Unexpected Appearance of Petechiae on My Right Arm?
Greetings, I’m a 28-year-old male, non-smoker, who drinks occasionally. Today, I discovered several petechiae on my right arm. It’s a condition I'm unfamiliar with. I haven’t experienced any trauma to this limb; there has been no scratching or itching involved. Currently, I’m not on any medications. Although I do suffer from seasonal allergies which have recently flared up, I have never encountered anything of this nature before. I consulted my family physician who performed a thorough examination to check for additional spots elsewhere on my body but found none. He inquired about any fever or pain I might be experiencing, which I do not have. His advice was to keep an eye on this condition, and he instructed me to reach out should it worsen or if I notice any new symptoms. A month ago, I underwent a complete blood count after visiting the ER for persistent stomach discomfort; this dull ache occurs in my upper abdomen but is not severe. The results from that CBC were within normal limits, except for a slightly low RDW. I’m left puzzled about the origins of this issue—should I be concerned? I will post further details in the comments.

The appearance of petechiae—small, pinpoint red or purple spots on the skin—can be concerning, but it’s important to understand that they can arise from various causes, some benign and others more serious. Given your current situation and health history, it's good to monitor this, but here’s a structured breakdown.
Main Points:
- Possible Causes: Petechiae can result from factors like minor trauma, allergies, infections, or even specific blood disorders. Since you've recently experienced increased seasonal allergies, this could be connected.
- Current Evaluation: Your physician's examination showed no other spots, and you don't have fever or pain, which is reassuring.
- Monitoring is Key: Keeping track of any changes is essential, especially since you have a history of stomach discomfort.
Explanation:
Petechiae are often small and may not indicate a significant problem; however, they may point to an underlying issue, particularly if they appear unexpectedly or in clusters. Low platelet counts or certain allergic reactions might cause these spots, but since your complete blood count was mostly normal, it’s a hopeful sign.
Next Steps:
- Keep Monitoring: Watch for any changes in the petechiae, such as an increase in number, changes in appearance, or the development of new symptoms (like fever, fatigue, or bruising).
- Symptom Diary: Maintain a record of any new symptoms or changes in your health, especially related to your allergies or stomach discomfort. Note any correlation with activities or exposures.
- Hydrate and Rest: Ensure you're hydrated and resting well, particularly if you're dealing with seasonal allergies. This can help your body manage any allergic reactions more effectively.
- Stay Alert for Symptoms: If you notice any new, concerning symptoms, or if the petechiae change or increase significantly within the next week, consider reaching out to your physician again for further evaluation.
Your physician's advice to watch and wait is sound, given the context, but staying informed and aware will empower you to react promptly should the situation change. Let me know if you need further clarification or support!

