Is It Possible I Restricted Blood Flow to My Brain While Sleeping?
Age: 23, Male I have a peculiar situation to share. This morning, I woke up after just four hours of sleep, having ended up sleeping on my stomach with both arms positioned underneath me. As a result, both arms became numb, which I found unusual since I’ve only experienced this with one arm previously. When I shifted to my side and blood flow returned to normal, I felt a sensation similar to that of a limb waking up—but this time, it was localized on the left side of my head, in the parietal region. Since that moment, I haven’t noticed any significant issues, apart from a persistent headache that has lingered throughout the day. I recognize that I might be overreacting, especially considering it’s about my head, but I feel the need to exercise caution. Is there a possibility that I inadvertently restricted blood flow to my brain while sleeping in that position?

It's understandable to feel concerned after experiencing numbness and a persistent headache. The symptoms you're describing are likely linked to the position you slept in, which can compress nerves and temporarily restrict blood flow to certain areas.
Explanation
When you sleep with both arms underneath you, it can compress nerves not just in the arms but also potentially affect blood circulation. This is common and typically resolves quickly once you change positions, as it appears happened when you moved to your side. The sensation of your body part "waking up" and the headache you experienced could be your body's response to the pressure being released.
For most people, these symptoms aren't alarming, especially if they resolve quickly. However, since you're noticing a headache that lingers, it's wise to pay attention to it. Headaches can be caused by many factors, including sleep position, stress, dehydration, or even muscle tension.
Next Steps
- Monitor Symptoms: Keep an eye on your headache. If it starts to improve throughout the day, it’s likely nothing serious.
- Hydrate: Drink plenty of water today, as dehydration may contribute to headaches.
- Rest: Try to relax and avoid any strenuous activities. A calm environment may help your headache dissipate.
- Adjust Sleep Position: In future, consider avoiding sleeping on your stomach with your arms under you. Finding a more neutral position, like sleeping on your side with a supportive pillow, may help prevent similar occurrences.
- Pain Relief: If the headache persists or worsens, consider taking over-the-counter pain relief, such as ibuprofen or acetaminophen, following the recommended dosage.
If you continue to experience headaches or develop new symptoms such as visual changes, dizziness, or significant pain, please seek medical advice to rule out any underlying issues. Remember to listen to your body’s signals and take care of yourself!

Experiencing Heavy Bleeding After IUD Removal
Hi there, I recently had my Liletta IUD taken out on Tuesday, and since August 18, I have been experiencing intermittent heavy bleeding. Today, I passed a blood clot resembling jelly, about the size of my palm, which left me quite stunned. Within a span of two hours, I had to use two ultra tampons due to the heaviness of the flow. Thankfully, the bleeding seems to be gradually decreasing, and I'm making sure to stay well-hydrated. After undergoing an ultrasound, it was revealed that my IUD was positioned lower than it should be, and I also have a uterine fibroid. The dimensions of the fibroid are 4.6 cm x 4.7 cm x 4.7 cm, located on the right fundal area, intramural/subserosal. In our discussion, the OBGYN nurse practitioner suggested that I consider having a new IUD inserted, despite it previously shifting out of place, although she couldn't provide a clear explanation for that occurrence. The insertion process is quite distressing for me, so I don't make this choice lightly; however, living without my period significantly improves my quality of life. Since the removal, I've started bleeding again, and I'm feeling extremely unwell, particularly today. Is the heaviness of my bleeding particularly concerning because it's following the removal of the IUD, or should I expect this as my new normal? Considering the presence of the fibroid and my current results, what advice can you offer? I have an appointment set with a family planning specialist this week and will meet with a fibroid expert next month; I want to explore my options thoroughly. Am I being overly dramatic in contemplating a hysterectomy? I've never desired children and do not plan to have any in the future. Initially, I anticipated only a brief return of my period after the IUD was taken out, but bleeding has persisted for nearly a month, much heavier than I expected. Any suggestions on what questions to pose to my doctors would be greatly appreciated.
