at 142 cm, notes that after a duration of 6 hours and 30 minutes, there appears to be no significant damage to the pinky finger, which has been secured tightly with a rubber band. The individual has not released the pressure on the finger at any point during this time.

It's great that you're being proactive about understanding the situation with the pinky finger. When tightly bound for an extended period, significant concerns related to blood flow restriction can arise, including the risk of dry gangrene, which occurs when tissue dies due to lack of blood supply.
Main Points
- After 6.5 hours of tight binding, there's still risk of tissue damage.
- Dry gangrene can start developing when blood supply is significantly compromised for an extended time.
Explanation
When blood flow is restricted, the affected area can become damaged due to a lack of oxygen and nutrients, which can lead to tissue death (gangrene). The timeline for damage can vary based on several factors, including the tightness of the band and individual blood flow conditions. While you might not see visible signs of damage yet, it's essential to be aware that changes can occur quickly after prolonged pressure.
Next Steps (Prioritized Actions)
-
Release the Pressure Immediately: Gently remove the rubber band to restore blood flow to the finger. This action is crucial to prevent further damage.
-
Monitor Changes: Watch for any changes in color (pale or dark), temperature (cold or warm), or any pain in the finger after releasing the band.
-
Move the Finger: Begin moving the finger gently to encourage blood flow. Look for signs of swelling or discoloration.
-
Hydration: Drink water, as hydration can assist general blood flow and health.
-
Seek Help if Necessary: If the finger does not return to normal color quickly, or if you notice any severe signs such as intense pain, severe swelling, or if the finger becomes black or blisters develop, it’s advisable to seek medical attention promptly.
Keeping these points in mind can help mitigate risks and ensure that your pinky finger receives the care it needs. Let me know if you would like to discuss anything more specific!

Severe Pain and Swelling in Armpits: Need Immediate Relief
Age 21, currently prescribed Bupropion and Zoloft, along with a birth control pill. I am feeling completely overwhelmed by this predicament. Although I have sensitive skin, this level of discomfort is unprecedented for me. I suspect that a combination of excessive scratching, vigorous washing with my sponge, shaving, and applying a hydrating (alcohol-free) deodorant has caused a serious reaction in my armpits. As highlighted in my headline, they are not only swollen but exhibit a purplish hue and are incredibly painful. It feels as though the skin is severely chapped, making even the slightest movements excruciating, often reducing me to tears. I attempted to alleviate the situation by washing the area and applying aloe vera gel designed for soothing irritations, but the discomfort persists. I took a lukewarm shower and slathered my armpits with an excess of Vaseline, which provided a small amount of relief, yet the pain is still significant. I recognize that I may need to simply be patient and allow time for healing, but the intensity of the pain is unbearable at this moment. Is there anything I can do to ease this pain before my appointment with the doctor tomorrow morning?
Understanding Lateral Translation at the C1-C2 Joint: A Cause for Concern or Not?
At 29 years old, weighing 185 pounds and standing 6 feet tall, I recently underwent a digital motion X-ray while consulting several healthcare professionals aimed at uncovering the source of my persistent headaches. The results indicated a lateral translation measuring 5-6mm at the C1-C2 joint (the atlas-axis) when I bent sideways, from ear to ear. This finding has led to a flurry of varying opinions; some medical experts express that it's a significant issue that warrants further investigation, while others reassure me that it is harmless. Conflicted and uncertain about the next steps, I continue to suffer from headaches. Unfortunately, I have yet to convince any of my doctors, including my spine specialist, to consult a neuroradiologist for a more definitive assessment. The ambiguity around this finding has left me anxious and in search of clarity about my condition.
Dizzy and Concerned: Experiencing Dark Vomiting
It’s currently 4:15 AM for me, but earlier around 4 PM, I began feeling lightheaded, sneezing, and shivering when the fan's breeze touched my skin. I wanted to share my recent experience that has left me quite anxious. Back in February to March, I was hospitalized for acute gastroenteritis. Luckily, I have since recovered, but now, in September, I've encountered a troubling situation. I vomited a dark brown and black mixture, which has raised my alarm. While my bowel movements appear normal, I've gone through four separate episodes of vomiting. Each session involved 3 to 4 bouts. In the initial episodes, the vomit was predominantly greenish-yellow, but by the third occurrence, it shifted to a darker hue with sticky black elements. It was during the fourth episode that I really started to worry and conducted some research. I came across information suggesting that this could indicate internal bleeding, which has left me quite distressed. I’m seeking clarity and reassurance about these symptoms.
Living with Chronic Pain After Dental Implant Issues: A 17-Month Struggle
Approximately five years ago, I underwent the placement of two dental implants, skipping the recommended CT scan beforehand. This oversight resulted in dire complications: a perforation of the lingual cortical plate, subsequent infections, and swelling in my mandibular glands. Following a series of treatments, which included the removal of the implants and curettage, I now endure persistent and excruciating pain that has lasted for an astonishing 17 months. My diagnosis is mandibular osteomyelitis. Despite my best efforts to alleviate this pain, including the use of antibiotics, various pain relief medications, and even morphine coupled with medical cannabis, I have found no significant reprieve. The discomfort has been incessant and intolerable since the implants were inserted. I am reaching out for insights, shared experiences, or advice from anyone who has faced a similar situation. What strategies did you employ? Were there any particular methods or treatments that aided your recovery or alleviated your pain? I am a 53-year-old woman weighing 50 kg.
Concern Over High Hematocrit After Insect Bite
Subject: Female, Age 50 Location: United States Several months ago, I experienced an insect bite that has since left me feeling quite unwell. I am currently awaiting the results of a panel that tests for tick and insect-related illnesses. Recently, I received some preliminary findings indicating that my hematocrit level is at 45.9, which falls within the elevated spectrum. In contrast, my metabolic panel, complete blood count (CBC), and C-reactive protein levels are all within normal limits. Given that my hematocrit was recorded at a normal value of 43.8 just three weeks ago, should I be worried about this increase?
