Persistent Swollen Lymph Node After Mono: What Could It Indicate?
For several months now, I’ve been experiencing a swollen lymph node on my neck. While it's not particularly hard, it does cause discomfort occasionally. It’s worth mentioning that I became aware of this node after recovering from mononucleosis, leading me to wonder if it might have existed previously. During my bout with mono, I had noticeably enlarged lymph nodes, but this particular one has remained significant in size and is still movable. I underwent an ultrasound, and the results came back normal. Can anyone shed some light on what this could mean and the reasons behind its persistence?

It's understandable to feel concerned about a persistent swollen lymph node, especially following an illness like mononucleosis. Persistent lymph nodes can result from several reasons, including post-viral changes, immune system activity, or sometimes benign conditions. Given that you've had an ultrasound with normal results, it's encouraging, but let's break this down.
Main Points:
- Swollen lymph nodes after mononucleosis can persist due to various benign reasons like inflammation or immune system activity.
- It's essential to monitor the lymph node and any accompanying symptoms.
Explanation:
After recovering from mononucleosis, it's common for lymph nodes to remain enlarged for a while due to ongoing immune responses. The fact that your lymph node is movable and not hard is reassuring since these characteristics typically indicate that it's less likely to be serious. Lymph nodes may stay enlarged due to inflammation, even after the infection has resolved, as your body continues to clear the remnants of the virus or react to other triggers such as allergies or stress.
Next Steps:
- Monitor Changes: Keep an eye on the lymph node for any changes in size, firmness, or pain levels. Also, note if you develop any new symptoms such as fever, night sweats, or drastic weight loss.
- Self-Care: Maintain a healthy lifestyle that supports your immune system: eat well, stay hydrated, get enough sleep, and manage stress.
- Reassess Regularly: If the lymph node does not improve over the next few months or if you develop new symptoms, consider discussing these changes with a healthcare professional for further evaluation.
Your feelings of discomfort and worry are valid, and monitoring your symptoms is a proactive approach. If anything changes significantly, take that as a cue to reassess your situation. Remember, persistent lymph nodes post-viral infections are generally common and often resolve over time.

Persistent Neurological Disturbances in a 26-Year-Old Woman
Age: 26 years; Weight: 121 lbs; Height: 5'6". I am currently on birth control, a multivitamin, and a vitamin D supplement. I consume alcohol occasionally but do not use any illicit drugs. I am experiencing a seemingly unending sensation of vibration in my head and eyes, accompanied by various other neurological issues. Whenever I shift my gaze, objects appear to waver or shimmer, almost reminiscent of the distortion seen on hot pavement. This is compounded by additional concerns such as trembling hands, balance difficulties—not only when I walk but also while waiting at a traffic light in my vehicle. My speech often comes out jumbled, I struggle to retrieve words, and understanding song lyrics has become increasingly difficult. Additionally, I've faced significant memory challenges, feeling the weight of both short-term and long-term forgetfulness. I frequently endure sharp pains radiating from my neck to my jaw and ear, find it hard to fall asleep, and wake up feeling exhausted, leaving me fatigued during the day. Concentration is elusive, and I find it challenging to process new information. Mood fluctuations are prominent, and I often sense that I can't breathe deeply or feel rejuvenated. Over the years, these symptoms have intensified, rendering basic daily activities and work tasks quite daunting. An MRI revealed some hyperintensities that are thought to have a vascular origin, likely indicating small vessel disease. The doctor noted that these lesions are scattered throughout my subcortical white matter, yet I can’t help but feel that my age was overlooked in this diagnosis, as this condition is more commonly associated with older individuals. The implications of these findings remain unclear to me. Here are some recent blood test outcomes: - LDL Medium: 365 nmol/L - LDL Particle Number: 1,733 nmol/L - LDL Pattern: B - LDL Peak Size: 215 Angstroms - LDL Small: 382 nmol/L - LDL-Cholesterol: 102 mg/dL (calculated) - Cortisol: 39.2 mcg/dL - ANA positive As for my thyroid and iron levels, they have consistently shown normal results over the years. I cannot persist in this state where everything feels in constant flux.
Left-Sided Chest and Back Discomfort
At 28 years old and having experienced arrhythmia in the past, I've had some chest discomfort. Fortunately, after undergoing a battery of tests, my doctor deemed it non-serious, suggesting that we keep an eye on it instead. Although I struggle with my weight, I've made significant strides over the past six months, successfully shedding 35 pounds through regular exercise. Recently, however, I've been struck by an unexpected sharp pain in my left pectoral area. This sensation is more intense than what I've previously felt and tends to arise specifically when I'm standing; it alleviates quickly—within minutes—if I sit or lie down. If I remain upright, the pain can persist anywhere from 10 to 30 minutes, particularly when I first stand up. Interestingly, I don’t experience discomfort when applying pressure to the area. Starting yesterday, I've noticed this chest pain alternating with discomfort in my back. The pain in my back feels sharper, and unlike the chest pain, it affects me even while seated and tends to linger far longer. I have appointments scheduled with my cardiologist and primary care physician in two months; however, I’m contemplating whether this recent development warrants an earlier consultation. While the pain can be quite bothersome, the relief I find when I sit or lie down makes it somewhat tolerable for now.
Intermittent Blood in Stool Concerns

