Could I Have Accidentally Injected into an Artery?
I’m a 33-year-old trans woman, standing at 5'9" and weighing 180 pounds. For the past year, I have been administering subcutaneous estradiol injections in my abdominal area. This morning, I injected about three inches away from my belly button. Upon completing the injection and removing the needle, I noticed an unusual amount of blood. It appears that I may have struck a vein, but I’m really worried about the possibility of hitting an artery instead. I’d like to know if it’s dangerous to hit either a vein or an artery. I’ve been reading about the risks of oil embolisms online, which has left me quite anxious. Additionally, there was a small air bubble trapped at the top of my syringe prior to injection, and after I finished, it was still present. I’ve heard that injecting tiny air bubbles can be acceptable, but if I mistakenly injected a minuscule bubble into either a vein or an artery, should that cause me concern? Apologies for the lengthy explanation; it was alarming to see so much blood since I wasn’t expecting any at all, and I’m just hoping I didn’t make a mistake.

It's understandable to feel anxious after an experience like this, but let's break down your concerns and address them in a structured way.
Main Points
- Injecting near a vein is not uncommon, and it generally does not pose a serious risk.
- The presence of an air bubble in the syringe is typically not dangerous with proper technique.
- Monitoring for any unusual symptoms after the injection is important.
Explanation
When administering subcutaneous injections, it’s possible to accidentally hit a small vein. While it can lead to bleeding, it's usually not dangerous. Hitting an artery during a subcutaneous injection is less likely, but if it occurs, it can cause more significant bleeding.
Regarding air bubbles, research indicates that small bubbles (less than 0.5-1.0 mL) are generally safe to inject into the body, especially in subcutaneous injections. They often dissipate harmlessly in tissue; serious complications, like air embolisms, are quite rare in small quantities.
Next Steps
-
Monitor Your Injection Site: Keep an eye on the area for the next few hours. Look for signs like increased swelling, redness, or continued bleeding. If it continues to bleed, apply gentle pressure with a clean gauze or cloth.
-
Assess Symptoms: Be alert for any unusual overall symptoms like dizziness, light-headedness, difficulty breathing, or chest pain. If these occur, seek immediate attention.
-
Self-Care: After your injection, ensure the area is clean and avoid strenuous activities for the rest of the day to allow for healing.
-
Future Injections: For future injections, consider ensuring that you rotate sites and avoid areas with visible veins. If you're uncertain about your technique, you might look up instructional videos or guides.
If you have ongoing concerns or if the situation worsens, don't hesitate to reach out to a healthcare professional for personalized advice. Remember, it’s okay to reach out and clarify doubts whenever you feel uneasy about your health!

Potential Electrical Hazard from Using a Plugged-In Phone During a Storm
Last night, while I was asleep, a storm rolled through, and my phone was connected to the charger. After waking up, I began using it and felt discomfort in my hands and arms, but I chose to brush it off. The following day, I experienced an intense headache that has persisted and made me feel somewhat disoriented. I have since ceased using the phone, but I wonder how serious the risk truly was. Is there a possibility that I could have suffered a significant electric shock if lightning had struck a nearby power line?
Suspicion of a Fractured Nose
Subject: 30F Could anyone provide insight into whether my nose could be fractured? I've never particularly loved its appearance, but I have a concern that my son might have accidentally caused a break in my nose in 2023 due to his autism. Previously, my nose had a subtle hump, but now there’s an evident dip that wasn’t there before. I've also started to encounter serious breathing difficulties during the night that were absent prior. Consequently, I’m considering the option of rhinoplasty. I will share an image in the comments for better reference.

Verification of Medication Identification
Greetings to the group! I would appreciate your assistance with a matter concerning my medication. I have been prescribed doxepin or its generic form for approximately a year, and previously, the medication appeared as a green, oblong tablet. Recently, I collected my prescription (from the same doctor I've visited for the past five months), but found a different pill inside the container. The new pills are round and white, marked with the numbers 013 and an unusual letter 'P.' Despite my attempts, I was unable to locate any matches for these markings on various drug identification websites. Therefore, I would like to confirm whether these pills are indeed doxepin or its generic equivalent before I consume them. I appreciate your help with this!
Understanding Neutrophil Levels Before Starting Clozapine
Patient: 18-year-old female. Currently prescribed Haldol at a dosage of 5 mg, with plans to increase to 15 mg in the coming weeks. Additionally, there is a need to initiate treatment with Clozapine, beginning with a dose of 50 mg, eventually increasing to 100 mg. Recent blood tests show her neutrophil count is adequate at 2.86, though the percentage is at 43%, which falls below the desirable range. Lymphocyte levels are slightly elevated, possibly affecting the overall proportionality of white blood cells. Is it advisable to commence Clozapine treatment given these laboratory results? It’s worth noting that no significant alterations in the leukocyte composition were found.
