Significant Drop in BP, Heart Rate, and Oxygen Levels Post-Blood Draw
I'm a 22-year-old female, 5'2" tall, weighing 98 pounds, and I am currently on a 20mg dose of Lexapro. I have a quick question about my experience after having blood drawn this morning, although I doubt my details are crucial. Following the procedure, I noticed a drastic decline in my blood pressure, which I believe fell to 60/40 based on past readings. My oxygen saturation was as low as 80, and my heart rate dropped to 30 beats per minute. I appeared very pale and found it necessary to rest for quite a while afterward. Is this a common reaction? This seems to occur routinely for me.

It sounds like you experienced a significant drop in blood pressure, heart rate, and oxygen levels after your blood draw, which is concerning and not typical for most individuals. Here’s a breakdown of what you may be experiencing and some immediate next steps.
Key Points:
- Blood Pressure and Heart Rate Changes: A blood pressure reading of 60/40 mmHg and a heart rate of 30 beats per minute are well below the normal ranges and can indicate a serious issue.
- Symptoms: Feeling pale, weak, and needing to rest are responses your body may have when under stress, such as from blood loss or anxiety.
Explanation:
Your reaction could be due to several factors, including:
- Vasovagal Response: This is a common response to blood draws, where the body’s nervous system reacts. It can result in a sudden drop in heart rate and blood pressure, sometimes leading to fainting.
- Hypotension: If you are prone to low blood pressure or are underweight, you may be more susceptible to these reactions.
- Potential Dehydration: If you didn't hydrate properly before the blood draw, it might have contributed to these symptoms.
Next Steps:
-
Monitor Your Symptoms: Keep track of how you feel after similar procedures in the future. Note any recurring symptoms like those you just experienced.
-
Stay Hydrated: Drink plenty of fluids before and after any blood draw to help maintain blood volume and pressure.
-
Eat Something Light: Ensuring you have eaten something, especially before a procedure, can help stabilize your blood sugar and overall energy levels.
-
Rest and Recover: Listen to your body — take the time you need to recover after having blood drawn, especially if you have these kinds of reactions.
-
Consult with a Healthcare Provider: Given that these reactions seem to happen routinely for you, it’s important to discuss this history with a healthcare provider. They might suggest further evaluation or management strategies.
Please keep a close eye on your symptoms, and do not hesitate to seek immediate help if you experience severe changes or feel unwell again. Your health is important, and addressing these concerns professionally will help ensure your safety.

Electrocution or Anxiety: What Just Happened?
Duration: 15 minutes. I experienced something bizarre when someone struck my hand with a spring, sending it flying. The pain was intense, and I could swear I felt my hair stand on end, similar to when you get goosebumps. That red mark on my hand triggers the same reaction in me. Have I experienced electrocution, or could this be a reaction stemming from anxiety?
Experiencing Bluish Lips Post-Exercise
Greetings! I’m a 23-year-old female who has been exercising regularly—combining gym workouts, Pilates, yoga, and cardio—about three to four times weekly for the past two years. Recently, however, I’ve encountered a peculiar issue: after my heart rate decreases following cardio sessions, my lips turn a bluish hue. This discoloration persists for roughly 30 to 45 minutes before returning to normal. Additionally, I have a history of unusual allergic reactions linked to exercise, exposure to sunlight, and hot showers, which often result in hives and itching. To manage this, I take Zyrtec daily. I have an appointment with my doctor this Saturday for another matter, and I plan to mention this issue to them. In the meantime, I would appreciate any insights or experiences you may have related to this condition. Thank you!
Noticeable Veins on Forehead
At 25 years old, weighing 115 pounds and standing 5 feet 4 inches tall, I've noticed a concerning change this morning. The veins in my temples appear significantly more pronounced, particularly on the left side, compared to the right. Although they aren't swollen, their color is much darker than I typically observe. I'm feeling a bit anxious about what this could indicate and would appreciate any insights or guidance!
Red Bumps Observed on Right Foot
I'm a 27-year-old male who discovered some red bumps on the surface of my right foot about four to five days ago. While I initially did not experience any itching, I ended up scratching the area which resulted in some discomfort. I applied hydrocortisone ointment right away, which alleviated the itching. Aside from my right heel, I haven't noticed similar bumps elsewhere on my body. My partner and I first considered the possibility of bedbugs; we conducted a thorough inspection of our bedding but found no evidence. Since then, I’ve also washed all affected items. Notably, my partner has not shown any signs of having bumps. I’m monitoring the situation closely; thankfully, the bumps haven't spread or caused any additional symptoms. I’m just trying to figure out what may have caused this issue.
Traveling with Lung Conditions: Seeking Advice
Hello everyone, I hope I'm in the right forum to discuss this important concern. A bit about me: I’m a 30-year-old male who doesn’t smoke cigarettes but does consume cannabis. Alongside my lung complications, I deal with a range of persistent pain problems, including migraines, ADHD, and significant anxiety. I’m currently on medication for these issues: clonazepam manages my anxiety, Vyvanse helps with ADHD, and I occasionally take over-the-counter pain relievers since my doctor is quite restrictive with prescriptions. For migraines, I use Imitrex. I was born with a condition known as pulmonary blebs and have endured three spontaneous pneumothoraxes. I've undergone one thoracic surgical procedure, specifically a blebectomy, to address the blebs on my left lung. Unfortunately, I experienced a mild lung collapse on that side around five years after the surgery, which took place in 2020. The right side, however, has not yet been treated because it's currently considered non-urgent by my medical team. The crux of my inquiry revolves around travel. I've always dreamt of exploring new places, but I’ve been advised that my lung condition might pose risks, especially with changes in air pressure during flights. For instance, I’ve been cautioned against scuba diving for the same reason. I’m wondering if there are any specialists who could clarify whether flying would likely increase the risk of a lung rupture, if it's a remote possibility, or if it truly is a gamble with uncertain odds. This issue has prevented me from traveling my entire life, and I’m eager to find out if I can venture outside of Canada. If flying is deemed feasible, would it be wise to limit myself to shorter flights, or should I avoid air travel altogether to mitigate any potential risks of a mid-flight complication? Thanks for any insights you can share!
