Query on Hematology: Prothrombin G20210A vs. Low Protein S Function
I recently visited a hematology specialist to undergo testing for the Prothrombin G20210A mutation since my mother has a heterozygous gene variant. Instead of focusing on this specific genetic test, the doctor opted for an aPPT panel, which revealed my Protein S levels were at 20, whereas the typical range is between 60 and 150. She's advised against using birth control and suggested a daily regimen of baby Aspirin. However, I found it challenging to grasp the distinctions between the two issues—the low Protein S levels and the Prothrombin mutation. Could my low Protein S levels be the result of the Prothrombin condition? Is it feasible for me to have both factors at play? Additionally, might the birth control contribute to the decline in Protein S levels, allowing me to continue using it alongside the Aspirin? I also have a history of high blood pressure tied to obesity, which is now managed with Wegovy. Any insights or clearer explanations on this matter would be greatly appreciated.

It sounds like you have some important questions about the tests you've undergone and how they relate to your overall health, especially concerning your low Protein S levels and the Prothrombin G20210A mutation. Let's clarify these points.
Main Points:
- Low Protein S Levels: Your Protein S level is lower than the normal range, which affects your blood's ability to prevent clotting.
- Prothrombin G20210A Mutation: This genetic variant can increase the risk of blood clots but does not directly cause low Protein S levels.
- Interrelationship and Birth Control: Hormonal birth control can indeed lower Protein S levels, creating additional clotting risks.
Explanation:
Protein S plays a crucial role in regulating blood clotting. Low levels can lead to an increased risk of clots. Your Prothrombin G20210A mutation can also heighten this risk independently. While both factors can influence clotting tendencies, low Protein S is not a direct result of the Prothrombin mutation.
Regarding birth control, it can impact various proteins involved in blood clotting, including Protein S. That's likely why your doctor advised against it, especially given your low levels.
Next Steps:
- Avoid Birth Control: Follow your doctor's advice and abstain from hormonal birth control, as it may increase your risk of clots.
- Daily Aspirin: Continue with the daily baby Aspirin as recommended, since it may help reduce the risk of clotting.
- Monitor Symptoms: Keep track of any symptoms such as leg swelling, redness, or pain, which could indicate clotting issues.
- Lifestyle Modifications: Maintain a healthy weight, follow your high blood pressure management plan with Wegovy, and engage in regular physical activity to support overall cardiovascular health.
- Regular Follow-Up: Stay in touch with your healthcare provider for ongoing monitoring and to discuss any changes in your health.
If you have lingering questions or concerns, consider reaching out to your healthcare provider for further clarification. They can provide personalized insights based on your unique health situation.

Severe Pain on the Right Side of My Face for Two Days
Hello, I’m a 26-year-old female, and I’ve been enduring significant jaw pain for about five years due to excessive clenching. I consulted a healthcare professional once, and they indicated that there might be an issue with my joints. Usually, I deal with daily discomfort and pressure in my jaw; however, for the past two days, the right side of my face has experienced intense pain. It feels as though the area near my nose is under extreme pressure, almost like it could burst. My teeth are incredibly sensitive, and I can sense a discomforting line extending along the right side of my face. I also experienced a bit of dizziness today. I am in the process of scheduling an appointment, but the earliest slot is a week away. My friends advise that this isn't an emergency situation, but the pain is unbearable, and I’ve never gone through anything like this previously. Additionally, there are no visible signs of swelling; all symptoms seem to be internal. Can anyone offer guidance?
Experiencing Pain in My Throat While Eating
Hello! I'm a 19-year-old female, standing at 5 feet 6 inches and weighing 170 pounds. My current medications include Adderall (20mg daily), Lexapro (20mg daily), and Singulair (10mg daily). I do not consume alcohol, smoke, or use recreational drugs. I've been identified as allergic to clindamycin and amoxicillin, with a suspected allergy to pumpkin as well, but I haven't encountered any of these substances recently. I reside in the United States. Starting on Sunday, February 1st, I noticed that I felt discomfort in my throat when I ate pasta. This sensation was unlike a typical sore throat; it felt somewhat swollen and had a bruised quality to it. After pausing to let it pass, the discomfort subsided. However, upon taking another few bites, the issue reappeared, and I ultimately decided to stop eating. Later that evening, when I tried a piece of bread, the same discomfort returned but faded within two minutes after stopping. On Monday, February 2nd, I managed to have a protein shake in the morning without any issues. Later, I attempted to eat popcorn, and again the discomfort reoccurred. Today, February 3rd, I had cherry tomatoes, which didn’t cause any problems. However, just an hour ago, I had some bread again and experienced the same throat pain, which lingered for about ten minutes, although this time it was somewhat less uncomfortable. I also had a few small pieces of brownie afterward, which I was fine with. All these foods are familiar to me and have not been new additions to my diet. The only recent change in my routine was the reintroduction of Zepbound. I had started Zepbound in February 2024 and had to stop in October 2025 due to access issues. Prior to this, I never experienced any throat problems. I took my first dose of Zepbound (5mg, which was my previous dosage) on Saturday, January 31st. This change is the only differing factor, as I've never dealt with such sensations before.
