Unexpected Forearm Swelling: What Could It Be?
Hello everyone, I wanted to share my experience from today. Earlier, I felt some discomfort in my left arm, similar to what one might feel after an intense workout or from an awkward motion, so I didn’t think much of it. I just assumed I might have slept on it awkwardly. However, about half an hour ago, I touched my hand and found that it felt unusually soft and somewhat squishy. To my surprise, I noticed significant swelling. The swelling appears to start midway along the back of my forearm and extends down to my hand, with a noticeable indentation at the wrist, which seems to be from movement. Moving or rotating my forearm brings discomfort, and the swollen area is quite tender when I press on it. I'm fairly certain I may have either sprained or strained my arm (although I can’t quite differentiate between the two). I made the mistake of asking a chatbot for advice, and it suggested the possibility of a blood clot, which has me a bit worried. At 23 years old, while I do smoke and take various medications for Crohn's disease (and I am attempting to quit smoking), I find it hard to believe that I could be dealing with a blood clot. It's currently 1 AM here, and I’m letting my anxiety get the better of me. I'm not a fan of going to the emergency room, hence wanting to reach out to the online community instead. In conclusion, dear Reddit, am I facing a serious health issue or am I just succumbing to late-night anxiety about my health?

It sounds like you’re understandably concerned about the sudden swelling in your forearm, especially given your medical history and the time of day. Swelling and tenderness can stem from various causes, including a sprain, strain, or even an inflammatory response due to an underlying condition. While blood clots are a possibility that shouldn’t be dismissed, they are less common in a young person without risk factors.
Explanation
-
Causes of Swelling: Common reasons for forearm swelling include:
- Sprain or Strain: A mild injury to muscles or ligaments can cause localized swelling and discomfort.
- Tendonitis or Bursitis: Inflammation in the tendons or fluid-filled sacs can also lead to pain and swelling.
- Infection: Although less likely, infections can lead to swelling and tenderness.
- Blood Clot: This usually presents with warmth, redness, and can cause pain, but it’s not the most likely cause given your age.
-
Your Concerns: The anxiety you’re feeling is normal, especially when experiencing unexpected symptoms. Smoking can complicate health situations, but many active young people with similar habits face challenges like this.
Next Steps
-
Self-Care:
- Rest and Elevate: Try to keep your forearm elevated above heart level to help reduce swelling.
- Ice Application: Apply an ice pack wrapped in a cloth to the swollen area for 15-20 minutes every hour, as it can help decrease swelling and discomfort.
- Compression: If safe and comfortable, consider using a compression bandage to support the area.
-
Monitor Symptoms:
- Keep track of the swelling, pain levels, and any changes. Note if you develop new symptoms like fever, increased pain, or changes in color of the skin around the area.
-
When to Seek Medical Attention:
- If the swelling increases significantly, or if you experience severe pain, warmth, redness, or any symptoms indicative of a blood clot (like swelling in the calf or thigh, sudden shortness of breath, or chest pain), seek medical help promptly.
Final Thought
Pay attention to your body, and perhaps consider scheduling a non-urgent appointment with a healthcare professional in a few days to discuss your symptoms and any ongoing concerns, especially considering your autoimmune condition and smoking habit. Take care, and try to address your anxiety with calming strategies; you're doing the right thing by seeking information and support.

How to Manage Bleeding Hands?
During the winter months, I often experience extreme dryness in my hands that leads to cracks and bleeding. I've experimented with various remedies, including O'Keefe's, Vaseline, and corn huskers. I’ve also tried wet wrapping, where I apply Vaseline and cover my hands with socks or gauze, and a few steroid creams for eczema, which helped soothe some itchy patches but did little for the severe cracking and bleeding that is causing discomfort. Currently, I am prescribed budesonide and mesalamine (Apriso at the usual dosage) and am recovering from a Crohn's flare-up. I recently took prednisone and some gastrointestinal treatments (thankfully avoiding biologics for now), but I feel exhausted. My hands are becoming rough and sandpaper-like, and while I know it sounds dramatic, both mentally and physically, I need my body to ease up. Additionally, I’m dealing with an annoying ear boil and need to use ear drops; I frequently suffer from itchy ears that sometimes lead to these boils. I'm on a tight budget, especially after incurring significant expenses related to my flare-up. Is there anything I might have overlooked that doesn’t necessitate a doctor's visit? Alternatively, how can I prevent my hands from getting infected if washing them exacerbates the situation while my body recuperates? Thank you for your help.

