Tingling feeling

Chloe🇬🇧

My little girl is 5 weeks old and I have been breastfeeding since the start and pumping since week 2 , the past 2/3 days my breast have had a tingling feeling between feeds when filling back up , they are rock soiled within 2 1/2 hours of feeding and pumping ! Is this normal ? My little girl only wakes once during the night usually after sleeping for 4/5 hours so when she does wake up for a feed they are so full and uncomfortable has anyone got any tips to help with this ?
