Sudden itchiness all over skin?

Anyone know what this could have been? On Saturday night, I had sudden itchiness all over, but mostly legs, arms. Then, i had welts that looked like bug bites, and they went away, (i assume hives) Today, just my feet and palms are itchy. I had the flu and was on Tamiflu, but it didn't happen until 3 days into the medication. Could I be allergic?

Also, would I see a dermotologist for this?

Thanks!

Re: Sudden itchiness all over skin?

Sounds like a reaction to me.
Are you taking anything with an antihistamine? (like nightitme cold/fly medicine?) I'm wondering if that medicine suppressed it or would help.

You can go to your PCP for that or you can go to a derm but it sounds like a reaction to me
