18mo DD pulled a pan lid out of the cupboard this morning and it fell on her big toe :( She now has what looks like a large blood blister forming under the nail. The toe is clearly sore but she is walking around and seems fairly unbothered. She doesn't mind me touching the toe.
Does this need medical attention? Not dealt with blood blisters before so have no idea if there is anything a GP would do or whether it will clear up on its own.
Thanks :)
