Aah I understand lah, first time IV drip memang scary! My friend pun was nervous gila when she had to do blood transfusion sebab HB rendah after delivery, tapi the nurses were really supportive and it went smoothly. Vitamin C drip and blood transfusions are common procedures, so try not to worry too much, just make sure you eat well with iron-rich foods after, and follow-up with your doctor to see what caused the HB to drop so it doesn't happen again. Kalau ada specific concerns about the procedure itself, best check with your doctor or the nursing staff who will explain exactly what they're doing, they deal with this every day, okay?
