i didnt have any rashes but my coll has very serious rashes. the more she scratch, the worse it gets. cant sleep 'cause vvv itchy. n it spreads when you scratch it.
for me, though i didnt kena those rashes, i kena it months after delivery. doc said it's eczema, due to hormonal change n that my boy might get it after 6 month old. but luckily he didnt.
doc ask me to avoid all seafood (esp prawn, lobster, crab) and ALL CITRUS stuff (e.g. orange, tomato,...) i suspect mayb 'cause i eat too much of orange and tomato during pregnancy. mayb overdose. that's y body cannot take it. anyway, no medical evidence on that .
mayb you want to try avoid all seafood n citrus stuff n c how. also, keep the rashes moisturised. if you can keep it covered, that would b good. also try not to scratch.
as for lying on left side for blood circulation n baby, i read about it too. but sometimes dont feel comfy sleeping that way. so i dont really care. as long as i can sleep comfortably, can already. dont force yourself to sleep in certain position. if you can sleep on left, then sleep. if not, just change to right. but whenever you can, try to sleep on left 1st. not comfy then change position. put more pillows to support your back n betw your knees. will b more comfy.
