I had my 6th child 9 days ago, I had a cannula put in side on my wrist y giving birth ready for hormone drip but as it went in bled badly and was very uncomfortable, I asked for it to be taken out after drip finished but took a few hours, my hand was swollen n was sore, today it's swollen up again very sore with a rash all over my wrist and big lump where I think the cannula ended. Hand looks very veiny and fills like it wants to burst, should I be worried. Many thanks
