Well, must not be poison ivy.   Yay!!

Get up in the morning, pain is gone, still a tingling sensation at the
attack points, but that's it!

So, anyone know what this is??

Thanks again!!

Could be nettles.  They have minute spikes which pierce the skin and
introduce an irritating material, which stings for a while.  Annoying
but harmless and source of many wise folk sayings, e.g. "grasp the
nettle firmly".  Hives (urticaria), an allergic reaction of the skin,
was once called "nettle rash", although not caused by nettles.

That said, reaction to poison ivy is variable.  Some people get
horrible symptoms, some get annoying symptoms, and some, like me, get a
trivial immediate mild reaction that lasts for a few hours.

Since you don't say where you are, it's harder to speculate on what
other plants you might have run into.  You may also have an
idiosyncratic allergic response to something that few people react to.
