Understanding Facial Swelling Post-RAI Treatment

7/29/2025, 5:30:36 PMMale25-34

At 42 years old and having been diagnosed with papillary thyroid cancer, I underwent a complete thyroidectomy in December, followed by treatment with Radioactive Iodine (RAI) in March. Recently, I felt mild discomfort on the left side of my face, and upon waking up, I noticed it was quite painful and noticeably swollen. I am aware that experiencing such symptoms can occur up to a year after receiving RAI, but how can I determine whether this facial swelling is indeed a side effect of the RAI or if it may be attributed to another issue? Should I consult a healthcare professional for a thorough assessment, or can I assume that this is a typical reaction to RAI that will resolve on its own?

Facial swelling and discomfort after undergoing radioactive iodine (RAI) treatment can be concerning, and it’s important to understand the possible causes and what steps you should take. While mild swelling can indeed occur after RAI, your symptoms warrant careful evaluation to rule out other issues.

Explanation

After RAI treatment, some patients may experience swelling or discomfort in various areas due to inflammation, especially around the neck and throat. However, significant or painful swelling in the face can also result from other conditions, such as an allergic reaction, infection, or even lymphatic issues related to surgery or RAI treatment.

Given that this is a new symptom post-treatment, it is crucial to monitor the situation closely. While it’s possible that this could resolve on its own, it’s essential to determine if there are signs of infection (such as increased redness, warmth, or fever) or other complications.

Next Steps

  1. Monitor Symptoms: Keep track of the swelling's progression. Note any changes in size, pain level, or new symptoms (like fever or additional swelling).

  2. Manage Discomfort: Use cold compresses on the swollen area for short periods to help reduce swelling and alleviate discomfort.

  3. Hydrate: Ensure you are staying well-hydrated, as this can help with recovery and overall health.

  4. Consult a Healthcare Professional: Given your recent treatments, it’s advisable to reach out to your doctor to discuss your symptoms. They can assess whether further evaluation or treatment is needed.

  5. Document Your Symptoms: Keep a brief journal of your symptoms, including when they occur and any other relevant details, which can help your healthcare provider in assessing your condition.

Taking these steps will help you better understand your situation and maintain your health post-treatment. Always trust your instincts when it comes to your health; if something feels off, it's worthy of attention.

Seeking Insights on My Dad's Cancer Claims

Greetings, In brief: I have doubts regarding my father’s claim of having "Stage 4 medullary renal carcinoma," especially considering the demographic and genetic factors associated with this specific cancer. I am a 40-year-old woman with a father in his 60s who exhibits narcissistic tendencies and has a history of estrangement from our family. I’d like to know if any oncologists could provide insight into whether my dad might be lying or embellishing details about his condition. For years, he and I have lived apart—over 15 years without visiting home. A persistent problem with substance abuse has characterized his behavior for as long as I can remember. He is known for being a pathological liar, often fabricating stories and living in his own fabricated reality without hesitation. About a year ago, his sister contacted me through Facebook, claiming he requested her to keep his condition confidential. However, she felt compelled to share that he has been diagnosed with kidney cancer. This revelation opened up a dialogue between my father and me, but extracting any detailed information from him has proven to be exceptionally challenging. Eventually, I managed to confirm his diagnosis as "Stage 4 medullary renal carcinoma." Upon researching, I've found that this cancer is extremely rare in Caucasian males of his age, predominantly impacting younger Black males with a sickle cell trait—a condition he does not possess. Furthermore, the prognosis for this type of cancer is notoriously grim, yet it has been about 16 months since I learned about his diagnosis, which seems inconsistent with the typical progression. As an individual currently experiencing my second remission from two hematological cancers—chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL)—I find myself feeling torn. My personal experience with rare cancers makes me more empathetic to his situation, yet it also heightens my sensitivity to the possibility that he may be manipulating the truth. This internal conflict is consuming me. I feel compelled to uncover the truth but am at a loss on how to proceed. There is certainly more to this narrative, but my request is simple: any guidance on how to discern the reality behind his claims would be greatly appreciated. I am willing to engage with his tactics if necessary just to gain clarification. I’m aware of the implications of privacy laws such as HIPAA, but the thought of my father potentially fabricating this illness—and targeting me of all people—is particularly distressing. It feels like a mockery of my own experiences with cancer, and I can't fully express just how troubling it is to question his authenticity. Thank you for your assistance.