Desperate for Answers After Multiple Medical Visits
I have been experiencing what can only be described as a challenging few months filled with anxiety, particularly concerning the fear of having pancreatic cancer. To provide some context, my dental health is quite poor; my teeth are essentially in decay. I have been a heavy nicotine vaper for around eight years, and I consumed alcohol daily for about four years, typically limiting myself to 2-3 drinks each evening. I ceased drinking entirely once my symptoms emerged. Interestingly, my symptoms began shortly after I underwent wisdom tooth extraction. The symptoms have been extensive, but the most alarming changes include a significant weight loss of 30 pounds in just one month, coupled with noticeable muscle atrophy. I also experience intermittent pain in the left upper quadrant of my abdomen, accompanied by variable swelling. Furthermore, I have been dealing with steatorrhea, characterized by oily, yellow stools and pale coloration, which has shown some improvement since I started taking Creon prescribed by my doctor. I've noted pain in my left testicle, which mirrors the discomfort in my abdominal area. Throughout this ordeal, I've been experiencing widespread muscle aches on and off. Additionally, I have swelling in the glands located under my chin and jawline, as well as a potential small swelling in the back upper part of my neck near the hairline. I constantly feel the urge to urinate, accompanied by bright yellow, warm urine, and an unending thirst. My blood tests have generally come back normal, with the exception of slightly elevated segmented neutrophils and bilirubin levels. I have undergone a series of CT scans, including one for my abdomen and pelvis which yielded no conclusive results, as well as one for my head and neck that revealed only a mucous retention cyst in the right maxillary sinus and a tracheal diverticulum without fluid accumulation. An ultrasound of my testicles also returned normal results. An upper endoscopy conducted by a gastroenterologist showed no abnormalities. Despite visiting five emergency rooms and maintaining daily communication with my family physician, I feel utterly lost and on the brink of despair. I am currently waiting for MRI insurance approval and find it hard to manage my worries and anxiety during this uncertain time. I would appreciate any advice or insights regarding my situation as I continue to search for answers.
Bump Beneath the Left Rib Area
At 24 years old, I recently noticed a bump located beneath my left rib cage. It doesn’t hurt, and while it’s not overly stiff, it certainly feels firm to the touch. Visually, it’s not readily apparent, but I can easily detect its presence when I run my fingers over the area. Alongside this, I’ve been experiencing significant fatigue lately, though I’m uncertain if this is connected to the lump or merely a result of stress I’ve been under. Should I be concerned about this, or is it possible that I’m overreacting and it’s simply a part of my stomach that I’m feeling instead?
Should We Head to Urgent Care for Our Baby's Eye Irritation?
A few details: our baby boy is 5.5 months old, approximately 26 inches tall, and weighs around 17 pounds. Main concern: his eye has become irritated following an incident where it may have been scratched or poked (we're uncertain about the exact cause). Hello, [r/AskDocs](https://www.reddit.com/r/AskDocs)! Earlier this evening, around 5 PM, our little one scratched (or poked) his eye. Although I wasn’t a witness to the event, I heard him cry for about 30 seconds to a minute, after which he calmed down and contentedly finished his bottle. Since then, however, his eye has remained red and excessively watery for about an hour and a half to two hours leading up to bedtime. Initially, we weren't overly concerned, but a brief online search left us questioning whether we should take him to urgent care this evening to have a professional examine him for a possible scratch, or if it would be acceptable to wait and see how things look by morning.
Unexplained Sharp Pain in the Left Side of My Back
I’m a 38-year-old man, standing at 5 feet 10 inches tall and weighing about 13.5 stones. Although I carry a bit of extra weight, I’m not classified as obese. I maintain an active lifestyle by walking regularly and engaging in various sports. I experience an intermittent, intense shooting pain located on the upper left side of my back, close to my left armpit. To clarify, the discomfort resides in an area that is quite challenging to reach; I cannot easily scratch it with my right arm. To alleviate the itch, I have to stretch significantly from the front and lift my left arm, which hopefully paints a clearer picture. This pain surfaces primarily during physical activities—such as while playing sports, especially after jumping and landing, or when my left arm is extended. Additionally, it occurs when I lie down and take deep breaths. When I inhale deeply, I feel a sharp pinch that results in excruciating, fleeting agony lasting a couple of seconds before subsiding. I suspect this might be related to a nerve being compressed. My main concern is whether there are any methods to relieve the nerve or if this is merely a temporary issue that should resolve on its own, meaning I shouldn't worry excessively. Thank you for any guidance you can provide!
