Severe Reaction to Yellow Jacket Sting Hours Later
A 21-year-old male, standing at 5 feet 10 inches tall, experienced a yellow jacket sting just shy of his ankle, near the Achilles tendon. Now, over four hours later, he finds it nearly unbearable to remove the ice pack from the site for even a minute, due to intense pain. He reports no additional symptoms and has been managing the pain with Tylenol and Benadryl, applied his sting relief treatment twice since the incident. What could be causing this extreme reaction?

Experiencing intense pain hours after a yellow jacket sting can be distressing, and your symptoms suggest a potentially significant local reaction. Here’s a structured overview of what might be happening and steps you can take.
Main Points:
- Severe local reaction to a yellow jacket sting is concerning but can occur due to a variety of reasons.
- Continued symptoms may indicate a strong inflammatory response or even possible allergic reactions, despite no additional symptoms being present.
Explanation:
Yellow jacket stings can induce varying degrees of reactions. While some people experience mild discomfort, others may have more severe pain and swelling at the sting site, which can persist for hours or even days. This intense pain could be due to:
- Increased inflammation: Your body may be reacting strongly to the venom, leading to localized swelling, redness, and pain.
- Allergic reaction: Even in cases without additional symptoms, some individuals may have an allergic response to insect venom that manifests as pain and swelling at the sting site.
- Necrotizing fasciitis or infection: Although less likely without other symptoms, any break in the skin can introduce infection, potentially leading to more severe reactions.
Next Steps:
-
Continue Cold Therapy: Keep applying ice packs to the sting site for 15-20 minutes every hour as tolerated. This can help reduce pain and swelling.
-
Elevate the Area: If possible, keep the affected leg elevated to minimize swelling.
-
Pain Management: Continue using Tylenol (acetaminophen) as directed for pain relief. Monitor the effectiveness and adjust if needed.
-
Watch for Symptoms: Keep an eye out for any changes. Seek immediate medical attention if you notice:
- Increasing red streaks spreading from the sting site.
- Severe swelling beyond the immediate area of the sting.
- Fever, chills, or worsening pain.
- Difficulty breathing or swallowing, or dizziness.
-
Mild Compression: Gently wrapping the area (not too tight) with an elastic bandage can help but ensure it’s not cutting off circulation.
If your symptoms don’t improve or worsen over the next 24 hours, or if you have concerns about your condition, consider seeking medical evaluation for further assessment. Remember to keep track of any new symptoms, as this can be helpful for healthcare professionals if you need to seek further care.

Seeking Insights on Ongoing Symptoms
Hello everyone, I’m a 23-year-old female, and I recently underwent a colonoscopy last Thursday, but it has left me with even more uncertainty regarding my health. For the past three months, I have been grappling with several troubling symptoms. These include stools that are often pencil-thin—sometimes accompanied by bright red blood—severe constipation that can last for days, followed by bouts of diarrhea. I've also been experiencing a significant loss of appetite that resulted in a weight drop of 15 pounds since early May. Exhaustion haunts me, as I often find myself taking 4-6 hour naps on my days off yet still feeling drained afterwards. Other concerns include shortness of breath, painful backaches, daily nausea, a frequent urge to use the bathroom, hair thinning, bloating, and extreme belching. Due to my family’s history with colon cancer, fear consumed me; I was convinced that I had a few months left to live. This anxiety prompted me to quickly secure an appointment with a gastroenterologist recommended by the emergency room after I sought help for severe pain and constipation on May 5th. They performed a CT scan, which came back normal, and an ultrasound indicated the presence of multiple small ovarian cysts. A doctor at the ER identified one of these as having ruptured on the same day, but the symptoms continued, albeit with a milder sense of abdominal discomfort that just won't go away. After my colonoscopy, the only findings were one internal and one external hemorrhoid, which sounds like good news because it rules out cancer. However, the doctor didn’t provide much clarification during our brief conversation. He suggested I might have lactose intolerance, advised seeing a gynecologist, and sent me on my way. While it’s a relief that there’s no cancer involved, I’m left puzzled about how this addresses the unusual symptoms I’m experiencing. Why have I been observing consistently pencil-thin stools for three months? I monitor my stools each time I manage to go. Hemorrhoids don’t seem to account for this condition, at least not in the long run, do they? Could potential lactose intolerance be a contributing factor? If everything is somehow linked to gynecological issues, could that also cause my stool shape? I'm in a state of confusion! Thank you for taking the time to read my post!
Concern About Mild Cellulitis on Inner Thigh: Should I Be Worried?
At 30 years old, I've found myself facing what seems to be a mild case of cellulitis on the inner part of my thigh, and I can't help but feel unsettled about it. On Thursday evening, I noticed an unusual, dark purple pimple forming on the upper inner thigh. Unsurprisingly, I tried to pop it, but it was quite painful, and nothing came out. By Friday night, I observed that a red area, measuring around 1x2 inches, had developed around the blemish. Fast forward to Saturday afternoon, and the redness had intensified, expanding to about 2x3 inches. I sought medical attention at an urgent care clinic where a nurse practitioner drained the area and prescribed both oral and topical antibiotics, which I have been using diligently throughout the day. As of late Saturday, I'm uncertain if the size is still increasing, but the inflamed area appears to be morphing into a larger 3x3 blob; perhaps this is due to pulling off the bandage. My concern escalated when I browsed through Reddit and stumbled upon various accounts detailing severe cases of cellulitis. Horror stories filled the thread – tales of near-death experiences, unbearable pain, and even amputations. There seems to be a lack of reassurance, with most sharing tales of ineffective oral antibiotics that resulted in prolonged hospital stays on IVs rather than any comforting reports suggesting it would be okay. I am left wondering when I should seriously consider heading to the emergency room, especially since my symptoms seem limited to a light red oval surrounding the abscess. While I have dealt with skin infections before, this one is unusually alarming given its rapid growth. It's causing me quite a bit of anxiety, and it's interfering with my sleep.