Intense Throat Discomfort on the Left Side While Swallowing and Moving My Neck

I am a 24-year-old male, standing 5 feet 7 inches tall and weighing 67 kilograms. For the past two days, I have been experiencing a sharp pain localized in the upper area of my throat. This discomfort intensifies whenever I attempt to swallow. After examining the painful region externally, I found that the outer part of my throat has also begun to hurt. I’ve noticed that my left tonsil appears to be slightly swollen, creating a noticeable difference compared to my right tonsil. The nature of this condition is unclear to me. Although the pain is intermittent, it becomes particularly acute during swallowing. Even when swallowing saliva, it feels as though I am trying to pass a thick substance down my throat. I am feeling quite anxious about my situation and have been struggling to get proper rest. Any assistance or guidance would be greatly appreciated.

Recovery Journey After Plural Tuberculosis and Empyema

A 23-year-old male patient recounts his struggle with respiratory issues that began in January 2025. He experienced severe chest pain and difficulty breathing, leading to a diagnosis of fluid accumulation in his left lung, rendering it invisible on an X-ray. Despite multiple attempts, medical professionals struggled to drain the fluid. His blood results showed a significantly high ESR, along with persistent cough and fever, which necessitated the use of an oxygen tank. Fortunately, over time, he began to show signs of recovery. Currently, he is in the seventh month of his treatment regimen, which includes RCNEX and Benadon, following a three-month course of Mycobutol. However, the toll of anxiety and depression impacted him negatively, particularly in July when he resorted to alcohol consumption, which left him feeling lethargic and low-spirited. Although there remains a small amount of fluid in his lungs, he understands that refraining from alcohol is advisable. His primary concern is to hear from medical professionals about the possibility of fully recovering without remaining fluid in his lungs. Additionally, he battles feelings of loneliness, living away from family during this challenging time.

How to Persuade Your Doctor to Take Rectal Bleeding Seriously

Age: 29, Weight: 154 lbs, Height: 6’ - Canada I’ve been experiencing persistent rectal bleeding, along with itching and discomfort while using the restroom, for quite some time. Despite my repeated requests for further examination, my doctor has yet to take action. I ended up in the emergency room after nearly fainting from the pain, where I learned my symptoms are not related to hemorrhoids, as I don’t have them. They confirmed I tested positive for HSV type 1, and I was prescribed Valtrex for treatment. However, the bleeding, along with mild pain and itching, continues to trouble me. This has been going on for months! I keep returning to my doctor, who promises to order a fecal calprotectin test, but the weeks turn into months with no follow-up. On one occasion, I noticed bloody tissue during a restroom visit. When I informed my doctor about this, he reluctantly agreed to refer me to a gastroenterologist. However, there's been no colonoscopy scheduled, no blood tests conducted, and it feels like I’m going crazy with worry! I’m hoping to start a family soon, but this issue remains unresolved, making me feel stuck. I truly need some advice or insight! For context, there is no family history of cancer, but there is a history of Crohn's disease in my family.

Injury Update: Glass Cut on Hand

On Friday at around 1 PM, I sustained a cut on my hand from a shard of glass while handling it. I’ve chosen not to seek emergency medical attention due to financial constraints, as I do not have insurance. I am a 37-year-old male, standing 6 feet 3 inches tall, weighing 300 pounds, and I’m currently not on any medication, nor do I smoke. My medical history is clean with no prior conditions. The incident occurred four days and seven hours ago, and although the cut initially seemed deep—it punctured my skin about 0.75 centimeters—it has mostly healed on the surface since then. However, I’m experiencing some discomfort. Since the injury, my middle and right fingers have developed a cramping sensation in the lower middle part of each finger. It feels as though I need to stretch or pull them, but I find no relief from the sensation. There is only mild pain when I touch the area of the wound, which still feels slightly tender. My concern grows, as I’m apprehensive about the possibility of long-term pain due to this injury. I regret not seeking help from a hospital, but again, affordability is a significant issue for me. I’m left uncertain about what my next steps should be to address this health concern without incurring excessive medical costs.
