Short itch span
I feel a bite and then itch for a few minutes in bed then the itch leaves. What’s biting me ? Thanks for reading this. John Sakal, Toronto Ontario.

It is impossible to know whether you are being bitten or not from your description, let alone know what could be the possible cause for that sensation.
You need to investigate it yourself, and report back if you find any potential culprits. It is probably something else if the sensations stops.
