Concern About Blood in Semen
Greetings. I am a male, aged 18, and I've recently encountered a troubling issue. Approximately a month ago, I discovered blood present in my semen. Since noticing this change, I have ejaculated around three times, including instances of nocturnal emissions, and on each occasion, the semen appeared predominantly red. I am perplexed as to what might be the underlying cause of this. There have been no accompanying symptoms such as discomfort during urination or ejaculation, nor have I observed any blood in my urine—only the semen seems to be affected. Given my uncertainty and concern, could you please provide insight into what might be causing this?

It's understandable to feel concerned about noticing blood in your semen, as it can be alarming. This condition, known as hematospermia, can have various causes, and many are benign, especially in young males like yourself.
Possible Causes
- Infection: Sometimes, an infection in the reproductive system can cause blood to appear in semen, even without other symptoms.
- Inflammation: Conditions like prostatitis (inflammation of the prostate) may lead to blood in the semen.
- Trauma: Any recent injury to the genitals could result in bleeding during ejaculation.
- Benign growths: Cysts or varicoceles (enlarged veins in the scrotum) can also result in similar symptoms.
Next Steps
- Monitor Symptoms: Keep track of any changes, such as the frequency of blood in your semen, along with any new symptoms like pain or changes in urination.
- Stay Hydrated: Ensure you drink plenty of water; hydration can help support overall health.
- Avoid Irritants: Refrain from any aggressive sexual activity or manipulation that could exacerbate sensitivity or irritation.
- Seek Professional Guidance: If the bleeding continues or worsens, it would be wise to consult a healthcare provider for specific evaluation and possible testing. This can help rule out any serious conditions and provide peace of mind.
While it often resolves on its own, keeping an eye on your symptoms and seeking appropriate advice when necessary can ensure your well-being. Please take care of yourself, and don’t hesitate to reach out for help if needed.

What Could This Mark on My Leg Indicate?
Age: 44 Height: 5’0” Weight: 185 lbs (currently addressing this) Health Conditions: Hypertension (managed with metoprolol), elevated cholesterol (kept in check with Lipitor), food allergies, acid reflux (treated with pantoprazole), anxiety and depression (on sertraline) Location: NC, USA I noticed an unusual mark on my leg on Monday, situated close to my ankle along the shin area. I’m certain it wasn’t there the previous day, as I have a snapshot from Sunday displaying my leg. On Sunday evening, I accidentally dropped a pan filled with salmon, which caused some splatters to hit my other leg. While I felt no impact on this particular leg, the other one appears normal. When I saw this mark on Monday, my first thought was that it might be a burn due to the incident. However, it doesn’t resemble a burn since it feels different and is raised rather than showing any signs of damaged skin. It hasn't caused me pain, but it did itch quite a bit on Monday night. The itching has subsided somewhat, yet I can still feel some irritation, especially when my clothing rubs against it. My main concern is whether this could be a bullseye rash from a tick bite. I haven't detected any ticks on myself, but it is still a possibility. Additionally, I have a few other insect bites, including some from Sunday night, but none exhibit characteristics similar to this particular mark. I'm seriously considering having it examined due to my concerns, but I'd appreciate any insights from others.
Seeking Guidance on Health Concerns for 12-Year-Old Girl
Greetings everyone, I am reaching out for some expert advice regarding a 12-year-old girl who has been facing several alarming health challenges over the past few months, and unfortunately, the local physicians have not been able to provide adequate help. After she took ibuprofen (Ardil), she experienced two instances of severe cold sweating and a drastic drop in body temperature, reaching as low as 34°C. Both episodes occurred within an hour of taking the medication; the latest one happened today. During these incidents, she appeared very pale, was excessively sweaty, and had noticeably cold skin, necessitating immediate warming. Additional health issues she is contending with include: - An extreme lack of appetite, resulting in nearly no food intake - Rapid weight loss occurring over the last several weeks - Ongoing stomach pain and a prior diagnosis of gastric inflammation - Significant sweating that is particularly pronounced at night or following minimal physical exertion - Occasional burning sensation while urinating, noted once in the previous week - Deteriorating dental health and a delay in the eruption of her upper lateral incisors - Persistent fatigue and weakness Though her doctors have prescribed various medications, they have not conducted thorough diagnostic tests like lab work or imaging studies. According to her mother, while the initial blood tests came back "normal," no further examinations (such as for Helicobacter pylori or potential endocrine or autoimmune disorders) have been pursued. Is it possible that she might be experiencing an allergic or systemic reaction to the ibuprofen? Or might there be a more serious underlying condition related to metabolism, gastrointestinal health, or endocrine function that has yet to be identified? Any recommendations regarding appropriate tests or specialist consultations would be immensely helpful. Thank you for your assistance.
Concerns Regarding My Daughter's Health
I’d like to share some background about my daughter, who is 1.5 years old, weighs around 25 pounds, and as far as I can tell, isn’t of smoking age. Recently, she hasn’t shown any signs of illness. However, we've noticed that she’s been sleeping a lot more than usual, feeling fatigued with ease, and has been prone to bruising. Additionally, she has experienced some bouts of vomiting sporadically over the last three months. We visited the pediatrician, and while all her blood tests have come back normal, except for certain results that I’ll outline shortly, the doctor has not yet reviewed these findings. I’m trying to advocate for her well-being without being overly assertive, especially if there’s nothing serious going on. Highlighted as Abnormal in her lab results: - MPV: 8.6 (slightly elevated) - Neutrophils: 16.2% - Lymphocytes: 76.3% - Eosinophils: 0.3% - Absolute Lymphocytes: 8.5 - Absolute Immature Granulocytes: 0.09 - IG: 0.80 I would appreciate any insights or thoughts you may have on her condition.

Injury While Cooking—Should I Be Concerned About Tetanus?
Age: 26 Gender: Male While preparing vegetables, I ended up injuring my finger quite badly; there's a sizable flap of skin, but the bleeding has largely ceased now. The accident happened while I was slicing celery, and my knife had also been used for cutting an onion earlier. Should I be concerned about the risk of tetanus? I understand that tetanus spores are often present in soil, which suggests the knife might not be a source of concern. However, I’m apprehensive about the celery and onion potentially carrying the bacteria. It’s been more than a decade since my last booster shot. I realize that I need to get it updated, but is this a situation where I should seek immediate attention today, or can it wait until my routine checkup in six months?
