Understanding the Ineffectiveness of Topical Lidocaine
At 33 years old, I have been diagnosed with vulvodynia and persistent vulvar itching of an unknown cause. For the last eight years, I have experienced intense itching in the vulvar area. Initially, I relied on topical lidocaine for relief, using it daily for about two years out of sheer desperation, even though I recognized that prolonged use wasn't advisable. Eventually, I transitioned to using it less frequently, reserving it for the most intense episodes of itching, often at night. However, there came a point when it simply ceased to work altogether. I'm seeking insights into why the lidocaine stopped being effective. It had provided relief for a significant time, so I'm puzzled about this change in its effectiveness. After taking a break for several years, I decided to give it another try, but unfortunately, it failed to alleviate the discomfort this time as well. Any explanations would be greatly appreciated.

It sounds frustrating to deal with persistent vulvar itching, especially after experiencing relief from topical lidocaine. The ineffectiveness of lidocaine over time can occur for several reasons.
Main Points:
- Lidocaine may stop being effective due to adaptation or changes in nerve sensitivity.
- Prolonged use can lead to sensitization of the skin or to chronic irritation.
- Your vulvodynia may have underlying causes that require different management strategies.
Explanation: Lidocaine works by blocking nerve signals in your skin, providing temporary pain relief or numbing. However, if used frequently, your body can adapt to its presence, leading to reduced efficacy. This is sometimes known as tachyphylaxis, where continuous exposure to a medication reduces its effectiveness.
In addition, frequent application can cause skin irritation or a change in the way your nerves react. This irritation can perpetuate or worsen symptoms. Since vulvodynia often has multifactorial causes, including nerve dysfunction, inflammation, or other underlying issues, relying solely on lidocaine may not address the root of the problem.
Next Steps:
-
Avoid Overuse: Limit or stop using lidocaine to prevent potential sensitization and irritation.
-
Moisturize and Soothe: Use gentle, hypoallergenic moisturizers suitable for sensitive skin to keep the vulvar area hydrated, which may help alleviate itching.
-
Identify Triggers: Keep a journal to note any activities, products, or foods that may trigger your symptoms. This could help you identify patterns or avoid irritants.
-
Explore Alternative Treatments: Consider discussing non-medicated options like pelvic floor physical therapy, dietary changes, or other topical treatments with your healthcare provider.
-
Seek Comprehensive Care: If you haven’t already, consider consulting a specialist in vulvodynia or a pelvic floor specialist for a tailored treatment plan focusing on your specific needs.

Managing Early Appendicitis: Antibiotics vs. Surgery
I’m a 21-year-old who recently had a CT scan revealing mild inflammation in my appendix and lymph nodes. My doctor informed me that surgery might not be necessary if the antibiotics effectively alleviate my discomfort by tomorrow.

Concerns Over My Partner's Persistent Pain and Resistance to Seek Medical Help
I’m facing a worrying situation with my partner, a 40-year-old man who stands 6 feet 1 inch tall and weighs approximately 19 stone. Here's a brief overview of his medical background: Twenty years ago, he experienced two instances of deep vein thrombosis (DVT) in his left shoulder. Following the second incident, doctors discovered an abnormal growth of a rib that was pressing against a vein, which was the cause of those DVTs. More recently, he dealt with a blood clot in his calf last year. Fortunately, that was successfully treated, and he returned to his normal health. Although he was advised to continue taking apixaban for the long term, he has, unfortunately, chosen not to follow through with this guidance. He also has a history of elevated blood pressure. For the past couple of days, he has been experiencing two concerning symptoms that emerged simultaneously: a persistent cough with no accompanying cold or flu signs, and a severe pain located on the right side of his torso. He describes this discomfort as being mostly in his stomach yet extending slightly to his back. I would pinpoint the troubled area as the lower part of his ribs along the side of his body. It's unusual for him to express discomfort or complain about his health, so his recent grievances signal to me that the pain is likely quite significant. Despite my repeated suggestions for him to visit a doctor, he insists that he may have simply pulled a muscle. To manage the pain, he's been applying an ibuprofen cream (voltarol) and taking naproxen, but neither seems to provide relief. What might be the underlying issue here? I hope that some medical professionals who see this post can offer their insights, which might persuade him to consider making a doctor’s appointment. I’m open to providing any additional information you might require for a more informed perspective. Thank you for your help!
Struggling with Bleeding and Pain Since Christmas
I'm a 27-year-old woman from the UK, and I've reached a point of exasperation. I'm reaching out because I hope someone can provide insight or guidance on what I should discuss with my doctors. Please excuse any grammar or spelling errors as I have dyslexia. I've been diagnosed with endometriosis and underwent surgery in 2022 for confirmation of that diagnosis. On December 15th, I had my birth control implant removed after nearly two years. During that period, I experienced severe menstrual cramps and PMS. My GP started me on Drospirenone 3mg and Estetrol 14.2mg COCP in October to alleviate these symptoms and suppress my periods, which provided some relief. Prior to this situation, I occasionally dealt with flare-ups that typically lasted a few days or up to a week. To help manage the discomfort, I have been prescribed Duloxetine at a dosage of 90mg. I had an ultrasound earlier this summer, and the results came back normal. Currently, I am awaiting an MRI. Last year, my smear test results were also clear. After the removal of my implant in December, I began bleeding on Christmas Eve. Initially, I could manage with just a panty liner, but over the next few weeks, the bleeding intensified, requiring the use of pads due to increased blood flow and blood clots. Given my history with endometriosis, pain isn't unfamiliar to me; my average pain level is around a 4, but it has recently escalated to 7 or 8. In the past couple of weeks, the discomfort has worsened. My job demands physical activity, and bending over now causes pain in my back and legs. Additionally, I experience discomfort when my bladder fills, and urination is painful, although it doesn't feel like a urinary tract infection. I've also been waking up at night to use the restroom. My doctor performed a urine dip test that showed no signs of infection, though there was blood in my urine, which he indicated was to be expected. Recently, my GP prescribed Tranexamic acid 500mg and Mefenamic acid 500mg, which helped with the blood clots, but I'm still experiencing bleeding and significant pain. I've been diligent about taking my medication, treating it like a strict regimen. I returned to the GP, who referred me for another ultrasound and advised me to go to A&E if the pain worsens. I've been resting as much as possible while still trying to maintain some level of activity, but it hasn't provided much relief. Any assistance or advice would be immensely appreciated! Thank you!
