Fainted After Blood Test: A Scary Experience
At 28 years old, standing 6'1" and weighing 263 pounds, I have always been in good health. Today, I finally went for my annual medical examination after a three-year hiatus. When the nurse measured my blood pressure at the start, it showed 130/78, but shortly after, I began to feel dizzy. They then directed me to the lab for my blood tests. As the technician was withdrawing blood, I started to feel extremely nauseous, breathless, and dizzy. I recall her instructing me to lean back and paused the blood draw, but everything went black — I fainted. When I regained consciousness, I found myself surrounded by a doctor and several nurses. They quickly took my blood pressure again, which was alarmingly low at 68/29. The medical staff speculated that my fainting might have been due to having skipped breakfast that morning and my general anxiety about needles. While I usually bypass breakfast, I've had blood drawn on an empty stomach before without any issues, and I’ve never encountered something like this previously. I’m left questioning how serious this episode was. As I understand it, a blood pressure of 68/29 is dangerously low, and I'm uncertain about what steps to take next.

I'm sorry to hear about your fainting episode; that can certainly be a frightening experience. It's positive that you had immediate medical attention, and while a blood pressure reading of 68/29 is indeed low, there are steps you can take to ensure your health moving forward.
Key Points:
- Fainting (syncope) during blood draws can be related to anxiety, dehydration, or low blood sugar.
- Your low blood pressure indicates a temporary state that can sometimes occur after fainting.
- It's crucial to address any lifestyle factors that may contribute to fainting episodes in the future.
Explanation:
Fainting can happen for various reasons, and in your case, it may be a mix of having not eaten that morning and possibly feeling anxious about the blood draw. When blood volume decreases (from factors like not eating or dehydration), blood pressure can drop significantly, leading to symptoms like dizziness and fainting.
Next Steps:
-
Stay Hydrated: Ensure you're drinking plenty of fluids, especially water, before medical appointments or blood draws. Aim for at least 8 glasses a day, more if you're active.
-
Eat Regular Meals: Try to have a balanced meal before you have any procedures that could make you anxious. Eating something small like a piece of fruit or yogurt can help maintain your blood sugar levels.
-
Manage Anxiety: If needles cause significant anxiety, consider practicing relaxation techniques such as deep breathing or talking to a supportive friend or family member beforehand. Next time, inform the healthcare staff about your anxiety; they can provide extra support.
-
Monitor Symptoms: Keep a record of how you feel before and after blood draws or other similar situations. If you notice patterns or repeated fainting, that information will be valuable.
-
Follow-Up Monitoring: Make sure to keep an eye on your overall health, including regular check-ups. If you experience further fainting episodes, persistent dizziness, or changes in your blood pressure, consider discussing these with a healthcare professional for further evaluation.
Take care of yourself, and don’t hesitate to reach out if you have more questions or need further clarification. Your health is important!

Concerns about Unusual Marks on My Penis (29M)
I’m a 29-year-old male and I've recently spotted two unusual marks on my penis. This has been troubling me for about a week now, and I can't shake the feeling that it could signify something serious. My hygiene isn’t the best since I don’t shower frequently, and I’m hoping it might just be a mild fungal infection that I can manage before it escalates. I’d appreciate insights from anyone knowledgeable in this area. A bit about my health background: my latest blood test, conducted around eight months ago, indicated I was significantly deficient in vitamin D, so I’ve been taking 4000 IU supplements daily and plan to have another blood test soon. Additionally, I deal with mild anemia and have been diagnosed with juvenile rheumatoid arthritis, seronegative type. I also regularly take methadone and clonazepam. Unfortunately, I’m not a person who showers often—there are weeks when I might go without bathing, largely due to feelings of severe depression and stress that have greatly diminished my motivation. I'm also underweight at 58 kg and typically struggle to consume even one full meal a day. Importantly, I do not believe this is related to a sexually transmitted infection, as I have not been sexually active. Would it be advisable for me to see my family doctor or seek out a specialist? Financial limitations make this a challenging decision for me right now. Thank you for any guidance you can provide.
