Mine didn't go away either, honestly, so you're not alone there. I asked my gynae about it during my postnatal checkup at KKH and she said some just stick around, especially if there's a family history. A friend of mine saw a dermatologist at a private clinic for hers and got laser treatment done, and she said it made a real difference, but it took a few sessions. If it's really bothering you, I'd say start with asking your PD or gynae for a referral to a good dermatologist rather than guessing which doctor to see, since they'll know who handles vascular stuff well in your area.
Yes mum, mine stayed after pregnancy and I had quite a few visible veins with aching around my legs. A friend recommended a vascular clinic in Singapore where Dr Sujit Singh Gill consults. He found that I also had small varicose veins and performed sclerotherapy, and my legs looked much better afterwards. 😊❤️🩹
