Understanding the Unusual Patches Beneath My Knees
I’m a 31-year-old woman with a medical history primarily involving mental health conditions such as ADHD, OCD, anxiety disorder, and depression. Fortunately, I don’t have any physical ailments. Currently, I’m on a treatment regimen that includes Effexor and Wellbutrin. However, I’ve noticed some unusual patches under my knees that resemble bruises. These marks have persisted for several years without fading and do not cause me any discomfort. Despite this, people often comment on how it looks like my knees are bruised, which affects my confidence in wearing shorts or skirts. What could these patches signify?

The patches you’re noticing under your knees that resemble bruises but are painless and have persisted for several years could be related to a few different factors. While they may appear concerning, if they don't cause discomfort or change over time, they usually aren't a sign of a serious health issue. It's encouraging that you don’t have any underlying physical ailments.
Possible Explanations:
-
Dermatological Factors: These patches could be caused by skin conditions such as:
- Dermatitis: Inflammation of the skin that can cause discoloration.
- Eczema or Psoriasis: Can sometimes manifest as unusual patches.
- Hyperpigmentation: Areas of the skin might become darker due to various causes, including sun exposure or post-inflammatory changes.
-
Vascular Issues: Sometimes, changes in blood vessels can lead to bruising-like appearance without actual bruising occurring.
-
Medications: Certain medications can have skin-related side effects but might not be specifically linked to Effexor or Wellbutrin.
Next Steps:
-
Observe Changes: Keep an eye on the patches over the next few weeks. Note if they change in color, size, or if any new patches develop. This information can be helpful.
-
Sun Protection: If the patches are exposed to the sun, using sunscreen can help prevent any further darkening or irritation.
-
Skin Care Routine: Consider using a gentle moisturizer to keep the area hydrated, which may help with the appearance of the skin.
-
Confidence in Clothing Choices: Remember that many people have skin variations and it’s normal. If you feel comfortable, aim to wear the clothing you love regardless of what others think. Your health and well-being are what truly matter.
If there are any significant changes to the patches, or if you have other symptoms in the future (like itching, discomfort, or new skin changes), consider tracking these and looking for guidance on dermatological management. Please remember, it’s always a good idea to address any concerns with a healthcare professional who can provide personalized advice.

A Unique Shade of Perspiration
For as long as I can recall, I have experienced a peculiar phenomenon—my sweat is blue. This unusual trait has resulted in my t-shirts developing noticeable blue stains in the underarm area. Despite this oddity, I maintain a robust level of health at the age of 30. Thankfully, it doesn’t lead to any other complications, aside from the simple need to frequently purchase blue shirts.
Cortisol Deficiency
At 27 years old, standing 5 feet 5 inches tall and weighing 90 kilograms, I've recently received alarming news from my physician regarding my health. My doctor informed me that my cortisol levels are significantly below normal, registering at just 24 nmol/L. Despite this concerning diagnosis, I have not experienced any negative symptoms and have felt perfectly well throughout the past week. My doctor suggested that I might need to go to the emergency room; however, I feel my overall well-being does not warrant such drastic measures at this time.
Concerns About My Rabies Vaccination Experience
At 19 years old, I found myself in a troubling situation after encountering a bat in my bedroom. Consequently, I sought immediate medical attention at my local emergency room, where I was provided with the full course of rabies treatment, comprising four doses along with HRIG PEP. I adhered strictly to the schedule for the vaccinations, but now I am left questioning whether the administration was executed correctly. On the first day, I received the HRIG injection in my left thigh, paired with the initial dose in my left arm. However, when I returned on day three for my second vaccination, I again had it administered in the same arm. Caught up in my nervousness and perhaps a lack of good judgement, I asked the staff to give me the subsequent doses on days seven and fourteen in my thigh instead. I thought this would be wiser, as I read that deeper muscle injections yield better efficacy, and I felt that my upper arms were too thin compared to my more muscular legs. The nurses complied with my request and injected me in my left thigh for both doses. Subsequently, while doing some research on websites from the CDC and WHO to reassure myself, I came across alarming information. I learned that: 1. It's generally advised against injecting adults in the thigh for these types of vaccines. 2. Injecting the vaccine into the same muscle as the HRIG is not recommended. With these concerns mounting, I returned to the hospital seeking boosters, but my request was dismissed by the staff, who insisted that everything was administered correctly. This has left me in a state of anxiety ever since. While I want to trust the judgment of healthcare professionals, my experience raised doubts, especially since they initially mentioned the option of administering the injection in my buttocks—another area reportedly not advisable for this treatment. Living in a rural town where this hospital is my only option for care amplifies my unease. Were they accurate in their assessments, or should I be preparing for the worst?
