Insights on Temporal Bone CT Scan Results Without Contrast
Patient Profile: - Age: 48 years - Height: 5 feet 4 inches - Weight: 209 pounds - Gender: Female - Medications: None - Lifestyle: Non-smoker Presenting Symptoms: - Experiencing pulsatile tinnitus alongside regular tinnitus, ongoing for approximately one month. Clinical Background: After a month of suffering from persistent pulsatile tinnitus, my ENT specialist advised a CT scan of the temporal bone, conducted without the use of contrast dye. I received the scan results over the weekend, but my follow-up appointment with the doctor isn't scheduled for several weeks. While I await the consultation, I'm eager to understand if there are any serious issues indicated by the findings. I recall that a jugular bulb diverticulum can be addressed surgically, though it is generally not life-threatening. This condition began after I experienced influenza and significant stress, and it coincides with occasional instances of regular tinnitus. CT Scan Findings: - Vascular Structures: The sigmoid sinus exhibits a lateral path, accompanied by localized areas of thinning and demineralization observed in the mastoid air cells. Notably, there is a diverticulum oriented laterally at the jugular bulb level, while the carotid canal is encased in bone. - Outer Ear: A mass of irregular soft tissue is noted along the upper boundary of the bony external auditory canal, likely indicative of accumulated debris. The tympanic membrane appears to be intact. - Vascular Structures (Reiterated): The sigmoid sinus continues to follow a lateral trajectory. The sigmoid plate remains undamaged, and a minor diverticulum of the jugular bulb is present. Additionally, bone covers the carotid canal.

The results of your temporal bone CT scan indicate some abnormalities that may be contributing to your pulsatile tinnitus, but they are not necessarily alarming. Here are the main points to consider:
-
Jugular Bulb Diverticulum: This is a localized outpouching around the jugular bulb area and can sometimes be associated with pulsatile tinnitus. It’s generally not life-threatening, and surgical intervention is rarely required unless it leads to significant problems.
-
Thinning and Demineralization of Mastoid Air Cells: This finding can occur due to several reasons, including past infections or congenital conditions. It might not directly relate to your current symptoms but should be monitored.
-
Accumulated Debris in the External Auditory Canal: This could be a minor issue, like earwax buildup or some other material that may need removal, especially if it's affecting your hearing or causing discomfort.
Next Steps to Consider:
-
Monitor Symptoms: Keep a diary of your tinnitus symptoms, noting any changes or triggers you observe. This can help track patterns and provide useful information for your follow-up appointment.
-
Practice Ear Hygiene: Gently clean your outer ear with a damp cloth to avoid further debris accumulation. Avoid inserting objects into the ear canal, which can worsen conditions.
-
Stay Hydrated and Manage Stress: Since stress and illness like influenza often exacerbate tinnitus, find ways to relax and ensure you're drinking enough water.
-
Avoid Noise Exposure: Reduce your exposure to loud noises, which can aggravate tinnitus. If unavoidable, consider wearing ear protection.
-
Educate Yourself: While waiting for your appointment, learn more about tinnitus and possible management strategies. This can help you feel more prepared for discussions with your healthcare provider.
Try to remain calm while you await your follow-up appointment, and know that you are taking proactive steps to understand and manage your condition. If you experience any sudden changes, such as severe dizziness, loss of hearing, or other concerning symptoms, consider seeking prompt medical advice.

Exploring Inositol and CoQ10 for Managing PCOS Symptoms
As a 28-year-old female, I have faced the challenges of polycystic ovary syndrome (PCOS) since my teenage years. Starting from the age of 16, I have dealt with highly irregular menstrual cycles, occurring anywhere from three to eight months apart. My diagnosis has been substantiated through two ultrasounds and blood tests revealing elevated androgen levels. Despite maintaining a healthy diet and leading an active lifestyle—balancing my work as an environmental biologist with gym sessions alongside my husband—I continue to wrestle with weight management. Other symptoms impacting my daily life include significant hair loss, unwanted facial hair, and persistent fatigue. In my journey to manage PCOS, I previously sought counsel from a gynaecologist, who primarily suggested hormonal birth control as the main approach to alleviate my symptoms. Although I adhered to this recommendation for several years, the hormonal changes negatively impacted my mood, leading me to discontinue its use. Another alternative proposed by my gynaecologist involved androgen blockers, but these are not suitable for me since my husband and I plan to start a family in the next two to three years. Recently, my research led me to discover that supplements like Inositol and CoQ10 might effectively combat insulin resistance and lower androgen levels. They are purported to improve various symptoms associated with PCOS, including the regulation of ovulation, all while boasting minimal adverse effects. I am curious about the viability of these supplements as alternatives to hormonal birth control or androgen blockers in managing my PCOS symptoms.
Seeking Clarity on My Spinal Tap Results: A Bit Anxious