Exploring the Connection Between Persistent Eardrum Issues, Nasal Congestion, and Recurring Illnesses
Age: 21. I have experienced chronic nasal congestion since I was a child. While I don't typically exhibit classic allergy signs like sneezing or itchy eyes, I generally find my nose to be somewhat blocked most of the time. On January 23, I was evaluated for a bulging eardrum on one side, an issue that has recurred multiple times in the same ear. Following that visit, I was advised to use Flonase and Zyrtec, which provided some relief. However, once I ceased using them, the problem reappeared. Additionally, I frequently come down with what I would describe as “colds.” The pattern of my symptoms is quite consistent: - Day 1: constant throat clearing paired with fatigue. - Days 2 to 4: feelings of feverishness, chills, and lightheadedness. - This is followed by a sore throat, cough, and significant nasal congestion that tends to linger. These episodes occur several times each year, often persisting longer than they seem to for others. I’m curious if there’s a recognized chronic pattern associated with these symptoms?
Managing Iron Deficiency During Early Pregnancy Post-Gastric Bypass
A 33-year-old female, currently 4 weeks and 2 days pregnant, is experiencing iron deficiency anemia after having undergone Roux-en-Y Gastric Bypass surgery 2.5 years ago, which resulted in a weight loss of 150 pounds, bringing her BMI to approximately 29. As a vegetarian, she frequently feels fatigued and lacks energy, which she initially attributed to her history with weight loss surgery. To help address her nutritional needs, she has been taking Bariatric Advantage Chewable Multivitamins containing 45mg of iron (in the form of ferrous fumarate), which provides 250% of the daily recommended value. However, her primary care physician initially suggested administering Venofer in 200mg doses across four sessions. With her recent pregnancy, she is now uncertain about the best approach for her health and her baby's development, particularly considering her background of gastric bypass. Recent lab results indicate significant iron deficiency: - Ferritin: 4 (very low) - Iron: 40 (low) - Iron Binding Capacity: 531 (high) - Iron Saturation: 8 (low) - Transferrin: 379 (high) - Red Blood Cell Count: 4.53 - Hemoglobin: 11.6 (low) - Hematocrit: 36.4 - MCV: 80.5 (low) - MCH: 25.7 (low) Other blood tests for B12 (550), folate (>20), and vitamin D (30) returned normal levels, further complicating her management of iron deficiency. She seeks advice on navigating her condition effectively during pregnancy while optimizing for both her well-being and that of her developing child.
Inquiring About Compression Socks After Injury
Hello everyone, I have a somewhat unusual inquiry. To provide some background, I recently visited urgent care due to worries about a possible Achilles tendon injury. A physician evaluated my condition and confirmed there was no tendon rupture. Currently, I'm awaiting a callback from the sports medicine team for additional assessment, as the initial doctor was unable to perform the necessary imaging to determine if there is a partial tear. In the meantime, she provided me with a supportive brace that has been quite beneficial. After removing the brace for a while to let my skin breathe, I experienced some issues with circulation, which tend to happen to me, particularly during my menstrual cycles. Therefore, I’m curious if it’s advisable to wear my compression socks as I typically do, or if I should wait until a definitive diagnosis regarding the potential tear is made. Thank you in advance for your insights!
Seeking Advice on Persistent Hand Cracking and Cuts
My mother is experiencing a troubling condition affecting her hands, characterized by significant cracking and wounds that do not appear to be the result of any injury. This issue has persisted since December, and while both hands are affected, one hand shows more pronounced symptoms. After consulting with her doctor previously, she was given a cream that initially seemed to provide some relief, but the problem recurred. Now, she has returned to the doctor and is currently using another type of medical ointment. I'm looking for a casual assessment of her situation. Could this be indicative of a severe form of eczema?
