Could This Be Lyme Disease on My Arm?
I need some guidance. Approximately 18 hours ago, I discovered a small bite on my arm, which has since expanded significantly. It's now around 4 to 5 inches in diameter, feels warm to the touch, and has become raised and firm. While there is no itching, the warmth is evident. Interestingly, I’m not experiencing any pain or other noticeable symptoms. I’m a 33-year-old white female in generally good health, though I do have a history of hay fever. This is occurring in the UK, and I have spent a fair amount of time lying on grass over the past few days.

It sounds like you’re experiencing an unusual reaction to a possible insect bite, and your concern about Lyme disease is understandable given your outdoor activities. Here are the main points to consider:
-
Possible Insect Bite Reaction: The raised, warm area around a bite can indicate a localized reaction. This is fairly common and can occur with various insect bites.
-
Lyme Disease Risk: In the UK, Lyme disease is primarily associated with bites from infected ticks. If you were bitten by a tick, it can be a concern, but not all bites lead to Lyme disease.
Explanation:
The symptoms you're describing—an expanding rash that is warm and firm—may indicate a local inflammatory response to an insect bite, grass, or other allergens, especially since you have a history of hay fever. The absence of pain is a good sign, but monitoring your symptoms is important.
Next Steps:
-
Monitor the Bite: Keep an eye on the area for changes. Check for any signs of increased redness, pain, or new symptoms like fever or headaches.
-
Self-Care for the Area:
- Keep the bite area clean and avoid scratching it.
- You may apply a cool compress to reduce swelling and warmth.
- Over-the-counter antihistamines can help manage any allergic reactions if they develop.
-
Watch for Warning Signs: Be alert for the following, which could indicate Lyme disease or another infection:
- A circular target-like rash (often associated with Lyme disease).
- Fever, chills, body aches, or fatigue.
- Flu-like symptoms or any unusual symptoms in the days after the bite.
-
Seek Help if Necessary: If you notice any of the above symptoms or if the bite worsens after a few days, it would be wise to consult a healthcare professional for further evaluation.
Please remember to take care of yourself and don’t hesitate to reach out for help if you feel concerned as symptoms progress. If you need further advice or assistance, feel free to ask.

Unexpected Nasal Issues After Head Injuries
I am a 46-year-old male, standing at 1.84 meters (6 feet) and weighing 84 kg (185 lb). Last year, I had an unfortunate incident while changing my car's license plate in a parking lot. As I stood up, I accidentally bumped my head against the edge of a storage unit. Initially, I felt fine, but two days later, while reaching down to pick up a toy my child had left on the ground, I noticed a small, watery liquid leaking from my nose. This unexpected occurrence caused me some concern, as I had never experienced anything like it before. Being that my health insurance was lacking at the time, I decided to visit Mexico for a medical consultation, suspecting it could be a cerebrospinal fluid (CSF) leak. During my trip, I found that bending down didn’t produce any discharge, but if I lay on my right side, a significant amount of yellowish fluid would drain from my nose. The first instance was alarming enough to create a sensation of drowning, although it only lasted a few moments. This event repeated twice more the following day, and I even demonstrated it to my mother, who is in the medical field. An MRI and examination by an ear, nose, and throat specialist yielded no abnormalities. They speculated that it might be a coincidence or possibly sinusitis. Meanwhile, the leakage persisted, though it seemed to shift from my nose to the back of my throat. I had assumed I needed to adapt to this situation. Doctors suggested that allergies in my living environment could be causing such excessive drainage, which ultimately prevented the formation of typical mucus and prompted a watery discharge instead. Fortunately, after several months, the issue resolved itself without any clear timeline of its duration since my concern had diminished. Fast forward to 2024: while playing with my kids at a playground, I was bending over to catch one of them when I collided with a tube on the structure, hitting my head yet again. This incident worried me since I feared a recurrence of my previous problems. Sure enough, a few days later, I began to notice a wet sensation on the left side of my nose, with the liquid once again draining towards the back of my throat. I sought help at the emergency room; an MRI confirmed that nothing was amiss, yet I endured persistent headaches for nearly two months. To cope, I began wearing a hat to distract from the mild discomfort, which felt more like surface irritation than anything within my head. Concurrent with these symptoms, I noticed that I was struggling to recall certain words, which unnerved me, especially since English isn't my first language. I remember distinctly forgetting the word "butter" and experiencing difficulty recalling common names and terms. The fear of possibly developing dementia prompted me to consult a neurologist, which culminated in a panic attack—a new and unsettling experience for me. However, he reassured me that my condition was manageable. People around me attributed my symptoms to stress, exacerbated by job-related anxiety and visa uncertainties at that time. A subsequent MRI showed normal results. I traveled to Mexico in December, but the trip began poorly as my ability to focus remained severely compromised. However, after some weeks, I felt improvement; I started recalling words more easily, and my overall clarity returned, making life more manageable, both personally and at work as a software developer. Just last week, I faced another setback when, while tying my shoes, my child accidentally kicked me in the head. The familiar watery sensation returned, alongside a recurrence of throat irritation. I waited in hopes that the symptoms would subside, but by last night, the headache reappeared, this time localized on the right side of my head. Concerned, I returned to the emergency room for evaluation. Once again, they conducted imaging and determined there were no apparent issues. This morning, I noticed soreness in my throat while drinking, consistent with the previous episodes. I'm currently feeling a moist sensation on the left side of my nose as I type this out, and I’m perplexed because I have sought advice from two ENT specialists and two neurologists, all concluding that my MRI results were normal. One neurologist mentioned the possibility of collecting the fluid for further examination to check for a CSF leak, though obtaining a sufficient sample is challenging since the sensation doesn’t consistently produce a noticeable amount of liquid. It's frustrating not knowing whether these symptoms are stress-related, coincidental allergies, or something more significant. During my last emergency visit, a doctor suggested that perhaps my sinuses react unusually following head injuries. I find myself at a loss for what to do now and thought I might seek advice on Reddit, hoping to connect with others who might offer insight. If anyone has recommendations for a doctor in the Los Angeles area who could assist me, I would sincerely appreciate the help. I haven't yet received the scans from last night but intend to follow up with the hospital this week.

