Concerns About Blood in Stool: Is It Possible My Samples Were Mixed Up?
Hello everyone, For the past four to five months, I've been dealing with chronic constipation. On my doctor's advice, I underwent blood tests and a fecal occult blood test (FOBT). The results from the FOBT—which consisted of three samples taken on different days—all came back positive, with values nearly double the accepted maximum. Consequently, I consulted a proctologist who ruled out hemorrhoids and anal fissures. Following their recommendations, I had a colonoscopy done yesterday, which came back clear. I was relieved to find out that everything is in excellent condition; I'm a 28-year-old male and had been anxious about a potential colon cancer diagnosis, primarily due to family history—both my maternal grandfather and great-grandmother had it, while my mother faced pancreatic issues. I’m incredibly relieved! However, the proctologist has now recommended that I undergo a gastroscopy as well. I haven't yet discussed this with my GP, but during my hospital visit, a family friend who assisted with my examination also inquired if I wanted to schedule a gastroscopy. To be honest, I would prefer to avoid it if possible. This leads me to wonder about the likelihood of my samples being swapped with someone else's. I'd much rather repeat the FOBT than proceed with a gastroscopy. What would you advise? How likely is it that the FOBT results aren't actually mine? If I were to go ahead with the gastroscopy, what are the chances they would find anything problematic at this time? Are there any additional tests you would recommend? Here are some further details that may be relevant: - I reside in the EU. - My blood test results were largely normal, though they indicated low levels of cobalamin (B12) at 134 pg/mL (the normal range is 180-914 pg/mL). Both my hemoglobin (173 g/L; normal range 120-160 g/L) and erythrocytes (5.80; normal range 4.00-5.50) were slightly elevated. - The blood samples do belong to me, as my GP had me repeat the tests after two weeks and the results were consistent. - I experience no abdominal pain or gastric reflux and have never had any gastrointestinal issues. - Aside from taking Neuraben—recently prescribed by my GP for the low B12 levels—I am not currently on any medication. - I lead a relatively sedentary lifestyle, smoke about 5 to 8 cigarettes a week, and consume beer around 5 to 7 times a week. Thank you sincerely for reading through all this!

It's understandable to feel anxious about your test results and the need for further evaluation. You've already taken significant steps by undergoing preliminary tests, and it's important to address your concerns regarding the next steps clearly.
Main Points:
- Errors in sample mix-up are rare, especially with multiple tests done on different days, and your results are consistent.
- A gastroscopy can provide important information, particularly regarding your gastrointestinal health, and it may be warranted given your history.
- Monitoring your B12 levels and lifestyle choices can also be beneficial for your overall health.
Explanation:
- While it's natural to wonder about the accuracy of your tests, the chance of a sample mix-up is quite low, particularly since your doctor had you repeat the tests and both results aligned. This consistency suggests that the FOBT results genuinely reflect your health conditions.
- Proctologists often recommend follow-up procedures like gastroscopy to check for issues in the upper gastrointestinal (GI) tract, especially given your family history with cancers. This procedure is generally safe and can help assess if there are any issues higher up in the digestive system.
- Since your colonoscopy was clear, chances of finding anything concerning during a gastroscopy are generally lower, but it can still reveal underlying issues such as gastritis or ulcers.
Next Steps:
-
Consider the Gastroscopy: Discuss your concerns and ask if the pros of the gastroscopy outweigh the cons in your case. Ask about sedation options and recovery time so you feel more comfortable with the procedure.
-
Lifestyle Adjustments: While awaiting your next steps, consider enhancing your diet to include more vitamin B12-rich foods (like meats, dairy, and eggs) and reflect on reducing smoking and alcohol consumption. These can improve your digestive health and overall wellbeing.
-
Symptom Monitoring: Keep a journal of any symptoms you may experience (like changes in bowel habits, appetite, etc.) that might provide valuable information for your healthcare providers.
-
Follow-up on B12 Levels: Since your levels were low, staying in touch with your GP regarding your B12 treatment and any necessary adjustments can further support your health.
Completing the gastroscopy could provide you with peace of mind, but ensure you feel informed and comfortable with your decision. Remember, taking proactive steps in communication with your healthcare team can guide you in the right direction. If you have more specific questions about procedures or your health, feel free to reach out!

