Impact of Kenalog Injections on Menstrual Cycles
I am a 34-year-old female, weighing 300 pounds and standing at 5 feet 9 inches tall. I have Hashimoto's disease as well as premature ovarian dysfunction, which generally prevents me from ovulating. As a result, my menstrual cycle typically involves withdrawal bleeding about every 34 days, with dates that can vary considerably. I am not using any form of birth control. What influence might Kenalog injections have on menstrual cycles? My last period began on August 24th, and I received a Kenalog shot in my sacroiliac joints for back pain on August 27th. My period ceased on August 29th, and I experienced a single day without bleeding on August 30th. However, on August 31st, I began spotting. Now, I find myself in the midst of a substantially heavier period, and it has persisted for eight days as of now, which is quite perplexing to me.

Kenalog (triamcinolone) injections can have various impacts on menstrual cycles, particularly in women with underlying hormonal conditions like Hashimoto's disease and premature ovarian dysfunction. It's important to recognize that while not all women will experience changes in their menstrual cycles due to Kenalog, hormonal treatments or injections can sometimes lead to alterations in bleeding patterns.
Explanation:
The corticosteroid in Kenalog works by reducing inflammation, but it can also influence hormone levels, including those related to menstrual cycles. In women with existing hormonal imbalances or menstrual irregularities, such as premature ovarian dysfunction, the introduction of Kenalog could potentially exacerbate these imbalances or lead to changes in menstrual bleeding patterns.
In your case, the changes you've experienced—transitioning from withdrawal bleeding to a heavier period shortly after receiving the injection—are noteworthy, especially since your cycles are already irregular. The heavier bleeding you're experiencing could be a response to the injection, especially if your body is reacting to the medication or if there are changes in your hormonal regulation.
Next Steps:
-
Track Your Symptoms: Keep a detailed log of your menstrual cycle and any other symptoms you may be experiencing. Note the timing, flow, and any additional symptoms like pain or fatigue.
-
Hydration and Self-Care: Ensure you are staying well-hydrated and managing discomfort. Over-the-counter pain relievers, such as ibuprofen, may help with any cramping or discomfort associated with heavier periods, but follow the recommended dosages.
-
Monitor for Severe Symptoms: If you experience significant side effects—such as soaking through a pad or tampon every hour for several hours, severe pain, or any other concerning symptoms—consider seeking further evaluation.
-
Consult Your Healthcare Provider: Given your history of hormonal issues and the current changes in your menstrual cycle, it’s important to discuss these developments with your healthcare provider. They can assess the impact of the Kenalog injection on your hormone levels and explore whether further intervention may be necessary.
By monitoring these changes and remaining in communication with your provider, you can better understand how Kenalog is affecting your menstrual cycle and address any concerns effectively. Let me know if you need more details or support!

Concern Regarding Blood in Semen at Age 26
I am experiencing an issue where there appears to be blood in my semen. I am a 26-year-old male, 168 cm tall and weigh 74 kilograms. Let me explain the situation in detail. Last Thursday and Friday, I was engaging in edging. During the sessions, I approached the point of climax but managed to refrain from finishing. By Friday evening, I started suffering from intense pain in my lower back, coupled with a headache. I took some aspirin, which alleviated both my back pain and headache. On Saturday, I attempted edging again, but by the afternoon, I found it impossible to continue without releasing. To my shock, the semen I produced was tinged with a light pink color, which sent me into a panic—I started sweating profusely and felt faint. Later that night, I decided to masturbate again to see if the blood was still present. Initially, the semen appeared clear, but then it turned slightly pink, and the last bit looked as if blood was dripping. Today, I tried masturbating once more; it started clear but, toward the end, I noticed actual drops of blood. Additionally, I've been having trouble falling asleep for the past six months. Recently, I’ve also noticed painful lumps in my armpits. I am extremely worried about this situation and feel uncertain about what steps to take next. P.S. I created this account solely to seek help regarding this matter.
Worried About My Four-Year-Old Daughter
Greetings, I am reaching out regarding my daughter who just celebrated her fourth birthday. Currently, she stands at 3 feet 9 inches tall and weighs approximately 48.5 pounds. Recently, I've noticed several small bumps forming around her right eye. Initially, this issue presented itself a few months ago with a single white spot, but it has since progressed. We consulted with a physician, but they were unable to provide a definitive diagnosis; they suggested it might be molluscum contagiosum, although they weren’t certain. The doctor advised us to monitor the situation and return in a few weeks if the bumps persist. Just a few days ago, one of the bumps ruptured, and there was a bit of blood. Fortunately, my daughter doesn’t appear to be in discomfort—it doesn’t seem to cause her pain or itchiness. However, she used to mention that her eye was watery before the bumps emerged. If anyone has any insights into what this condition might be, I would deeply appreciate your input. Thank you for your help!
Understanding Low White Blood Cell Counts
Age 37, Caucasian male. For just over two years now, I have been undergoing testosterone replacement therapy (TRT), which necessitates regular blood tests approximately every three months. A continual finding from these tests is that my white blood cell (WBC) count consistently falls beneath the standard reference range, typically measuring around 3.3 to 3.4. A similar pattern is observed with my platelet levels. Medical professionals have indicated that as long as I am feeling well, this might simply reflect my normal baseline. In my latest blood test results, my WBC count dropped to 3.0, with platelets also reported below the reference range. Upon reviewing previous laboratory results from annual evaluations, I realized that prior to 2019, my counts had been significantly higher, usually in the mid-6 range. Notably, from the year 2018 to 2020, my WBC count has nearly halved and has remained stable at this lower level for approximately five years. This situation raises questions for me regarding whether it warrants further investigation, specifically whether I should consult a hematologist. I can definitely observe that I experience illnesses more frequently than I did in my twenties; however, apart from the low WBC and platelet counts, I generally feel healthy in my everyday life, without any alarming symptoms to report.
Strange Line Near My Eye?
I’m a 25-year-old and recently observed a peculiar line near the outer corner of my eye this past Friday evening. It hasn’t disappeared since then, and I hadn’t seen it before that moment. Thankfully, it’s not causing me any pain or disrupting my vision. Does anyone have any insight into what could be going on? I would greatly appreciate any advice or suggestions. Thank you!
Considering the Transition from Pill-in-Pocket Flecainide to Daily Use for Atrial Fibrillation
Greetings! I’m a 65-year-old male currently prescribed 95 mg of metoprolol CR, 20 mg of quinapril, and 100 mg of aspirin on a daily basis. I also use 300 mg of flecainide as needed for my atrial fibrillation episodes. For the past 12 years, I have experienced atrial fibrillation paired with rapid ventricular response. Whenever these episodes occur, I take the 300 mg flecainide pill, which typically resolves the arrhythmia within a timeframe of one to six hours. In addition, I have a condition known as Muir-Torre Syndrome due to a mutation in the MLH1 gene, and I maintain a regimen of 100 mg of aspirin. This is based on preliminary research suggesting that a daily dose of aspirin may lower the risk of colon cancer, a condition I have faced twice. My cardiologist is cautious about incorporating rivaroxaban into my treatment plan alongside aspirin. Instead, he focuses on maintaining rhythm control aggressively. My inquiry is regarding the appropriate time to transition from using flecainide on an as-needed basis to a daily regimen with the hope of preventing future atrial fibrillation episodes. Recently, I have experienced two episodes within a two-week period; however, I have a history of similar occurrences that were followed by 2-3 months without any incidents. I manage the flecainide well and, according to my last echocardiogram in July 2025, I have a structurally normal heart.