Given these results, I'm feeling a bit uneasy and I’m hoping to better understand what they might indicate about my health.
Navigating Ear Infections While Traveling in Thailand
**Age:** 23 **Height:** 6'3" **Weight:** 88 kg **Medication Taken:** 1000mg Bactoclav - Amoxicillin with Potassium Clavulanate, along with pain relief and antihistamines. **Summary:** I’m hesitant to consult a doctor overseas only to receive a prescription for the same antibiotics available at a local pharmacy for a fraction of the price. What strategies can I employ to effectively manage this persistent ear infection? Am I being too hasty in my expectations? I have a long history of ear infections, often triggered by exposure to water or any activity impacting my ears. I regularly use a specialized oil before showering to prevent water from entering my ears. While backpacking in Thailand, I've developed a particularly severe ear infection over the last several days. Initially, a course of 500mg amoxicillin seemed effective, but significantly, just yesterday my condition took a downturn, shifting from nearly healed to painfully inflamed. Now, my ear is not only swollen but also incredibly sore. In an attempt to combat this, I’ve been taking 1000mg Bactoclav - Amoxicillin and Potassium Clavulanate, having consumed seven tablets in the last two days; unfortunately, there's been no noticeable improvement. I’m reluctant to seek medical attention, fearing I would be prescribed the same medication I could acquire from a pharmacy, albeit at a much higher cost. Yet, I’m also starting to question the efficacy of the pharmacy’s medication. I’ve only recently begun the stronger treatment since my symptoms returned. Any advice would be greatly valued! In addition, I’d like to share that just a week into my four-month journey, I feel as though my ongoing ear issues are gradually dominating my life. I am incredibly grateful for this travel opportunity, and while my health isn’t at risk in a serious way, these ear complications are becoming quite overwhelming. Could there be surgical options available? Might there be an underlying health concern that I’m unaware of? It doesn’t seem normal to be plagued by constant ringing, popping sounds, and wax buildup in my ears. Moreover, it feels excessive to have to apply products in my ears every time I shower.
Injury to the Sciatic Nerve
At 25 years old and weighing 135 pounds, I am currently taking naproxen and Lyrica to manage my sciatic nerve injury. The pain in my right leg has made it incredibly difficult for me to remain upright. It’s been two weeks since I first sought treatment; I consulted a physician who advised medication and attended a physiotherapy session. Initially, I experienced some relief after the appointment, but unfortunately, the pain returned the following day—even the prescribed home exercises exacerbated my discomfort. Just yesterday, I attempted the cobra pose, along with the flossing technique, which only heightened my pain. I find it nearly impossible to stand for more than a few seconds before the discomfort becomes intolerable. Additionally, I have an appointment with an osteopath on Tuesday, but I can't shake off my worries— is it normal to still struggle with walking after two weeks? Although I am experiencing some numbness in my toes, I haven’t encountered any loss of bladder or bowel control, worsening numbness, or weakness in my legs, so I feel stable in that regard. Nonetheless, I fear the possibility of never fully recovering and being left with a lasting disability. The pain is overwhelming, adding to my anxiety about the future.
Inquiry Regarding Metronidazole Use for Recurrent Bacterial Vaginosis
I am a 32-year-old female, measuring 5 feet 5 inches tall and weighing 248 pounds. My current medications include Vyvanse at a dosage of 40mg, a medication for asthma, vitamin D, a 325mg iron supplement, and as of now, I am also taking amoxicillin to treat strep throat. I am about to begin using Metronidazole 0.75% Vaginal Gel, with a total of 70 grams available. The instructions indicate that I should administer 5 grams vaginally twice a day for seven days, followed by twice a week for a period of two months. During the initial treatment phase when I will apply the gel twice daily, I anticipate abstaining from sexual activity. However, once I transition to the twice-weekly application, is it permissible to engage in sexual intercourse? I would normally consult my physician about this matter, but she is currently unavailable, and the nurse is also out of the office, which is quite frustrating.