17-Year-Old Female Experiencing Chronic Acne Scarring on Back and Arms Despite Prescription Remedies
Age: 17 Gender: Female Country of residence: United Kingdom Skin type: Dark / Black Medical background: No significant health issues Medications: Previously utilized azelaic acid and benzoyl peroxide Timeframe: Many months to years following acne resolution Greetings, I am a 17-year-old girl dealing with long-lasting scars on my back and upper arms from acne, which have not improved even after following prescribed treatments. In the past, I experienced acne primarily on my upper back, shoulders, and arms. While the active breakouts have largely ceased, I am left with noticeable dark spots and irregular skin texture. The scars I have include: • Dark brown hyperpigmentation • Certain areas appear slightly sunken • Uneven or coarse surface • No raised or keloid scars present My GP prescribed azelaic acid and benzoyl peroxide, which I applied regularly. Unfortunately, the azelaic acid did not significantly lighten the scars and seemed inadequate for the pigmentation level. Although benzoyl peroxide was effective against my active acne, it did not enhance the appearance of the scarring. The marks have been present for a considerable time and are quite stark against my skin tone. I do my best to avoid picking at my skin and maintain proper hygiene, yet the scars aren’t diminishing on their own, which is negatively impacting my self-esteem—especially when I wear sleeveless or backless outfits. Currently, I'm exploring the possibility of using retinoids like adapalene or tretinoin. However, I’m uncertain if these would be suitable or effective for treating scarring on my back and arms, particularly with my darker skin type. I would like guidance on the following questions: • Does this seem to be primarily post-inflammatory hyperpigmentation, atrophic acne scars, or possibly a combination of both? • Is azelaic acid effective for this type of scarring, or are more potent treatments generally required? • Are topical retinoids such as adapalene or tretinoin advisable for this sort of scarring? • What treatments are typically recommended for acne scars on the back and arms in individuals with darker skin tones? • Should I insist on a referral to a dermatologist, or is it better to attempt specific topical therapies first? Any insights or recommendations you could offer would be greatly appreciated.
Persistent Itching and Burning Around Neck and Scalp - Should I Keep Using Cephalexin?
Greetings, I’m a 35-year-old female. I recently developed a rash that began on the back of my neck and subsequently spread to my ears. After consulting with my physician, I was prescribed ketoconazole shampoo to address a suspected fungal rash. Despite using it diligently for four days, the condition actually aggravated, affecting my ears, the back of my neck, and my scalp more significantly. Seeking further assistance, I visited an urgent care facility where the medical staff suggested that I might be experiencing bacterial folliculitis. As a result, they prescribed cephalexin, which I am to take at a dosage of 500mg three times daily for a week. I took my first dose yesterday, yet the intense itching and burning sensations persist without improvement. Is it advisable for me to continue the medication? How long does it typically take to see improvement? Is it common to experience these symptoms alongside bacterial folliculitis? I appreciate your time and any guidance you can provide on this matter!
Concerns About Hearing Loss After Extended Earphone Use
For the past two and a half years, I have primarily relied on in-ear earphones, with the right one typically experiencing less usage—mostly for short videos or brief instances. Recently, during a singing session, I noticed something unusual. I covered one ear to monitor my pitch, and I was surprised to find that my hearing felt unclear and somewhat muffled. This was an experience I hadn’t recognized before. After conducting a few tests by alternately covering each ear, I discovered that my left ear can hear clearly and accurately, while my right ear perceives sounds as muffled, as if there’s a barrier in front of the speaker. I’m seeking advice as a 17-year-old student from Pune, India, with financial constraints that prevent me from adding stress to my parents. I’m deeply concerned whether this issue could be permanent, and if there’s any possibility of recovery. Although I can still hear sounds from my right ear when they are very close, I am unsure of the next steps. I have made the decision to discontinue using earphones starting today, but I’m wondering what additional measures I should take. Would it be advisable to pursue an audiometry test or consult an audiologist for a professional evaluation?
Experiencing Headaches and Vision Changes on One Side
Hello, I'm an 18-year-old female, and I've been on a 15mg dose of Isotretinoin for my acne treatment for about a month now. Recently, I've been feeling under the weather, dealing with a viral infection that resembles cold or flu symptoms. I've got the usual problems like nasal congestion and a throat that hurts, but I've also noticed some joint discomfort, a sense of mental cloudiness, and an unsettling change in my vision, making it appear distorted as if seen through a low-resolution lens. Additionally, when I change my position from sitting to standing, there's an intense throbbing sensation on the right side of my head, accompanied by a momentary blackout in my right eye. I must admit, my nutritional intake has not been great lately due to feeling fatigued from the cold, and this has been accompanied by headaches and a notable darkening of my vision when I stand, which is something I've never before experienced just on one side until now. I tend to get quite anxious about my health, so I'm reaching out to see if anyone else has encountered similar symptoms with a cold, or if this could be associated with the Isotretinoin I'm taking? Any insights or advice would be greatly appreciated, thank you!