Concerns About My Son's Visible Leg Veins
My son, a 6-year-old boy weighing 38 pounds and of slightly below-average height, has been experiencing something unusual with his health. He does not have any known medical conditions and is not on any medication — we reside in the USA. I've observed that several veins on his right leg appear quite prominent. These veins look normal in structure; they are straight and elongated, with no visible tangling. There’s a noticeable long vein on the back of his thigh and what seems to be two additional veins running along his inner calf. Instead of a color change, what stands out is their protrusion—they are raised enough to cast a faint shadow when light hits them a certain way. It's reminiscent of the vascularity seen in bodybuilders, yet this is occurring on a rather slender 6-year-old. He has expressed no discomfort and behaves just like any other child his age, although he has always been on the lower side of the weight spectrum. My mother had experienced varicose veins, and I’ve also developed mild varicose veins in my youth, though my symptoms manifested more prominently and in a twisted manner, unlike my son's. His situation feels particularly concerning due to his young age and the difference in how the veins appear. The pediatrician has scheduled an ultrasound for further evaluation, but I find myself anxious as we await the appointment. I'm reaching out to see if anyone has encountered similar experiences or understands what may be happening with my son’s veins.
At 29, I'm Experiencing Severe Symptoms Often Linked to Sinus Cancer, but My Doctor Refuses to Refer Me
As a 29-year-old former smoker, I have developed four noticeable lumps on the right side of my face. One is located beneath the brow bone, near the corner of my right eye, while another is situated just below it, under the eye. Additionally, I have two lumps at the base of my skull on the right side. Each of these lumps is sensitive to touch and the pain often radiates to the adjacent ones upon contact. Tactile stimulation also triggers watering of my eyes and causes my nose to run. I've been experiencing bulging and watering in my right eye as well. The lymph nodes in my throat tend to be consistently swollen; I frequently cough up bloody mucus and struggle with my breathing. To add to my concerns, I'm also noticing pain radiating through my upper teeth as well as some loss of hearing on the right side. I have brought these symptoms to my GP's attention. Despite the obvious tenderness of the lumps, my doctor ordered an X-ray, which surprisingly did not reveal anything unusual. Given my young age, she dismissed the notion of cancer, suggesting instead that I merely have persistent swollen or irritated sinuses. These lumps have been present for several months and have even increased in number since they initially appeared. Is it plausible that all these symptoms are merely coincidental? Can individuals genuinely live with such ailments and endure these tender bumps in their sinus regions indefinitely? Unfortunately, I can't change my GP here in my country.