Discomfort in Big Toenail After Extended Standing
Today, I spent about five hours assisting with grape harvesting. Although I’ve walked for long durations in the past, I haven’t stood still for such a lengthy period before. The terrain was somewhat uneven, which added to the challenge as I remained in one spot for quite some time. Upon returning home and finally relaxing, I realized that my big toenails were experiencing discomfort. It felt like there was a pressure emanating from beneath the nails. While my little toes felt slightly similar, the sensation was much more pronounced in the area of the big toenails. After noticing the discomfort, I examined my toenails. They appeared neither red nor bruised. A few hours later, I took a photo in a dimly lit room, and it seemed to reveal a slight pinkish hue at the top of the nail beneath the white section; however, this area wasn’t the source of pain. The pressure and soreness are concentrated more towards the center of the toenails. I can confidently say this is not an issue with ingrown toenails, as I have encountered that problem previously, and this experience feels entirely different.
Concern Over Nail Integrity
I've been dealing with paronychia and have spent the past week on antibiotics for treatment. However, as my nail begins to grow back, I've come across an unsettling issue: the left side, where the infection had been trapped beneath my nail, now features a hole in the nail bed. It appears almost detached from the base of my finger, which is causing me quite a bit of concern. I'm feeling quite anxious about how this will affect the nail's growth moving forward, and whether it could lead to my nail completely coming off. I would appreciate any advice or information regarding this matter. I'm a 21-year-old female, 5 feet 8 inches tall, weighing 160 pounds, generally in good health, a non-smoker, and without any significant health problems aside from this issue.
Seeking Answers for Persistent Chest Pain – Is It Really Anxiety?
For the past three years, I have been grappling with an intense pain that begins in the center of my chest, often described as a crushing sensation. During those initial months, I underwent numerous tests, including ECGs, X-rays, CT scans, and blood work, all of which resulted in normal findings, leading medical professionals to attribute the discomfort to anxiety. Recently, however, the nature of my pain has evolved. It now appears slightly off-center, encompassing areas above and below my pectoral muscle and extending down my left side, from the armpit all the way across my ribs. This past three-month period has been particularly challenging. I've visited the emergency room three times due to the persistent pain, once again undergoing blood tests and ECGs only to be reassured that everything is normal. The sensation I experience nowadays is more of a dull ache that can strike at any moment without any prewarning. It often clings to me for days on end, spanning 1-2 weeks before receding, only to make a return. The intensity of this pain can vary significantly, from mildly bothersome (2 out of 10) to extremely severe (8 out of 10). When I apply pressure to specific areas of my chest, it feels as though there is an internal bruise being squeezed around my ribs. While my doctors consistently insist it's anxiety, I consulted another physician to explore the possibility of costochondritis, which they acknowledged as a potential diagnosis. I asked for a referral to a musculoskeletal specialist, but was told that there isn’t much that can be done, as costochondritis typically resolves on its own, albeit with the possibility of recurrence. They suggested I take ibuprofen, but I mentioned that it has not alleviated my symptoms, and that conversation ended there. Am I destined to endure this discomfort indefinitely? Does this situation indeed suggest costochondritis? The weight of this issue is becoming overwhelming, and at just 28 years old, I am desperate for relief.
Red Marks on Skin
I'm a 29-year-old female, 5'8" tall, and I'm not taking any new medications. Recently, I noticed some red marks on my arm when I woke up. Initially, I thought it might be a burn from the heating pad I used, but after about a day, they disappeared. However, this morning I discovered a similar red patch on my left breast. It's not raised, doesn't cause any pain, isn't itchy, and feels cool to the touch. The skin texture is normal compared to the unaffected areas around it. Does anyone have an idea about what this might be?
