Concerns About Arm Bruise with Unusual Dent
A 34-year-old woman, who has a normal body mass index, does not smoke, and is generally in good health without any medications, is seeking advice regarding a recent arm injury. Two days prior, she accidentally pinched her arm while closing a stroller, initially attributing the resulting discoloration to a regular bruise. Immediately after the incident, the bruised area turned pale, causing her some concern regarding the circulation in her arm, although she dismissed it at that moment. Now, as time has passed, a peculiar crescent-shaped indentation has surfaced adjacent to the original bruise. This formation appears to be unrelated to any intensity of pressure or additional trauma—it feels like an actual depression in the skin, with the center of the bruise exhibiting a numb sensation. What might be the cause of this change? Is this something that warrants concern?

It's understandable to be concerned about the changes you're noticing on your arm after the injury. The combination of a bruise, an indentation, and numbness can be worrying, so it's good that you're seeking clarification.
Main Points:
- Possible Causes: The crescent-shaped indentation and numbness may relate to tissue healing or minor nerve involvement due to the initial trauma.
- Monitoring Symptoms: While it could resolve naturally, observing changes in your symptoms is crucial.
Explanation:
When you experience a bruise from an injury, there's likely damage to blood vessels, which can lead to discoloration and swelling. The unusual indentation might suggest that the surrounding tissue has become slightly compressed or that there's been a mild disruption in skin or muscle structure. Numbness can occur if a nerve was temporarily affected by the injury or if swelling around the bruise has increased pressure on nearby nerves.
Next Steps:
- Observe Changes: Keep a close eye on the bruise. Note if the indentation improves, worsens, or if numbness spreads.
- Gentle Care: Apply a cold pack to the area for 10-15 minutes several times a day to reduce any potential swelling. Avoid applying pressure to the area.
- Limit Activity: Try to avoid using your arm heavily until you're more certain of what’s happening to prevent aggravating any possible injury.
- Monitor for Symptoms: If you notice increased pain, swelling, or if the numbness spreads, or if you have any other alarming symptoms (like changes in mobility or severe color changes), take those seriously.
When to Seek Help:
If the indentation persists beyond a week without improvement, or if you have new symptoms like pain or ongoing numbness, it would be wise to consult a healthcare professional for further evaluation. Your health is important, and getting reassurance or treatment can help you feel better. Let me know if you have additional questions or need more information!

Injury from Rusty Staple: Do I Need a Tetanus Booster?
I’m a 37-year-old woman weighing 125 pounds. Earlier today at my workplace, I accidentally punctured my index finger on a rusty staple. Although the wound was relatively shallow, it bled quite a bit. I washed the area right away, treated it with hydrogen peroxide, washed it again, and then covered it with a bandage. The rust on the staple was likely due to contact with my pet's urine. It has been ages since I last received a tetanus booster, probably around my high school years in the early 2000s. Should I consider getting a booster shot, or given how minor the injury is, should I be fine without it?

Navigating Contradictory Medical Advice
Is it typical for healthcare professionals to hold such varying opinions regarding my fracture? I am a 25-year-old woman, standing 170 cm tall and weighing approximately 85 kg. My only other medical condition is asthma, which I manage with an inhaler on an as-needed basis, rather than daily. On July 1st, I experienced an avulsion fracture of my lateral malleolus while at work, which necessitated wearing an open cast for a duration of ten days after a trip to the emergency department. During my ER visit, I was informed that a follow-up X-ray would be conducted to determine the subsequent steps in my treatment. Throughout the ten days of immobilization, my pain significantly decreased, to the point where I found myself walking on the cast without crutches, albeit doing limited, controlled movements. I opted against taking any pain medication, aside from my contraceptive and administered clexane injections, affirming that I was genuinely pain-free during this period. However, during my appointment to remove the open cast, there was no new imaging performed. Instead, the doctor proposed a further ten days in a closed cast, without considering how I was coping, whether I was able to walk, or how much pain I might be in. It struck me that the physician seemed to be applying a universal protocol for all patients with similar fractures, despite her specialty in foot and ankle injuries. Consequently, I declined the closed cast, reasoning that additional immobilization would be detrimental rather than beneficial, and I opted for a brace instead. The medical staff reacted dramatically to my decision, cautioning that I should not return if complications arose. Ultimately, however, I know my body and experience best. I've since begun attending prescribed physiotherapy sessions, where the therapist echoes my sentiments regarding the benefits of avoiding a cast. In fact, he has even permitted me to move about without a brace on flat surfaces, though I plan to wear it when I return to work on Monday for safety reasons. This whole experience has left me questioning whom to trust in the future, should I find myself in a similar situation again. Why is there such inconsistency between the hospital's recommendations and those of the physiotherapist? While the hospital doctor suggested I would still be confined to a cast on Monday, my physiotherapist believes I can resume work without any delays—a striking contrast that adds to my confusion regarding the best course of action for recovery.
Is There a Risk of HPV Transmission from Sharing a Joint?
Hello everyone, I’ve been feeling quite unsettled regarding a concern and would greatly value some truthful and well-informed feedback. My question pertains to the transmission of HPV, specifically in the context of sharing marijuana joints with someone who has genital HPV. While I can't confirm anything about oral HPV in this scenario (she has been diagnosed with cervical cancer), we haven’t engaged in kissing or sexual activity — simply shared joints together. Does this present any credible risk of contracting oral HPV from this action? I understand that HPV is primarily spread through sexual activity. However, I've come across various opinions regarding whether saliva or sharing items that have contact with the mouth might play a role in transmission. If the joint were to contain saliva during our use, could that serve as a pathway for the virus to spread? Prior to learning about the HPV diagnosis, I had shared joints with this individual on several occasions, and now I find myself quite anxious about the situation. Should I consider getting tested, or is it better to refrain from overthinking this matter? I appreciate any thoughtful and scientifically grounded responses you might have.
White Bump on Foot
A 39-year-old individual, standing 5’9 and weighing 140 pounds, reports experiencing a small white bump on the front part of the arch of his left foot. Currently, he is not taking any medications nor managing any medical issues. This nodule may have resulted from stepping on a piece of wood that penetrated the skin approximately two weeks prior. Inspection reveals there is no visible damage to the skin's surface; it appears to be entirely beneath the outer layer. The growth is not sensitive when touched lightly, however, it does cause pain when pressure is applied directly onto it. What could be the underlying cause of this issue? Would it be advisable to use a sanitized needle to attempt to relieve the pressure by piercing the bump?
