Looking for similar stories or advice... I got stung by wasps yesterday (belly just above my hip, little finger, and upper arm) and it was very painful but as the day went by, the swelling/pain/redness diminished. Called 111 to be safe, but advice was fairly vague except to not taking any anti-histamine unless prescribed. They also said to monitor it, that it shouldn't really get more than a 50-pence coin in size for swelling.
However since this morning, the zone on my belly is inflammed again (I thought it could have been just from rubbing on the bedsheets but it's persisting) with some (little) swelling, and the whole area is about 10cmx3cm... Any ideas?
