Understanding Persistent Reactive Syphilis Results Despite Previous Negatives
I’m a 29-year-old female, standing at 5 feet 5 inches and weighing 71 kilograms. As a non-smoker and currently eight months pregnant, I have no history of syphilis symptoms nor any autoimmune disorders. In terms of sexual history, I have had three partners throughout my life, with my current relationship lasting five years. In a regrettable instance prior to meeting my partner, I engaged in unprotected sex just once, which led to a positive chlamydia test that was promptly treated. Before that, I was in a three-year relationship during which I regularly donated blood without any issues regarding test results. About five years ago, my partner and I donated blood together, and my syphilis test returned inconclusive, while his was clear. We were recommended to visit a sexual health clinic, where subsequent tests confirmed that both of us were free from sexually transmitted infections. However, a year later, when I had additional blood tests for health monitoring, the results indicated a reactive syphilis result from my general practitioner. Further testing again confirmed negative results. Fast forward to this year—now pregnant—I received another reactive VDRL result. Upon retesting, the result was again reactive, which I believe was another VDRL test. Notably, the first time I had a reactive result coincided with receiving a COVID vaccine, and this latest occurrence aligns with having received a whooping cough vaccine three weeks before the blood draw. I plan on requesting further testing regarding the recent VDRL to confirm a negative outcome; however, my midwife appears unconcerned about the results. Is there anyone who might shed light on why I repeatedly receive reactive syphilis results? In summary, I have experienced intermittent reactive syphilis results over the last five years, typically concluding with negative outcomes, though the most recent result has been reactive once more.

It's understandable that receiving repeated reactive syphilis test results can be concerning and confusing, especially given your medical history and current pregnancy. Let's break down what could be happening and what you should consider doing next.
Main Points:
- Reactive Syphilis Tests: There are several reasons for reactive results that can be false positives or indicate non-syphilis issues.
- Next Steps: Further confirmatory testing is essential to clarify the situation and determine if treatment is needed.
Explanation:
The VDRL and similar tests are screening tools used for syphilis but can sometimes give reactive results without the presence of the infection itself. Several factors can lead to a reactive VDRL, including:
- False Positives: Conditions like autoimmune diseases, pregnancy, or even previous vaccinations can sometimes cause false positives.
- Vaccine Reactions: You noted that previous reactive results coincided with vaccinations (COVID and whooping cough). While this is not a direct cause of reactive syphilis results, it highlights the potential for non-specific reactions in the body that might affect test results.
- Monitored Health Changes: As pregnancy progresses, hormonal and immunological changes can also affect test outcomes.
Next Steps:
-
Request Confirmatory Testing: It's important to follow up with more specific tests such as the Treponemal antibody test or a rapid immunologic test to clearly confirm or rule out syphilis. Ensure these tests are done promptly for accurate results.
-
Consult Your Midwife/Health Provider: Bring up your concerns regarding the reactive results and express the need for further testing to address your worries about syphilis, particularly given the potential implications during pregnancy.
-
Track Symptoms: Keep a record of any symptoms you may experience. Even though you mentioned not having symptoms, tracking any changes may help in discussions with healthcare providers.
-
Educate Yourself on STIs: Understanding sexually transmitted infections and their tests can help you feel more empowered in managing your health.
-
Consider Counseling or Support: If you're feeling anxious about these results, speaking with a healthcare professional or mental health provider can offer additional support during your pregnancy.
Reassurance:
While repeated reactive syphilis results are understandably alarming, many factors could contribute to these findings, especially in the context of recent vaccinations and your overall health. The key is proactive follow-up with confirmatory testing and having open conversations with your healthcare team to ensure both you and your baby remain healthy.

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?
Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
