Concern Over Dad's Bug Bite Reaction
Recently, my father, who is 63, scratched a bug bite on his leg, and I’ve noticed that the area has become swollen, inflamed, and painful. This incident occurred during nighttime, and he isn’t certain if the bite was from a tick. I’m wondering if the redness resembles the symptoms associated with Lyme disease or if it could indicate something that requires medical attention.

It sounds concerning that your father's bug bite has become swollen, inflamed, and painful. These symptoms could indicate an allergic reaction, infection, or, in some cases, a tick bite, especially since you're worried about Lyme disease. It's important to assess the situation carefully.
Explanation:
When a bug bite becomes red, swollen, and painful, it may be due to several reasons:
- Allergic Reaction: The skin can react to insect venom or foreign substances, often leading to inflammation.
- Infection: Scratching the bite can introduce bacteria, causing an infection that leads to swelling and pain.
- Tick Bite: If the bite indeed came from a tick, signs of Lyme disease could include a rash resembling a “bull's-eye” and flu-like symptoms, which typically appear weeks after the bite.
Considering your father’s age and the changing nature of the bite, it's good to be cautious.
Actionable Next Steps:
- Monitor Symptoms: Keep an eye on the bite area for changes. Take note of any increasing redness, swelling, warmth, or if he develops a fever or chills.
- Clean the Area: Gently wash the bite site with soap and water to reduce the risk of infection.
- Reduce Itching and Swelling: Consider applying a cold compress to the area or using over-the-counter antihistamines (like Benadryl) and hydrocortisone cream to alleviate itching and swelling. Follow the dosing instructions on the package.
- Track Additional Symptoms: Watch for symptoms of Lyme disease, such as fever, fatigue, headache, or muscle pain. If a circular rash forms or his overall condition worsens, this may require immediate attention.
While it's comforting to focus on home care, be prepared to seek further medical attention if:
- His symptoms don't improve in a few days.
- He experiences increasing pain or fever.
- Any signs consistent with Lyme disease develop.
Please keep close tabs on your father, and I'm here if you need more guidance!

Unexplained Bruising After Walking
Age 29, female, weighing 150 pounds, standing 5 feet 10 inches tall, non-smoker, drinks socially perhaps twice a year, currently taking only d-mannose and cranberry supplements, along with occasional digestive enzymes with meals. Recently, I have been noticing unexpected bruises on my legs. The largest one measured about 3.5 inches, while the others have been smaller, appearing in shades ranging from blue to purple or green, often in solid colors. I typically have no more than four visible bruises at one time. During the two weeks I was stuck at home and unable to walk due to having company, these bruises healed up completely. However, just last week, after going for three walks, bruising has returned. There is absolutely no chance these marks are from any sort of injury. I don’t keep my phone on me while walking, nor can I track my steps precisely, but my usual route covers at least a mile. It seems odd that while I was sedentary all day long, I had no bruises, but now that I've started walking again, I’m experiencing them once more. I’m curious if this is a known issue and whether it’s something I should investigate further. I've reached out on this platform previously, and I don’t have a primary care physician, which makes me reluctant to pay for an appointment just to discuss this bruising. Therefore, I’m seeking insights from here to determine if this might point to a specific condition or if I’m just uniquely prone to this issue. My mother also has a significant bruise on her foot from merely bursting a blood vessel during a foot massage, so maybe it’s a genetic predisposition where our blood vessels are unusually delicate. Who can say? Thank you for your input!
Concerns After Unprotected Encounter with Possible Chlamydia Exposure
I’m a 27-year-old male. Recently, I engaged in unprotected sexual activity with another man. Shortly afterward, he informed me via message that he had received a notification indicating he tested positive for chlamydia. The following day, I visited my doctor and received doxycycline as a preventive measure. From my understanding based on online resources, the correct approach for doxycycline prophylaxis, commonly referred to as "DoxyPep," involves taking two 100mg tablets within 24 hours of exposure. However, the directions on my prescription advised me to take one tablet in the morning and another in the evening for a week. Being cautious, I opted to take both tablets simultaneously. Now I’m wondering if I need to continue with the remaining doses for the next six days. Could I disregard those instructions? I assume those guidelines apply if I already had a confirmed chlamydia infection, correct?
Understanding My Random Hives and Rashes
Hello everyone, I’m reaching out for some insight. I’m a 20-year-old who generally enjoys good health, takes no medications, and has no known allergies. For the past two days, I've been experiencing sudden outbreaks of red, itchy spots on my skin. I visited urgent care yesterday for this issue, but when I arrived, the intense itching and swollen fingers had subsided, and there were no visible signs, so they diagnosed it as nothing serious. However, that night, I noticed red marks developing on my knees and elbows, and this morning, hives appeared on the backs of my legs. I still managed to go to work, and remarkably, the hives vanished by the time I was home. Yet, just a few hours later, they returned, covering my arms and legs once again, and the itchiness has intensified. Aside from this, I feel generally fine, so I don’t think it's urgent. I’m trying to determine the cause behind these irritating rashes; I’ve examined my diet and ruled out any food allergies since I've eaten different meals than usual recently. To eliminate the possibility of bed bugs, I also thoroughly cleaned my bed. I went to the nearest urgent care, but now I'm considering visiting my primary care physician for further evaluation, hoping they might provide more effective assistance. If needed, I can upload photos of the rashes on my profile for a better look. Thank you in advance for your help!
Differentiating Between Histamine Reaction and Cellulitis
Subject: Male Height: 5’4” Status: Non-smoker Current Medications: None On the 15th, I experienced a bee sting. Although it caused some pain and a minor swelling, I initially had no severe reaction. However, after two days, a significant red patch emerged on my skin, accompanied by intense itching. I attempted to relieve the discomfort with calamine lotion and hydrocortisone cream, but neither provided any relief. This morning, I visited a minute clinic where the physician diagnosed me with cellulitis. I was prescribed a ten-day regimen of Cephalexin and a topical anti-itch medication, Triamcinolone, but the itching persists. I am skeptical about the cellulitis diagnosis since the itching is still quite severe. I haven’t experienced any fever or flu-like symptoms, and the redness has begun to fade since this morning. Would it be advisable to also take Benadryl?
Identifying the Cause: Athlete's Foot or Allergic Reaction?
Age: 35, Male Ethnicity: Asian Residence: Bay Area Weight: 125 lbs For the past month, I've been experiencing an issue. Initially, I noticed tiny red spots that were quite itchy. I tried using a topical cream over several weeks, but instead of improving, the lesions expanded and appeared even more unusual. The treatment didn’t seem effective. Could this be a case of hives, as I suffer from them annually, or is it a fungal infection?