Confronting an Unidentified Sexual Disorder
Experiencing an Unidentified Sexual Disorder At 17, I find myself grappling with Post Orgasmic Illness Syndrome (POIS) since my teenage years began. This condition has been quietly eroding my well-being, progressively worsening as time goes on. The initial signs emerged when I was approximately 13 or 14 years old. Following masturbation, I began experiencing a nagging brain fog accompanied by heightened anxiety. At that stage, the symptoms were manageable, far less intense than what I endure today. Back then, my experience was largely filled with discomfort due to my habit of masturbating every other day, with symptoms lingering for around two days. For a prolonged period, I was puzzled about the source of my distress until I gradually recognized a pattern. One fateful Friday when I was about 15, I made the regrettable choice to masturbate in the afternoon before meeting friends. The aftermath was disheartening—overwhelming brain fog and a surge of anxiety made socializing nearly impossible. I struggled to maintain conversations or even meet my friends’ eyes; it was so out of character that they questioned what was happening with me. It was then that I acknowledged the connection to masturbation. I began strategizing; I would only engage in that activity when no social commitments loomed. This approach somewhat helped me regain control over my social interactions. However, as the years rolled on, my condition deteriorated significantly, requiring me to recover for five days instead of just two. I was exhausted and had reached my limit. My life was unraveling because of this situation, resulting in lost friendships and a diminished bond with my family as the illness transformed me into someone unrecognizable. In a bid to break free from triggers, I deleted all social media platforms like TikTok and Instagram and refrained from masturbation for an entire year. As a teenager, that was an extraordinary commitment. During that time, I felt rejuvenated, formed numerous new friendships, and achieved my best academic performance. Ultimately, I graduated. I was genuinely content. But, of course, happiness was fleeting. I met a girl from my class who captivated me. We conversed and eventually dated; she seemed like the girl of my dreams—flawless in every aspect. Knowing deep down that this would likely end poorly for me, I still yearned to savor these moments of joy from my youth. After a handful of dates, we became intimate. Following the experience, I was terrified she would reject me upon witnessing this altered version of myself. Unfortunately, the symptoms returned, even after a year of abstaining. Nevertheless, she embraced me for who I am, and we have been in a relationship for almost a year now. Yet, POIS continues to wreak havoc in my life. While I attempt to maintain a five-day gap between our sexual encounters, I still face overwhelming symptoms. I struggle to think clearly, formulate coherent sentences, sustain eye contact, and deal with anxiety that arises for no apparent reason. My facial expression often mirrors that of a drug user, and the sparkle in my eyes has vanished. I have experimented with numerous supplements, yet none provide even close to the relief I seek. A visit to a neurologist yielded little result, since she was unfamiliar with POIS and proposed a referral to an allergy specialist who also lacked knowledge, turning me away. Next, I consulted a urologist who prescribed prednisone and silodosin. While prednisone proved somewhat effective, its long-term effects are far from appealing. Silodosin offered no significant benefits. Interestingly, silodosin only worked at a dosage of 10mg, requiring consistent intake before and after activity. Moreover, I experience severe symptoms even in close proximity to my girlfriend—someone I adore. This reality is profoundly unfair; even gentle gestures such as kissing or hugging send my brain into turmoil as it associates these actions with sexual repercussions. I am devoid of hope for my future; no semblance of a normal life seems attainable unless I adopt a monastic lifestyle, disconnected from women. The mere thought of that possibility spirals me into deep depression. I plead for just one doctor or specialist to take this condition seriously. The people suffering like me need recognition for how devastating this illness can be. It’s bewildering; I was once an ordinary kid. Now, I’m just a shell of my former self, constantly observing and wondering about the person I could have become without this disorder. Even on symptom-free days, I remain crippled by fear of their return. I feel perpetually unstable and fragile. Just because most individuals can engage in sexual activity without issues doesn't mean those of us with conditions like this are exaggerating. I wouldn't wish this suffering on my worst enemy.
Sudden Swelling in One Foot: Possible Causes?
I’m a 31-year-old male, and recently I experienced a shocking swelling in my foot that grew significantly within six hours, as depicted in my image.

This isn't the first time it's happened; I dealt with a similar swelling a year or two ago, but I hadn't faced this problem again until just recently.
Could My Dad Catch Mono From Me?
Recently, I (28-year-old female) received a positive diagnosis for mononucleosis. Just yesterday, while sipping on a can of sparkling water, I left it in the fridge to enjoy later.

Could These Signs Indicate Seizures? Let's Explore the Possibilities
A 22-year-old female, standing at 5’8” and never having smoked, seeks insight into some concerning symptoms. She has a background of obsessive-compulsive disorder (OCD) and depression, along with inflammatory arthritis. There’s also a suspicion of narcolepsy, pending a sleep study for confirmation. Recently, she discovered that the symptoms she’s been experiencing might resemble seizures, pending validation by a neurologist. There's a familial history of epilepsy, though no one in her family has experienced a full seizure event. She hadn’t considered this potential connection until her doctor raised it after discussing her symptoms, which began during her seventh-grade year. - She describes a peculiar sensation in her brain akin to rapid vibrations or shaking. - Alongside this, her vision appears to shake, making it difficult to see properly—she experiences intermittent blurriness. - Each episode typically lasts around ten seconds, with only a few occurring each year. However, in the last three months, she has had approximately four episodes. - Importantly, she notes that during these instances, she remains fully aware and retains memories of them. Do these symptoms suggest a specific type of seizure? If yes, what kind could they be?
Tonsil Troubles: Seeking Advice
Age: 24 Gender: Male Height: 6’2" Weight: 200 lbs Ethnicity: Caucasian Duration of symptoms: Approximately one month Location: California Preexisting health conditions: None Current medications: Clindamycin Greetings, everyone. I've been experiencing some serious issues with my tonsils lately, and I’d like to share my journey. Initially, I tested positive for strep throat and was prescribed a ten-day course of penicillin. By the end of the treatment, I felt much better. However, just two days later, I relapsed with a fever and all my prior symptoms returned. This prompted a five-day course of Zithromax (Z-Pak). Shortly after completing the Z-Pak, I noticed a slight soreness in my throat, leading me to begin taking clindamycin. Thankfully, the sore throat subsided the following day, and now, six days into this treatment, I'm testing negative for strep. Despite the negative test, I'm still noticing some troubling signs — namely, white patches on my tonsils, bad breath, and an unusual taste in my mouth. I don't feel any significant pain, though I occasionally sense a mild ache in my ear when I concentrate on it. At this point, I'm feeling quite uncertain about what steps to take next. I worry that once I finish this course of antibiotics, the illness will return, and I am eager to resolve this situation for good.
