Kneecap Dislocation: Understand the Cause and Next Steps
As the title indicates, I'm a 22-year-old female who recently experienced a troubling incident wherein my kneecap dislocated spontaneously, leading to severe discomfort. In the midst of this pain, as I collapsed, it re-aligned itself. A similar occurrence took place years ago with my other knee. Throughout the years, I have also dealt with numerous ankle sprains. I underwent an X-ray today, which returned normal results, and I was subsequently sent home with no further action taken. Additionally, I am concerned whether it was safe to undergo the X-ray, as I am currently in my third trimester of pregnancy. The radiographer did not allow me to wear a lead apron, claiming it would "trap" the radiation. Given these circumstances, should I consider further examinations for my joints? The dislocation happened while I was merely walking on a flat surface, and just a few days prior, I had a near-sprain in the same leg when it rolled, although fortunately, it didn’t result in a significant injury. I appreciate any guidance you can provide.

It sounds like you're dealing with quite a challenging situation regarding your knee dislocation and your overall joint stability, especially while being pregnant. Let’s address your main concerns and guide you on the next steps to take for your knee and any possible further examinations.
Main Points:
- Kneecap Dislocation: This can be caused by a variety of factors, including joint instability or a prior injury, which seems relevant in your case given the history of similar incidents and ankle sprains.
- Safety of X-ray During Pregnancy: Generally, the risk from an X-ray during the third trimester is minimal, especially if the area scanned is the knee, which is far from the abdomen. The radiographer's rationale about the lead apron is also aligned with standard practice; it’s typically used for abdominal imaging or when the radiation field could affect reproductive organs.
Explanation:
A dislocated kneecap often occurs due to instability in the joint, which might be made worse by previous injuries or sprains. When there's an incident of dislocation, even if it reduces on its own, it’s important to consider the underlying cause. Given your experience of a prior dislocation, it may indicate a tendency for this to occur, which could warrant further evaluation.
Pregnant women can safely undergo X-rays if necessary. The risk of radiation exposure while using standard precautions is very low, and your healthcare team assesses the necessity of any imaging carefully.
Next Steps:
- Monitor Symptoms: Keep track of any pain, instability, or swelling in your knee. If these symptoms persist or worsen, it’s critical to reassess them.
- Activity Modification: Avoid high-impact activities that might put stress on your knee, like running or jumping. Stick to low-impact exercises such as swimming or cycling if your healthcare team approves them.
- Strengthening Exercises: Consider gentle strengthening exercises for your knee and surrounding muscles. Focus on quadriceps and hamstring strengthening to stabilize the knee joint. You may want to consult with a physiotherapist for tailored exercises, especially for your pregnancy.
- Joint Stability Assessment: Given your history, seeking a referral to a specialist, such as an orthopedic doctor, may be beneficial. They can evaluate your knee stability more comprehensively, possibly with further imaging or physical exams as needed.
- Follow-Up Care: After your baby’s birth, you might want to reassess your joint health more thoroughly, as the hormonal changes during pregnancy can temporarily affect joint stability.
I hope you find this information helpful and encouraging. Please take care of your body and reach out if you have further questions or concerns about your joint health or any other matters.

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.
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.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