Abdominal Discomfort and Concerns
Male, 29 years old, currently only taking 10mg of Ezetimibe for cholesterol management. As I approach the third week of experiencing discomfort in my abdomen, I've noticed a persistent sensation of pressure and bloating concentrated at the lower part of my torso. This feeling tends to change based on whether I am sitting or lying down. To articulate the experience, it resembles a bubble of air pushing upward beneath my ribs and extending into my lower back, as though air has detached from my internal organs and become lodged in my lower abdomen. I’ve sought medical attention at both an urgent care facility and from a specialist. My evaluations included a urine analysis, blood work, a breath test, and a CT scan both with and without contrast; however, these tests have yielded no clear findings. There are no obstructions, diverticulitis, infections, or swelling evident. The only notable result was a slight elevation in calcium levels from my blood tests, along with minor indications of fatty liver. I am currently waiting for an appointment with a gastroenterologist to schedule a colonoscopy, but I can’t shake the anxiety that this could indicate something more severe. Passing gas requires a small amount of effort, and defecation takes moderate effort. Nonetheless, it feels as if I am not fully evacuating my bowels. My stool is neither hard nor dark, nor is there any blood present. The only instance of loose stools occurred when I took a laxative under the impression that I was experiencing a blockage. My family medical history includes only my mother, who had uterine cancer. Are there any insights or advice?
Seeking Insight on Persistent Leg and Foot Issues
Hello Reddit community, I’m a 20-year-old female, standing at 5 feet 6 inches and weighing 130 pounds. For approximately five years, I have been experiencing numbness in my legs and feet. During my freshman year in high school, I participated in cross country and track without facing any problems. However, during my sophomore year, around 25 minutes into a run, I began noticing a peculiar numbness that starts at the lower part of my foot and spreads upwards along the back of my leg. Initially, this sensation would only occur late in my runs and would subside shortly after stopping. Over time, the onset of these symptoms has worsened, appearing sooner and lingering longer after activity. I've also dealt with noticeable weakness in my calf, ankle, and knee, which heightened my fear of potential falls while running cross country. After several sessions of physical therapy, I was sent to a cardiologist who suspected I might be suffering from popliteal artery entrapment syndrome (PAES). Following an ultrasound and angiogram conducted by local physicians, no issues were detected, leading to a referral for compartment testing to a specialist an hour away. This physician, after taking in my history and conducting several ultrasounds, expressed confidence in proceeding with a left leg medial approach for popliteal artery release, questioning the validity of prior tests. Regrettably, my recovery from surgery did not yield any improvement; my symptoms intensified and began to occur even when standing, not just during running as previously experienced. In pursuit of further answers, I approached the Mayo Clinic, where an extensive series of tests was conducted, but ultimately, I was left without a clear diagnosis. Now, I'm facing three treatment paths: a complete compartment release across all four areas to confirm or rule out the condition (which sounds overly invasive and risky), a more aggressive posterior popliteal entrapment procedure (though I wonder if previous surgery would have resolved PAES if it were the issue), or the option to receive Botox injections targeting both chronic exertional compartment syndrome (CECS) and PAES (this solution entails multiple injections for potentially temporary relief and may face insurance challenges). As a young, engaged nursing student, this situation is remarkably challenging. I struggle to stand for any substantial period without discomfort, leaving me feeling quite limited. I've encountered numerous physicians with differing opinions, making me feel somewhat lost in this situation. I would greatly appreciate any guidance or insight from those who might understand what I’m going through. At present, my symptoms include: - Numbness in my feet (distinct from the pins and needles sensation) after standing for around 30 minutes, walking briskly, or even running, which I rarely do now. - Pain behind my knees after standing for over half an hour, accompanied by discomfort and weakness in that area. - Weakness in my ankles, making it difficult to lift my foot while attempting to step forward. - General pain, weakness, and discomfort while standing or walking, with recovery taking several days. The following tests have been performed: - EMG (four instances, with one specifically to rule out tarsal tunnel syndrome) - MRI (five instances) - Lower Extremity Ultrasounds (six instances with popliteal entrapment maneuvers) - Compartment Testing (twice) - ECG/TEE - Blood Tests for Connective Tissue Disease - Evaluations for Dysautonomia, Autoimmunity/Paraneoplasia - Catecholamine Endocrine Study - Autonomic Reflex Screening - X-rays of the tibia and fibula - Angiograms (twice) - Exercise VO2 Max test - Overnight Oximetry monitor - Previous PAES release surgery Results from the Compartment Tests showed: Pre-exercise / Post-exercise readings: - Right Anterior: 14/27 - Right Lateral: 19/26 - Right Deep Posterior: 12/20 - Right Superficial Posterior: 12/21 - Left Anterior: 8/19 - Left Lateral: 20/29 - Left Deep Posterior: 12/14 - Left Superficial Posterior: 11/17 Thank you in advance for any support or insights you may be able to provide!
Changes in Vision: My Experience and Concerns
I'm a 22-year-old female weighing 210 pounds and residing in the U.S., and I have a mixed eye prescription. My journey with strabismus began with surgery at the age of two, followed by another procedure at fourteen. Unfortunately, the eye that was treated has started to become lazy again a few years post-surgery. Lately, it seems that my vision has deteriorated further, leading me to my latest prescription. I'm seeking clarity on what this indicates about my condition and what I might anticipate moving forward. Could it mean my eyesight will continue to decline?
