Concerns After FESS Surgery: Is the Infection Serious?
Greetings, Three weeks ago, I underwent Functional Endoscopic Sinus Surgery (FESS), and one of the sites treated was the ethmoid region. For the past week, I noticed an increase in the production of green mucus, significantly more than what I had experienced previously. I consulted with a physician today, and it turns out I have developed an infection in the ethmoid area, for which I have been prescribed antibiotics. My primary concern stems from the fact that about a week ago, coinciding with the onset of the infection, I was given a course of corticosteroids. These medications are known to suppress the immune system, and I only discontinued the corticosteroid nasal spray today. I am experiencing green, foul-smelling mucus, along with a mild headache—potentially due to dehydration, although that's not certain. Additionally, for the past few days, I have noticed the presence of blood in the mucus, albeit today the situation seems slightly improved. Given these symptoms, I am anxious about how severe my condition might be. Should I be particularly alarmed about the risk of brain damage? For an entire week, I have been inhibiting my immune response in an area where infection could easily reach the brain. Thank you for your guidance.

It’s understandable to feel anxious given your recent surgery and current symptoms. You are experiencing increased mucus production, a foul smell, mild headache, and some blood in the mucus following your Functional Endoscopic Sinus Surgery (FESS).
Key Points:
- You are recovering from surgery and have developed an infection.
- You've recently used corticosteroids, which can affect your immune response.
- The symptoms you describe, particularly the presence of blood and the increased mucus, are concerning but manageable.
Explanation:
Infections after sinus surgery like FESS can occur, especially if there’s been any compromise to the nasal or sinus tissue. The green mucus and foul smell typically indicate a bacterial infection, and it's good that you're already on antibiotics. Corticosteroids can indeed suppress immune function, making it harder for your body to fight off infections. Blood in the mucus can occur after surgery as well, especially if there is irritation. However, this should be monitored.
Next Steps:
-
Follow Antibiotic Regimen: Take the prescribed antibiotics exactly as directed. Completing the full course, even if symptoms improve, is essential to fully eradicate the infection.
-
Hydration: Increase your fluid intake to help thin mucus and prevent dehydration. Aim for 6-8 glasses of water daily, or more if you feel dehydrated.
-
Rest: Your body is healing. Ensure you’re getting adequate sleep and rest to boost your immune response.
-
Monitor Symptoms: Keep an eye on symptoms. If you notice worsening headaches, a significant increase in blood, or if you develop fever and chills, these could be signs of a more serious issue and would require immediate evaluation.
-
Nasal Care: Since you’ve recently stopped corticosteroids, consider using saline nasal sprays to keep your nasal passages moist. This can help ease irritation and promote healing.
Regarding your concerns about severe complications, while infections in the sinus regions can have serious implications, prompt treatment typically prevents more severe consequences, such as those involving the brain. If you feel your symptoms are worsening or you remain concerned, don’t hesitate to reach out to your healthcare provider for reassurance and further evaluation.
Stay positive; recovery can take time, and you are taking the right steps by addressing your concerns and following through on your treatment plan.

