Is It Normal for Mosquito Bites to Follow Veins?
Age 26, weighing 300 pounds. No current medications, diagnosed with Ehlers-Danlos Syndrome (EDS) in 2017. I've noticed a recurring phenomenon every time I venture outdoors and end up with mosquito bites. While not every bite triggers this response, a significant number do. After being bitten, it seems that the reaction often travels horizontally from the original bite location, which I suspect is tracing along a vein. Typically, this movement extends about an inch from the bite site before it fades away, paralleling the lifespan of the bite itself, which lasts a couple of days. There are instances when I experience quite large welts that become swollen; however, I've encountered these less frequently recently. In contrast, the trace effect following the veins appears to be happening more consistently. I’ll provide an image of a recent event in the comments where I was outside for just ten minutes and received several bites.

It sounds like you're experiencing an unusual reaction to mosquito bites, particularly the way the irritation seems to move along your veins. This can be concerning, especially with your history of Ehlers-Danlos Syndrome (EDS), which can affect skin sensitivity and response to allergic reactions.
Explanation:
When you're bitten by a mosquito, your body releases histamines, which can cause localized swelling, redness, and itching. If the reaction appears to spread, it may be due to the way your body is processing the allergens, particularly in someone with EDS who may have more sensitive skin and a different response to inflammation.
The movement of the irritation along the vein may not necessarily indicate a severe issue, but it can be indicative of heightened sensitivity or an abnormal immune response. Large welts are typically a common allergic reaction, but the accompanying movement of irritation is interesting and could be related to your EDS, which affects connective tissue and possibly your immune system’s response.
Next Steps:
-
Monitor Your Symptoms: Keep track of how often these reactions occur and note any changes in size, color, or duration of welts. This can help identify patterns or triggers.
-
Minimize Mosquito Exposure: Use insect repellent with DEET or another effective ingredient, wear long sleeves and pants, especially in the evening when mosquitoes are most active, and eliminate standing water around your home.
-
Manage Reactions: Consider using over-the-counter antihistamines (like diphenhydramine or cetirizine) at the onset of bites to help reduce swelling and itching. Apply topical corticosteroids to the sites of bites to help with inflammation.
-
Consult if Necessary: If you notice any significant changes in your reactions (like difficulty breathing or prolonged swelling), or if the reactions become more severe, consider consulting an allergist or dermatologist for further evaluation.
-
Educate Yourself on EDS: Understanding more about how EDS affects your body can help you manage symptoms better. Look into resources or support groups for individuals with EDS.
Please remember to take care of your well-being and prioritize avoiding situations where bites occur. Let me know if you have further questions or if you want more information about managing your symptoms!

Excessive Electrical Shocks Encountered
Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
Urinalysis Inquiry
Subject: Urinalysis Results Review Age: 23 Height: 5'2" Weight: 101 lbs Greetings! I would appreciate it if you could review my urinalysis findings. The test was conducted yesterday, just one day prior to the start of my menstrual cycle, and I am now currently on my period. Below are the details of my results, as I need this information to fulfill a prerequisite for my employment. Additionally, I would like to know whether my menstrual cycle may have influenced the outcome of the test. I typically experience frequent urination, yet I do not have any discomfort or pain while urinating.
Combining Ketorolac with Alcohol: Is It Safe?
Recently, I unknowingly mixed a 10mg dose of ketorolac with half a bottle of 4.5% beer. At that moment, I wasn't aware of the potential risks involved in this combination. It wasn't until I was partway through my drink that I thought to look it up. Now, I’m wondering if it’ll be fine for me to have a drink tomorrow night after stopping all ketorolac use, especially since this medication hasn’t been effective for my pain relief. To give you an idea of the timeline, I took ketorolac around 2 PM and didn’t start drinking until 11 PM.
Concerns About My Eye Condition
I'm a 19-year-old female, weighing 190 pounds and standing 5'5". Lately, I’ve noticed some troubling changes in my eyes. There are prominent, red veins extending from the inner corners of my eyes into the irises. Additionally, there are bright red streaks and pools forming at the lower part of both eyes beneath the eyelids, bordered by a yellowish hue. When I consulted two different doctors, they were unable to pinpoint the issue and simply recommended lubricating eye drops. Unfortunately, the condition seems to be deteriorating, with the redness spreading further. While there is no significant pain, keeping my eyes open feels like a struggle, and my vision has become increasingly blurry, leading to some headaches. I’ve been unwell recently, but I’m uncertain if this has any relevance to my eye problems. Any advice or insights would be immensely helpful.
Experiencing Numbness in the Right Arm or Leg?
Hello! I’m a 17-year-old assigned female at birth, weighing approximately 110 pounds and standing around 5 feet 2-3 inches tall. At the moment, I’m not taking any medications and I don’t smoke. Recently, I’ve been facing a peculiar issue where my right leg or arm occasionally becomes numb. This sensation only impacts my right side and never the left. It can occur at any time, both during day and night. Typically, the numbness in my leg arises when I’m lying in bed, although I also experience it randomly throughout the day. I’m curious if anyone has any insights or thoughts about whether this could be something more serious than just a problem with my posture, haha!