Concerns About My Cardiologist Only Communicating with My Dad
This past year has been exceptionally challenging for my health (I’m 22), with a history of severe dysmenorrhea that evolved into critically low iron levels requiring frequent infusions. Then, the headaches started—debilitating migraines accompanied by auras such as tinnitus, nausea, and spinning sensations, persisting for days without any noticeable link to my menstrual cycle. Despite my gynecologist’s advice to discontinue my combined birth control, the migraines persisted. I then switched to a progesterone-only contraceptive but had to end that due to life circumstances. After several months without a period and after consulting a new gynecologist who investigated thoroughly, I was diagnosed with PCOS and multiple large fibroids. Currently, I'm on a new medication (Slynd) and awaiting a suitable time for surgery. Additionally, I experienced unexpected weight fluctuations, gaining 40 pounds rapidly and then losing 10 within a week, along with various digestive issues. I now believe these may be symptoms related to my other conditions, even though my specialists (and it’s a baffling thought at my age, having multiple specialists) all deem this normal. The most alarming issue, however, has been my episodes of tachycardia, where my heart rate would spike to around 115-120 bpm for extended periods. After some hesitation, I used my roommate's pulse oximeter for verification. Following a visit to the emergency room, where they found nothing egregious (just a slightly oversized heart and some atherosclerosis), the doctors attributed my symptoms to anxiety. But I am certain it’s not anxiety. After returning home for the summer (preparing for my final year at college), I decided to check my blood pressure using my father's cuff. The readings were concerning: 145/70, followed by 155/68 during subsequent checks. With a family history of hypertension—my father having high blood pressure since he was 18—he urged me to consult his cardiologist. Unfortunately, during the appointment, the cardiologist largely ignored me and directed his comments towards my dad, advising me to lose weight despite my balanced diet and regular workouts. Moreover, the cardiologist dismissed my symptoms as resulting from anemia without communicating that to me directly, conveying all information only to my father. Initially, I chalked it up to a misunderstanding because they called early one morning while I was still asleep. However, during my iron infusions, my nurse expressed concern about my blood pressure being significantly elevated (like 160/85). This high pressure persisted at every infusion session, regardless of treatment effects. Out of concern, my father contacted the cardiologist’s office to schedule an appointment ahead of my return to college. Supposedly (and given my father’s forgetfulness, I can't be sure), they decided to prescribe me amlodipine without ever consulting me personally. There was no direct communication regarding my symptoms, no explanation of the medication, nor assessment of possible interactions with my birth control—of which there are significant risks pertaining to hyperkalemia and stroke. I'm picking up the medication today and plan to consult with the pharmacist about potential interactions. Yet, I can’t shake this feeling of unease regarding the cardiologist’s office. I don’t mind sharing information with my dad—communication is vital—but I firmly believe I should be directly involved in discussions about my health. Now, I'm left questioning whether this situation is typical and how I might navigate it while still keeping my father as one of my emergency contacts. His involvement is important to me, but I also need to advocate for my own healthcare communication.
What’s Going on with My Feet?
Lately, I've been observing some unusual changes with my feet. It seems that any sort of pressure applied, even just resting my feet on my bed, causes a yellowish discoloration. After a while, a burning sensation follows—imagine the feeling of electrical sparks zipping through the soles and then somehow merging into my bloodstream. It’s difficult to articulate, but it’s as if the pain feels static in nature. Additionally, I've noticed my toenails tend to appear rather pale; perhaps that's normal, but I’ve never really focused on that before. Historically, my feet have had episodes of turning purple, so that aspect isn’t entirely foreign to me. However, this change now occurs even while I'm lying down, whereas in the past it would usually only happen after standing for extended periods. I have been diagnosed with POTS, which I suspect is the reason behind my purple feet, yet the emergence of these yellow patches is a recent development. Not only do they look unattractive, but they can also be quite painful. I would truly appreciate any insights into what might be triggering these symptoms. Thank you so much! 💕 Also, I apologize for the dust on my feet! My dogs had just returned from their walk and decided to lounge on my bed. I only noticed the mess after snapping the photo; please overlook that! 💗
Unexpected General Anaesthesia: A Patient's Experience in Australia
I’m reaching out for some guidance regarding a medical situation I faced in Australia. Hello everyone, I recently underwent a procedure for an ingrown toenail, and prior to surgery, my surgeon had clearly stated that it would be performed using local anaesthesia. However, the documentation provided by the anaesthetist mentioned details about a general anaesthetic. Since my surgeon had assured me that only local anaesthesia would be utilized, I mistakenly regarded the mentions of general anaesthesia as standard information that was not applicable to my case. My discussions with the nurses during the surgery prep focused on the local method, particularly as I am currently breastfeeding. They expressed more concern regarding the use of general anaesthesia. When I entered the anaesthetic room, the anaesthetist didn’t explain his actions but informed me that he needed to insert a cannula into my arm. He then injected two syringes of what I later realized was anaesthetic before transporting me into the operating theatre. The next moment I was aware of, I was waking up in the recovery area, feeling quite startled. What should I do in this situation? Is it unreasonable for me to feel upset about this?
Inquiry Regarding Radiology Interpretation
Hello, I'm a 39-year-old male who recently underwent an MRI followed by a CT scan because of potential dehiscence, which seemed to align with my symptoms. The findings from the CT scan indicated that there is no evidence of dehiscence; however, it mentions that the SSCs traverse through the tegmen. While I possess a solid background in pathology, I'm at a loss regarding the implications of this statement, and my general practitioner was also unable to clarify it. The ENT specialist is currently on leave, and I am eager to understand what this means as I am quite perplexed. I've consulted a few colleagues with similar expertise, but they are equally puzzled. I appreciate any insights you can provide. Thank you!
