sore nipple after 4 months pain free breastfeeding- help

[Hallloumi]

Hi,
I'm dbf and it was going great. Lats week I had what I think was a blocked duct so fed more from that side. It seems to be settling and no sign of mastitis but that nipple is now incredibly sore. no cracks just red and sore. Despite ibuprofen I can;t stand to feed from that side and I've never mastered expressing so am concerned (especially that the blocked duct will get worse). I can buy nipple shields tomorrow- is that a good idea, I could also buy an electric pump as so fgar have only tried hand expressing and manual pump (and have never got more than an ounce). Baby won;t take a bottle either......
advice appreciated

Oh poor you. I know how you feel. Have you been using any cream on your nipples? Does it appear 'chapped'?

I successfully got rid of blocked ducts through massaging boob in shower. Work towards nipple from behind blocked area. You have to go quite firmly (it fecking hurts!) - using your knuckles, or a wide-toothed comb if you can stand it. If boob is very engorged then a hot flannel compress before massage can help.

Not sure about the sore nipple. Could you have a blocked duct at the nipple?

Thanks for your replies. After posting I got a tender white bleb on my nipple which I lanced using a sterile needle and continued the heat, massage etc. It's now all better so must have been a blocked duct ? in 2 places.
