Seeking Advice on Persistent Arm Discomfort

9/10/2025, 1:10:29 PMMale25-34

I am a 71-year-old woman standing at 5’5” and weighing 130 pounds. Like many of my peers, I deal with the typical health issues associated with aging, including high blood pressure and chronic back pain, along with a history of skin and breast cancer. However, I’ll focus on a minor yet bothersome injury that has caught my attention rather than listing every medication and health condition I manage. I’m looking for some feedback regarding an experience I had with last year’s flu vaccine. Just to clarify, this isn’t a discussion about vaccines in general. Here’s some background: I’ve been receiving the flu shot annually for as long as I can remember, and the usual soreness in my arm would subside within two days. However, last year’s shot felt different. Initially, I thought the discomfort would diminish, but it persisted. The discomfort manifests as muscle pain when I lift my arm, especially noticeable when I’m turning the steering wheel while driving, and it also occurs during everyday activities that require reaching. While the pain has not compelled me to seek medical advice, it’s irritating enough that I suspect the injection may have injured the muscle. Remarkably, the discomfort has remained consistent over the year; it flares up during specific movements but neither worsens nor improves. I’m not experiencing pain in the shoulder joint or around it; my shoulder has full range of motion without any issues. The pain, which seems to originate in the outer upper arm (perhaps the deltoid?), began immediately after receiving the flu shot. Based on my understanding, it doesn't appear to be SIRVA, given the symptoms I’ve read about. I only feel discomfort when my arm is raised; at rest, it’s fine. As my next flu vaccine is approaching, I’m in a bit of a quandary; I cannot use my other arm for the shot due to a previous mastectomy. Thus, I’m curious whether it’s prudent to get vaccinated in what might be a compromised muscle, or if I should proceed without concern. If necessary, can they administer the shot at a different site if I request it? Also, should I focus on this muscle pain more seriously, or is it best to continue managing it as I have been? While it’s not debilitating, I’d rather not see it worsen. I appreciate any insights you can provide!

It's important to address your concerns regarding your persistent arm discomfort and the upcoming flu vaccine. You're right to be cautious, especially given the history of discomfort you’ve described after last year’s flu shot.

Key Points:

  1. The discomfort you're experiencing may relate to the vaccine site, but it doesn't sound typical for SIRVA (Shoulder Injury Related to Vaccine Administration).
  2. You should consider discussing alternative vaccination site options and managing current discomfort before receiving the flu shot.

Explanation:

Typically, soreness after a vaccination can last a few days. However, persistent muscle pain a year after the shot could indicate strain or irritation in the area where the injection was given. The muscle pain you're feeling when lifting your arm may result from overuse or minor muscle injury, especially since you mention it only happens during specific movements. Because your shoulder range of motion is intact and you're not experiencing joint pain, this supports that the issue may be muscular.

Next Steps:

  1. Assess Pain Management: Continue to manage the discomfort as you have but consider incorporating gentle stretching exercises targeting the deltoid and upper arm muscle over the next few weeks, paying attention to your body's response.

  2. Talk about the Vaccine: When it's time for your flu shot, discuss your pain with the healthcare provider. Ask if they can administer the vaccination into an alternative site, such as the upper thigh, which is often an acceptable option if there are concerns about the usual site.

  3. Monitor Symptoms: Keep track of any changes in pain levels or function over the next few weeks. If the discomfort worsens or starts affecting your daily activities more significantly, consider seeking medical advice to explore further options like targeted physical therapy or specific exercises.

  4. Stay Informed: Be prepared with information from your healthcare provider about the potential for persistent discomfort from vaccinations. Knowing what to expect can help you make informed decisions each flu season.

It’s reassuring that you're aware of your body's signals. If you have further questions or concerns, feel free to reach out for more support.

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?

Assessing My Health Concerns: How Anxious Should I Be?

I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.

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.
