Am I Overreacting to a Hydraulic Injury?
In my situation, as a 31-year-old male weighing 200 pounds, I accidentally pricked my thumb on a metallic spring that had a slight coating of hydraulic oil. The contamination was minimal, likely just a thin layer rather than any significant amount. Unfortunately, it penetrated my nitrile glove and made contact with my skin. Upon realizing this, I promptly removed the glove and applied pressure to my thumb to encourage the blood to flow and cleanse the area. I then washed my thumb thoroughly under running water for several minutes, followed by cleansing it with soap. Now, around three hours have elapsed, and my thumb feels mostly normal. I’m not experiencing any numbness, swelling, or tingling sensations, with only a slight discomfort when the wound is exposed to water, which I’d rate as a 2 out of 10 in intensity. I want to confirm whether I’m being overly cautious and if it’s safe to treat this as a typical minor injury. I often find myself feeling anxious about injuries and tend to overthink situations like this, especially considering the presence of oil. For context, I received my last tetanus vaccine in early 2020, making it well within the five-year window. I’ve noted that there hasn’t been any significant change in my thumb’s appearance roughly three hours post-injury.

You are taking a thoughtful approach to your situation, and it’s understandable to feel anxious about injuries involving substances like hydraulic oil. Here's what you need to know:
Key Points:
- Your reaction to the injury is natural, but based on your description, it sounds like you handled it well.
- Minimal exposure and thorough cleaning are critical in preventing infection or complications.
- Your symptoms currently suggest that serious issues are unlikely.
Explanation:
Hydraulic oil can contain various additives, but since the contact was minimal and you took prompt action by washing the area, the risk of serious harm is significantly reduced. The slight discomfort you're experiencing is common with any minor skin injury but should improve with time. Since you’re without any concerning symptoms such as swelling, redness, or worsening pain, this adds to the reassurance that your injury is minor.
Next Steps:
-
Continue Monitoring: Keep an eye on your thumb over the next 24-48 hours for any signs of infection (increased redness, swelling, or pus).
-
Keep it Clean: Maintain cleanliness by washing your thumb gently with soap and water before applying any ointments if needed. You can apply a thin layer of antibiotic ointment (like Neosporin) to aid healing if there are no signs of allergic reaction.
-
Protect the Area: If the area is tender, consider covering it with a bandage to keep it clean and reduce irritation from exposure to water.
-
Manage Anxiety: If you find that you're feeling anxious about the injury, it may help to practice breathing exercises or mindfulness techniques to reduce stress. Staying informed and monitoring without excessive worry is beneficial.
-
Follow Up if Needed: If you notice any worsening symptoms or develop new ones, don’t hesitate to reach out for further assessment.
Your caution is completely valid, but it looks like you're on the right track. Take care of yourself!

Should I Worry About This Blister?
I’m 24 years old and have developed a blister on my ankle. Initially, when it was starting to form, the area around it was inflamed, prompting me to apply some antibiotic cream. However, after a day, the redness has subsided, yet the blister itself has enlarged and taken on a yellow hue. Fortunately, there are no additional signs indicating an infection. My treatment approach thus far has been quite simple: I periodically apply antibiotic cream but otherwise avoid touching it. Should I be worried about this blister, or is it best to just let it be?

38-Year-Old Male Seeking Clarity After 9 Years of Health Struggles
Hello everyone, I’ll aim to be succinct and straightforward. **About Me:** I am a 38-year-old male, who avoids smoking, alcohol, and drugs. For a significant part of my life, I dealt with obesity, but in the period from 2012 to 2015, I achieved a personal best by dropping from 220 pounds to 145. Unfortunately, I’ve regained that weight due to limitations preventing me from staying active and engaging in desired activities. My blood pressure has consistently hovered near the hypertension threshold. Anxiety wasn’t part of my history until the onset of my health issues. **Health Problems:** The emergence of my symptoms began around 2016. Initially, they were mild but progressively worsened over a couple of months. I experience severe fatigue, occasional bouts of dizziness, nausea, cognitive clouding, headaches with migraines, and neck pain. Shortly after these symptoms manifested, I noticed blood in my stool for about a week, alongside developing heat intolerance. At times, I feel faint or as if I lack sufficient blood flow or oxygen to my head, similar to the sensation of being tipsy despite not consuming alcohol. Engaging in cardio-intensive activities exacerbates these issues significantly. **Medical Journey:** I have sought help from numerous healthcare professionals without uncovering any explanations for my symptoms: - Consulted five primary care physicians, undergoing extensive blood tests. - Visited three ENT specialists, including several sinus CT scans. - Met with three cardiology experts, who performed EKGs, stress tests, and heart ultrasounds. - Consulted an endocrinologist who dismissed my concerns quickly. - Spoke with a sleep specialist who diagnosed me with mild hypersomnia. - Had a brain MRI with a neurologist. - Had an upper GI assessment with a gastroenterologist. - Made multiple trips to the ER, seeing 6-8 different doctors. - Attended therapy sessions to help cope with these prolonged issues. - Continued regular visits with a chiropractor, who I had been seeing for five years prior. **Additional Remarks:** - Residing on the east coast of the US, an area known for Lyme disease, I spend a lot of time outdoors. I had to advocate for Lyme testing, which showed three out of ten indicators, but I was informed that this result is considered negative. - One ER physician suggested checking my kidneys, but his recommendation was never entered into the system, leaving me unable to follow through. - Three years ago, desperate for relief, I started Cymbalta as advised by my primary care physician, but it hasn’t altered my symptoms. - My wisdom teeth were extracted a year before my health issues began. - Lying down in any position seems to alleviate my symptoms; consequently, I frequently rest in this manner during my free time. - Three years ago, my vitamin D levels were low enough to require a prescription, despite taking daily supplements. - An ER doctor once noted scarring on my left lung, asking if I was recently ill, which I wasn’t beyond my ongoing symptoms. He suggested following up with my PCP, who showed little concern and offered but did not carry out follow-up X-rays. - I meticulously tracked my diet and blood sugar levels for over a month, utilizing finger pricks and a continuous glucose monitor. I found that my symptoms tended to flare up when my levels dropped to around 70 or lower. However, my endocrinologist insisted that those levels fall within a normal range and are not to blame. This summarizes my current situation. I’ll add any additional thoughts as they arise.

Is This Blood?
I observed my 17-month-old son after he filled up on water and subsequently vomited. Within the vomit, I spotted dark brown to maroon streaks that resembled meaty substances.

He isn’t taking any medication, and for dinner, he had fish accompanied by spinach and quinoa.
