Persistent Itching and Burning Around Neck and Scalp - Should I Keep Using Cephalexin?
Greetings, I’m a 35-year-old female. I recently developed a rash that began on the back of my neck and subsequently spread to my ears. After consulting with my physician, I was prescribed ketoconazole shampoo to address a suspected fungal rash. Despite using it diligently for four days, the condition actually aggravated, affecting my ears, the back of my neck, and my scalp more significantly. Seeking further assistance, I visited an urgent care facility where the medical staff suggested that I might be experiencing bacterial folliculitis. As a result, they prescribed cephalexin, which I am to take at a dosage of 500mg three times daily for a week. I took my first dose yesterday, yet the intense itching and burning sensations persist without improvement. Is it advisable for me to continue the medication? How long does it typically take to see improvement? Is it common to experience these symptoms alongside bacterial folliculitis? I appreciate your time and any guidance you can provide on this matter!

It sounds like you're experiencing a challenging situation with persistent itching and burning around your neck and scalp. Bacterial folliculitis can indeed cause these uncomfortable symptoms, and while cephalexin is typically effective in treating such infections, it may take some time to see improvement.
Key Points:
- Current Condition: Persistent itching and burning may be part of ongoing inflammation or irritation, even if you're on antibiotics.
- Medication Guidance: It's essential to continue taking cephalexin as prescribed unless advised otherwise by a healthcare professional. Antibiotics often take several days to show noticeable improvement.
- Symptoms and Folliculitis: It is common to experience itching and burning with bacterial folliculitis, as the hair follicles become inflamed.
Explanation:
- Bacterial folliculitis often manifests as red, itchy bumps and can feel uncomfortable. The recommended antibiotic, cephalexin, helps combat the bacterial infection, but improvements may not be immediate. Generally, it can take anywhere from a few days to a week to start seeing relief, as the medication works to reduce the infection and associated inflammation.
Next Steps:
- Continue Medication: Take cephalexin as prescribed (500 mg three times daily) for the full duration, as stopping early can lead to incomplete treatment.
- Monitoring Symptoms: Keep an eye on your symptoms. If itching and burning persist beyond a week on cephalexin with no improvement, or if you develop new symptoms like fever or worsening rash, consider seeking further medical advice.
- Symptom Relief: To manage the discomfort, you may apply cool compresses to the affected areas or consider over-the-counter antihistamines to relieve itching, but ensure these are safe to use in combination with other medications.
- Avoid Irritants: While undergoing treatment, keep the area clean and avoid any potential irritants like harsh soaps or hair products.
I understand this can be frustrating, but with continued monitoring and adherence to your medication, improvement should come. Please feel free to reach out if you have more questions or need further reassurance!

17-Year-Old Female Experiencing Chronic Acne Scarring on Back and Arms Despite Prescription Remedies
Age: 17 Gender: Female Country of residence: United Kingdom Skin type: Dark / Black Medical background: No significant health issues Medications: Previously utilized azelaic acid and benzoyl peroxide Timeframe: Many months to years following acne resolution Greetings, I am a 17-year-old girl dealing with long-lasting scars on my back and upper arms from acne, which have not improved even after following prescribed treatments. In the past, I experienced acne primarily on my upper back, shoulders, and arms. While the active breakouts have largely ceased, I am left with noticeable dark spots and irregular skin texture. The scars I have include: • Dark brown hyperpigmentation • Certain areas appear slightly sunken • Uneven or coarse surface • No raised or keloid scars present My GP prescribed azelaic acid and benzoyl peroxide, which I applied regularly. Unfortunately, the azelaic acid did not significantly lighten the scars and seemed inadequate for the pigmentation level. Although benzoyl peroxide was effective against my active acne, it did not enhance the appearance of the scarring. The marks have been present for a considerable time and are quite stark against my skin tone. I do my best to avoid picking at my skin and maintain proper hygiene, yet the scars aren’t diminishing on their own, which is negatively impacting my self-esteem—especially when I wear sleeveless or backless outfits. Currently, I'm exploring the possibility of using retinoids like adapalene or tretinoin. However, I’m uncertain if these would be suitable or effective for treating scarring on my back and arms, particularly with my darker skin type. I would like guidance on the following questions: • Does this seem to be primarily post-inflammatory hyperpigmentation, atrophic acne scars, or possibly a combination of both? • Is azelaic acid effective for this type of scarring, or are more potent treatments generally required? • Are topical retinoids such as adapalene or tretinoin advisable for this sort of scarring? • What treatments are typically recommended for acne scars on the back and arms in individuals with darker skin tones? • Should I insist on a referral to a dermatologist, or is it better to attempt specific topical therapies first? Any insights or recommendations you could offer would be greatly appreciated.
Concerns About Hearing Loss After Extended Earphone Use
For the past two and a half years, I have primarily relied on in-ear earphones, with the right one typically experiencing less usage—mostly for short videos or brief instances. Recently, during a singing session, I noticed something unusual. I covered one ear to monitor my pitch, and I was surprised to find that my hearing felt unclear and somewhat muffled. This was an experience I hadn’t recognized before. After conducting a few tests by alternately covering each ear, I discovered that my left ear can hear clearly and accurately, while my right ear perceives sounds as muffled, as if there’s a barrier in front of the speaker. I’m seeking advice as a 17-year-old student from Pune, India, with financial constraints that prevent me from adding stress to my parents. I’m deeply concerned whether this issue could be permanent, and if there’s any possibility of recovery. Although I can still hear sounds from my right ear when they are very close, I am unsure of the next steps. I have made the decision to discontinue using earphones starting today, but I’m wondering what additional measures I should take. Would it be advisable to pursue an audiometry test or consult an audiologist for a professional evaluation?
Dealing with Possible Epididymitis
A male, aged 40, standing at 5'9" and weighing 10.5 stone, presents a health concern. He has a history of smoking but refrains from alcohol consumption. For several years, I've grappled with a weakened bladder. However, over the last year or two, I've been experiencing intense discomfort in my right testicle. Initially, I thought I discerned a lump, prompting me to reach out to a physician. Unfortunately, the advice I received was limited; the doctor recommended an STI screening without conducting any examinations. I complied with the test, which returned negative results. Although the pain subsided briefly, it has now returned with greater intensity. I have undergone blood tests focusing on kidney, bladder, and prostate functions, all of which yielded normal results. Now, the medical team is leaning towards a diagnosis of epididymitis. The pain is excruciating and difficult to endure. I’ve scheduled an appointment for a prostate and testicular examination, which may lead to an ultrasound scan or possibly a urethral procedure to eliminate any serious underlying issues. The thought of the forthcoming examination fills me with anxiety, as I'm certain it will be painful. I'm curious if anyone has experienced epididymitis and what outcomes you faced, including any surgical interventions that may have been necessary.
Concerns Regarding Neck Pain After Lifting Incident
I’m a 27-year-old man, standing at 174 cm and weighing 63 kg, residing in Australia. Earlier today, I attempted to lift a heavy case using only one hand. Unfortunately, I didn't realize it was unlatched, and when it opened unexpectedly, I felt significant stress in my lower neck and upper shoulder area. Approximately four hours later, I began to experience a pulsating discomfort on the left side of my neck, extending from beneath my ear down towards my collarbone. I have a medical background of neurological issues related to my vision, along with episodes of facial drooping that are currently under investigation. After the initial neck discomfort (which subsided quickly), I noticed a resurgence of blurriness in my vision. Could this incident have caused an injury to my neck that might be aggravating my neurological symptoms? Is there a chance that this situation could be a vascular emergency?
