What's Causing the Blood Under My Nails?

8/8/2025, 5:10:25 PMMale25-34

Greetings everyone! I’m a 23-year-old female, and I've recently encountered an unusual issue where I notice blood appearing beneath my nails, seemingly without any warning. Notably, this condition seems to be more pronounced on the nails of my left hand. This situation began approximately three months ago, prompting me to visit my general practitioner for a consultation. Following that, I underwent a blood test, which fortunately returned normal results. The blood tends to disappear for a few days at a time before reappearing, and although it’s not accompanied by any pain, it’s quite alarming to witness. My medical history shows no prior diagnoses, and I'm not currently on any medication.

It sounds concerning to see blood under your nails, especially since it appears intermittently. Given that you have consulted a general practitioner and had normal blood test results, it’s good to know that major issues have been ruled out. This symptom can occur due to several reasons, such as minor trauma, nail bed issues, or even certain skin conditions.

Explanation:

Blood under the nails can sometimes result from:

  • Minor Trauma: Small injuries or repeated friction from activities like typing or using tools can cause blood vessels in the nail bed to break, leading to bruising.
  • Nail Bed Conditions: Conditions like subungual hematomas (blood collection under the nail) can occur without significant pain.
  • Skin Conditions: Certain dermatological issues can cause changes in the nails or surrounding skin.

Next Steps:

  1. Monitor Symptoms: Keep a journal of when the blood appears and disappears. Note any activities or changes that coincide with these episodes.
  2. Protect Your Nails: If you engage in activities that could cause trauma (e.g., sports, manual work), consider using nail guards or protective gloves.
  3. Limit Moisture Exposure: Keep your hands dry and consider using a moisturizer to improve nail integrity if there’s any dryness.
  4. Observe for Additional Symptoms: If you notice any changes such as pain, swelling, or changes in nail color/texture, take note of these as they could provide important clues.
  5. Follow Up with Your Doctor: If symptoms persist or worsen, especially with new symptoms, schedule another appointment to discuss your ongoing concerns. Consistent follow-up can help in monitoring any changes that might need more investigation.

It’s understandable to feel anxious about this unusual symptom, but being proactive about monitoring it is a great step forward. Let me know if you have any other questions or concerns!

Understanding Patent Ductus Arteriosus

I recently learned that my 7-year-old daughter has a minor patent ductus arteriosus (PDA). She underwent an echocardiogram due to our family's background of bicuspid heart valves, which I, along with my father and brother, also have. While her heart valves appear healthy, the echocardiogram did reveal this small PDA, as indicated in the report I received. Although I anticipate hearing from the doctor by Monday, that means I have two days to ponder this situation and feel anxious about it. I’m curious—do all PDAs require surgical intervention? Considering her age, it’s unlikely that it will close spontaneously. If anyone has any experiences or knowledge regarding this condition, I would greatly appreciate your input! Thank you!

Should You Discuss Your Own Research on Test Results with Your Doctor?

I recently underwent an echocardiogram, and while awaiting my cardiologist's call, I took it upon myself to look up what constitutes normal values and compare them with my own results. When she eventually reached out, she highlighted two abnormalities in my readings; however, one noticeable irregularity was not mentioned in our conversation. This has left me pondering whether I should address this overlooked abnormal result at our upcoming meeting, or if it might be best to refrain from mentioning it, considering her expertise in this area. I have complete confidence in her assessments, yet I find myself feeling a bit anxious about this situation.

Mild Symptoms After a Head Injury: Should I Consult My Doctor?

Greetings and thanks for taking the time to read my post. * I am a 37-year-old woman. * My weight is approximately 165 pounds, and I stand 5 feet 9 inches tall. * Current medications include daily Symbicort for asthma and melatonin on rare occasions (about once a month) to assist with sleep. * I also smoke marijuana a few times each week, but have refrained from using it since my injury to avoid hindering my recovery. **Background:** * One week ago, on January 31, I had an accident where I tripped and struck my head against a doorframe late at night. Following this incident, I exhibited signs of confusion and slurred speech, prompting my partner to take me to the emergency room. There, a head CT scan was done, which the physician reported as normal with no significant issues. A nurse also checked for signs of a stroke, which were negative. * I received advice to limit my activities and to reduce exertion if any symptoms arose. I adhered to these recommendations, spending the past week primarily resting, eating, and sleeping. * I suspect I sustained a concussion, although I do not recall any doctor directly informing me of that diagnosis. * Curiously, I do not remember the moment I hit my head; I thought I recalled tripping, but I believed I caught myself before the fall, even though I developed a large bump on my head shortly afterward, leading to two black eyes a day or so later. At the hospital, I didn’t have any alarming symptoms upon my discharge—the initial confusion and slurred speech had resolved within hours. During this week, I have been cautious and have largely avoided any strenuous activity. Notably, I have experienced absolutely no headaches or confusion, which would raise concerns about a concussion. On Thursday, five days after my injury, I felt sufficiently well to meet a friend for lunch, but I noticed some dizziness at the café and struggled slightly to engage in conversation. The following day, which marked six days post-injury, I attended a work conference featuring speakers and presentations. However, while navigating a crowd, I felt quite dizzy and experienced mild nausea, leading me to leave early and head home. I do have a slight pain in my neck—it’s mild, around 1 out of 10 in intensity. My range of motion is unaffected, though it feels a bit tender. This discomfort did not exist during my hospital visit but started a few days later, possibly due to an awkward sleeping position rather than being related to my head injury. **My inquiry is this:** Are milder symptoms one week after a head trauma common, or should I consider making an appointment with my primary care doctor regarding my condition? If a slower recovery is typical and I simply need to allow more time for healing, I would prefer not to occupy a scheduling slot at the clinic. Conversely, I want to avoid potential complications—or post-concussion syndrome—and seek help if necessary. I genuinely appreciate any insights you can provide.

What Could These White Fibrous Strands in My Wound Be?

Age: 30, Weight: 140 lbs, Height: 5'6, Racial Background: White. About seven days ago, I accidentally cut myself while shaving. I've visited a medical professional and am currently taking antibiotics. However, I'm curious about these strange white, fiber-like materials appearing in my wound. The nurse indicated that the pus I have might be green, but I don’t see it; I thought it was merely a scab. How serious does my infection seem? It’s tender and has moments where it throb, causing me to limp occasionally.

Accidental Eye Injury from a Needle

At 16 years old, I experienced an incident while attempting to extract a small blackhead from my nose using a needle. Unfortunately, I accidentally jabbed the needle into my eye. Initially, it seemed like the needle didn’t penetrate deeply, but the pain was considerable at the moment, and while it has since diminished, I still feel some discomfort. My eye also has an itchy sensation. I am concerned about whether injuries of this nature can lead to lasting damage or if they typically heal over time. Additionally, I would like to know if there are specific symptoms I should monitor as I recover.
