Understanding Thyroid Health
Greetings! I'm a 58-year-old woman, and I recently underwent a thyroid blood test. The results for TSH, T3, T4, TPO, and TG were all within the acceptable range. However, I was surprised to find that my Thyroglobulin level was elevated at 91 ug/L, where the typical upper limit is 44. From what I gather, the Thyroglobulin test is often utilized as a tumor marker for thyroid cancer, particularly in patients after surgical treatment. I sought these tests because I've been experiencing various symptoms including extreme fatigue, excessive sweating, difficulty tolerating heat, and stiffness and pain in my joints. The most challenging issue for me is the profuse sweating and sensitivity to heat, which severely affects my daily life, especially since I live in a region with high humidity. This uncomfortable condition persists throughout the year, even in air-conditioned environments, making it quite unbearable. As I’m post-menopausal, I’ve ruled that out as the cause since these sensations feel distinctly different. Additionally, I've noticed that the left side of my neck has become quite firm and rigid, although it’s not causing me any pain. I'm curious whether this could potentially signify Thyroiditis. Would you suggest further investigations? An ultrasound might be necessary, I assume? Have you encountered similar cases in your experience? For your information, my C-reactive protein (CRP) level is recorded at 12. These symptoms have persisted for quite some time, and the firmness in my neck has also been ongoing. I'm uncertain if there’s a relationship between the hardness in my neck and the elevated Thyroglobulin level. Just a heads up: I’ll be consulting with a general practitioner soon to discuss these concerns further.

Main Points: Your elevated Thyroglobulin level and firm neck area, along with your symptoms of fatigue, sweating, and joint issues, warrant further investigation. It's good that you're seeking expert input from your general practitioner, as additional tests may help clarify the situation.
Explanation: Thyroglobulin is a protein produced by the thyroid gland, and while it can be a tumor marker for certain thyroid cancers, it can also be elevated in cases of thyroiditis or other thyroid disorders. Given your symptoms of extreme fatigue and excessive sweating—combined with the firm area in your neck—these may suggest possible thyroid issues, such as autoimmune thyroid disease (like Hashimoto's thyroiditis), or even nodular changes in the thyroid gland.
With your C-reactive protein (CRP) level being elevated at 12, there may also be an inflammatory component at play. The firmness in your neck could indicate an enlargement or nodularity of the thyroid gland, which often requires further imaging.
Next Steps:
-
Discuss Imaging Tests:
- Confirm with your general practitioner whether an ultrasound of the thyroid is appropriate. This can help identify structural changes such as nodules or inflammation.
-
Monitor Symptoms:
- Keep a symptom diary detailing your fatigue, sweating episodes, any changes in the firmness of your neck, and joint pain. This information can be valuable during your consultation.
-
Consider Additional Blood Tests:
- Ask your doctor about potential follow-up tests, such as thyroid antibodies and possibly a thyroid scan, which might provide a clearer picture of your thyroid function and health.
-
Lifestyle Adjustments:
- To manage your symptoms in the meantime, focus on staying hydrated and wearing breathable clothing, which may help reduce discomfort due to sweating in humid conditions.
By addressing these steps with your doctor, you can work toward understanding the root cause of your symptoms and find an effective management plan. Let me know if you have further questions or need additional details!

Strange Jelly-Like Substance Observed from Wound
I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.
Battling Chronic Nausea and Vomiting for Over Two Years
For the past two years, I (age 26, female) have been enduring an incredibly challenging health situation. I experience intense nausea daily and find myself vomiting numerous times, with almost nothing providing relief. To provide some background, I’m from West Texas and I currently weigh around 190 pounds, standing at 5’7”. Initially, my weight was about 211 pounds when these symptoms began, and it fluctuates frequently between 190 and 225 pounds. I engage in vaping and consume THC. Previously diagnosed with hypothyroidism, my condition seemingly resolved, according to my healthcare providers. Additionally, I have polycystic ovarian syndrome (PCOS). I have consistently faced irregular bowel movements, with stools that are loose and sometimes appear to have mucus. Compounding my struggles, I've also suffered from migraines. I have had an IUD for over five years, experiencing two insertions of the Kyleena device. In December 2022, my battle with health took a severe turn when I was diagnosed with stage 4 Hodgkin’s Lymphoma, requiring chemotherapy treatment, specifically AVBD (Apologies for not recalling the exact medication names). By July 2023, I had fortunately achieved remission. However, after reaching remission, my vomiting worsened, transforming from primarily white foam to a mixture of 80% bile, any food I attempt to consume, and still white foam. This intense vomiting, accompanied by significant pain in my upper back, escalated to more than eight episodes daily by November 2023. At that time, THC seemed to be the only avenue for me to retain any food. During this tumultuous period, I consulted various doctors who, after confirming I wasn’t pregnant, attributed my symptoms to Cannabinoid Hyperemesis Syndrome (CHS). Immediately, I ceased THC consumption for over six months, yet the vomiting continued unabated. Each time, doctors would prescribe ondansetron, regardless of my claims that it provided no relief. I experimented with various diets recommended by medical professionals, but there were no improvements in my condition. Eventually, I obtained a referral to a gastroenterologist who intended to perform an endoscopy. However, the procedure was prohibitively expensive even with insurance, and thus was never conducted. This doctor also ordered blood tests to rule out several gastrointestinal disorders, such as Crohn's disease, Irritable Bowel Syndrome (IBS), and gluten sensitivity, but all results came back normal. Afterward, I had another appointment with a different gastroenterologist, but the doctor failed to meet with me. Instead, a nurse informed me that the doctor had merely recommended promethazine without conducting any tests or scheduling further visits. When I mentioned the possibility of gallbladder issues, the doctor laughed dismissively at my suggestion. Discussing my situation with my oncologist, he suggested that my heightened sensitivity to food odors stemmed from my chemotherapy experiences while I was working in fast food. While food smells indeed affect me, I'm primarily triggered by medical scents such as rubbing alcohol and cleaning agents. This ongoing ordeal has been overwhelmingly distressing. I now experience episodes of vomiting accompanied by bright red blood, presumably due to a throat tear. When I first encountered this troubling symptom, I consulted a doctor who appeared unfazed and prescribed a promethazine suppository, which does help but makes me extremely drowsy. My nausea persists nearly around the clock, often feeling as if there’s a heaviness in the upper part of my abdomen. I frequent urgent care facilities when my symptoms intensify, only to be met with minimal assistance since this is a chronic issue. Currently, I lack a primary care physician. Whenever I sought one, I encountered skepticism regarding my condition, with some healthcare professionals implying that I was exaggerating my symptoms. Though many physicians who do take my situation seriously seem baffled, I've lost count of the diverse medical experts I've consulted about these ongoing issues. If anyone has insight or suggestions, I would genuinely appreciate it. I can share my latest bloodwork results if that would be helpful—just let me know!
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
