Oh yes, that pins-and-needles feeling on the scalp is actually more common postpartum than people realise, some mums describe it exactly like that, tiny ants crawling on the head, and it can be linked to nerve sensitivity or tension that builds up after delivery, sometimes even connected to how the body is still adjusting hormonally. A friend of mine went through something similar and found that a mix of approaches helped, things like physiotherapy, acupuncture, and just being more intentional about posture and rest, though what worked for one person didn't always work for another. If it comes with light sensitivity, vision changes, or the sensation is very persistent, that's really worth flagging to your doctor sooner rather than later, just to rule out anything that needs closer attention.