Understanding Bladder Discomfort
At 25 years old, residing in Germany, I find myself facing some concerning bladder issues after a previously uneventful medical history regarding my urinary system and gynecological health. Approximately six months ago, I encountered my first urinary tract infection (UTI). Since then, I have experienced a series of suspected infections, treated on multiple occasions with various antibiotics, including fosfomycin (twice), trimethoprim, and cefpodoxime, the latter being administered in October. During a follow-up appointment in early January, I was informed that there were no active infections present; however, my symptoms have continued without relief. My symptoms appear in sporadic episodes, characterized by a burning sensation and significant pressure in my lower abdomen and bladder. Roughly every few weeks, I face episodes of intense urgency to urinate, although these symptoms do not persist continuously. Laboratory tests consistently reveal a high leukocyte count in my urine, estimated around 125, with nitrite and blood tests returning negative results. A recent urine culture failed to detect any typical uropathogens, indicating potential sample contamination. During a gynecological examination, my doctor noted inflammation in the vaginal mucosa, an elevated vaginal pH, and recurring yeast infections. Upon suspicion of a local estrogen deficiency potentially linked to PCOS, I was prescribed a topical antifungal treatment and a local estrogen cream. The estrogen cream offered some relief in the initial days; however, around the third or fourth day, the classic UTI-related symptoms resurfaced. Despite the yeast infection diagnosis, I have not experienced the usual itching associated with such infections. I also encountered discomfort from a lactic acid gel that resulted in severe burning sensations—this was intolerable. In addition, I tried treatments like fluconazole once, cranberries, D-mannose, and forskolin in hopes of alleviating my symptoms. Imaging studies conducted thus far include: - A CT scan: which returned normal findings, - An ultrasound examining both kidneys and bladder: also normal. My healthcare provider has recommended a cystoscopy for further evaluation, yet I am grappling with significant anxiety regarding the procedure, particularly since it would be performed without sedation. I am left wondering what might be causing these ongoing issues with my bladder.
Long-Term Effects of Using Heavy Bows on Joint Health
Age: 31 Gender: Male Height: 5'9" Weight: 190 lbs Ethnicity: Caucasian Duration of Symptoms: 1 week Affected Areas: Left clavicle near the sternum and behind the left shoulder Existing Medical Conditions: None noted Current Medications: None While this question may appear peculiar to those not immersed in niche hobbies, I wanted to seek guidance from medical experts. I have been involved in archery since my teenage years and have recently engaged with the r/Archery community on Reddit. This platform hosts numerous enthusiasts of medieval European and Chinese cultures, many of whom have taken an interest in high-draw-weight warbows and are utilizing historical techniques outlined in ancient manuals and artworks for their training. These bows typically exceed 100 lbs in draw weight. For the past decade, I have been using bows weighing between 40 and 50 lbs; however, I have recently been transitioning towards shooting heavier bows, having started with an 80 lb bow weekly. Lately, I've started to notice some minor discomfort in my left clavicle, particularly where it meets the sternum, and also behind that shoulder. As a precaution, I have refrained from shooting for a week to allow for healing and to avoid potential injury. A few months ago, I consulted an orthopedic specialist about existing joint noises in my bow-side shoulder when I rotate my arm. He assured me that it was not a cause for concern as long as I wasn’t experiencing pain or weakness. My primary worry is not about an immediate or severe rotator cuff injury, as I take a cautious and methodical approach to training. Instead, I’m interested in understanding whether the long-term use of these heavy bows could lead to joint issues as I age. It is my wish to continue practicing archery with my children and grandchildren in the future. While some experienced archers on the subreddit claim that one can manage the risks without problems, I also hear accounts from bowhunters who have undergone surgeries from using heavy bows and suffering shoulder damage, even with weights below 100 lbs. Admittedly, the shooting technique is distinct, involving a considerable forward lean and anchoring the bow arm scapula against the spine, but I aim to ensure that my current practices won’t hinder my ability to engage in archery as I get older.
