Is Leg Shaking in My 4-Year-Old a Cause for Concern?
A 4-year-old girl, Caucasian and weighing 45 pounds, is under no medication and has no significant health concerns at present. I apologize for the poor quality of the video; the positioning was awkward as she was lying in my lap. Every night, she engages in this leg shaking for approximately half an hour before she falls asleep. Initially, I thought it was a charming and comforting behavior, but it now appears to have escalated in intensity. Could this be indicative of restless leg syndrome, and how could I determine if that is the case? In essence, should I be worried about this behavior?

The leg shaking you're observing in your daughter could be a common behavior known as "periodic limb movement" during sleep or possibly an early sign of restless leg syndrome (RLS). While it's understandable to feel concerned, let’s break this down to help you determine if further action is needed.
What You Should Know:
- Leg Shaking in Children: It's not uncommon for children to exhibit leg shaking or movements as they settle down to sleep. For many, this can simply be part of their sleep routine and may not indicate any underlying issue.
- Restless Leg Syndrome (RLS): This condition is characterized by an uncontrollable urge to move the legs, usually accompanied by uncomfortable sensations. It often worsens when at rest and improves with movement.
Key Considerations:
- Time and Context: Since this has been occurring nightly for half an hour, it's worth noting any patterns—such as if it always happens at the same time, if she seems distressed, or if it's only when she’s settling down for bed.
- Behavior During the Day: Observe if she appears restless or has difficulty sitting still during the day, which can also be associated with RLS.
Next Steps:
- Keep a Journal: Track the leg shaking episodes—note the duration, times, and behaviors associated with them. This can provide valuable insights over time.
- Evaluate Comfort: Ensure she’s comfortable before bed—try a consistent bedtime routine, comfortable sleep environment, and avoid any stimulating activities close to bedtime.
- Monitor Symptoms: If she exhibits other signs such as excessive daytime sleepiness, irritability, or complaints of leg discomfort, these could indicate a need for further evaluation.
- Consult Resources: If your observations raise concerns, consider reading about RLS through reputable sources like the National Institutes of Health (NIH) or pediatric sleep associations for deeper insights.
Most cases of leg shaking, especially in young children, are benign; however, keeping an eye on any emerging patterns or additional symptoms is prudent. You’re doing a great job by being attentive to your daughter's behavior, and keeping track of these details will help in assessing whether further action is necessary in the future.

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