Persistent Swollen Lymph Nodes for Five Months
Personal Background: I’m a 19-year-old transgender male, standing at 175 cm (approximately 5’9”) and weighing around 125 lbs. I am of Caucasian descent and have been sober from alcohol for eight months and from marijuana for seven months, with no use of other recreational drugs. My current medications include 25 mg of sertraline daily (I began taking sertraline when I was about 13 or 14 years old; my dosage peaked at 150 mg but has remained at 25 mg for nearly two years), a weekly subcutaneous injection of 50 mg testosterone enanthate (started 3.5 months ago), 20 mg of lisdexamfetamine (initiated 1.5 months ago), and I take daily contraceptive tablets containing 0.15 mg levonorgestrel and 0.03 mg ethinyl estradiol (I’ve been on birth control since I was 14, which I started about six months after my menstrual cycles began due to intense pain and excessive bleeding; I switched to the current BC pill at age 17). Additionally, I was diagnosed with high cholesterol two months ago, with my cholesterol profile being: total cholesterol at 200 mg/dL, triglycerides at 101 mg/dL, HDL at 52 mg/dL, LDL at 130 mg/dL, non-HDL at 148 mg/dL, and LPA at 83 nmol/L (my LDL previously peaked at 171 in December 2023). I also have diagnoses of autism and ADHD. I experienced precocious puberty starting at age five due to a benign cyst in my pineal gland. My family history includes cancer, with one parent having had colorectal cancer and the other cervical cancer, both of whom are now cancer-free. Main Concern: I have noticed two swollen lymph nodes in my neck, located just below my ear, behind and slightly above the angle of my jaw. The left node has been enlarged for a minimum of five months, while the right one has been swollen for at least four months. Both nodes feel firm and do not move when I apply pressure. The left node initially grew to the size of a medium pea before stabilizing as I began noticing the right node. For months, both lymph nodes were approximately the size of a smaller than dime but have recently increased in size over the last two to three weeks. The dimensions from the top (underneath my ear) to the bottom of both are roughly equivalent to the length from my fingertip to the first knuckle on my index finger. Their shapes have become more oval, with the left node presenting a smaller bump atop the larger one. Both nodes are now slightly visible from the front and become more prominent when I tilt my head. I first identified these nodes after accidentally bumping them and have since tried to avoid excessive touching to prevent worsening their condition. What could this indicate? I currently do not have a primary care provider but see an endocrinologist at my university for testosterone and cholesterol management. I have an upcoming appointment with my endocrinologist in two weeks. Should I wait until then to discuss my concerns, or would it be advisable to secure an earlier appointment with another physician?
Discomfort from Swollen Lymph Nodes in the Groin Region (24F)
I’m currently trying to schedule a visit with my physician; however, the discomfort I’m experiencing is becoming quite bothersome. Periodically, particularly enough for it to raise concern, I notice lump-like swellings appearing in the crease of my groin, at the junction where my thigh meets my pelvis. These bumps cause mild pain, and while they are somewhat firm to the touch, they also possess a degree of mobility. Applying pressure results in pain, and there have been instances where it feels as though something bursts inside, occasionally leading to a small rupture on the surface releasing a white discharge. Despite their appearance, I suspect these are not acne but rather swollen lymph nodes. I maintain good hygiene, showering regularly and cleansing that area thoroughly, so I doubt this is due to inadequate cleanliness. The swellings seem to resolve themselves within one to two days, measuring anywhere from a centimeter up to an inch in size, but they tend to recur frequently. This cycle of discomfort is unsettling, and I am uncertain about the underlying cause. Any suggestions or insights regarding this matter would be immensely appreciated.

Understanding the Risks of the Facial 'Danger Triangle'
I’m 32 years old, 170 cm tall, and weigh 65 kg. My current medications include Visanne for endometriosis, escitalopram, apprilon, and Allegra. Recently, I stumbled upon information regarding the "danger triangle" on the face, which highlights how infections in that region can result in severe complications such as cerebral venous thrombosis (CVT), stroke, or meningitis. This knowledge came thanks to a trending topic on social media. Now, I'm feeling quite anxious about it because I’ve noticed some pimples forming in that specific area. I generally avoid popping them, but the other night, one of them ruptured beneath a pimple patch. This particular spot was just to the left of my nose. After cleansing thoroughly while showering, I've experienced persistent discomfort under that area. I can’t determine whether the pain stems from the superficial skin or from the sinus cavity behind it; it’s been rather bothersome, especially since my skin has always been sensitive. The pimple in question was quite small and seems to have healed relatively quickly. However, I’m left with a burning sensation where it was located, and I'm unsure if this discomfort is related to the surface of my skin or deeper, possibly involving my sinuses. Notably, I haven't experienced any other symptoms. I’ve had acne in this area before, but it never caused me concern until I learned about this unsettling danger triangle. Any insights or advice would be greatly appreciated!
Understanding Suprascapular Nerve Entrapment
**Age**: 30 **Gender**: Male **Height**: 6 feet **Weight**: 170 pounds **Ethnicity**: African American **Duration of Symptoms**: 5 months **Affected Area**: Left shoulder blade (scapula) **Medical History**: No significant health issues reported **Current Medications**: None prescribed Greetings, I’ve noticed noticeable muscle wasting both above and below the scapula spine on my left side. This condition affects the supraspinatus and infraspinatus muscles. I’m experiencing reduced strength in shoulder movements, particularly in external rotation, abduction, and a minor reduction in flexion. I suspect that this may be due to nerve compression at the suprascapular nerve caused by a traction injury that has persisted for over five months now. I am curious whether a full recovery can still be achieved through an arthroscopic nerve release surgery, or if the extended duration of the nerve entrapment diminishes the chances of a complete recovery.
