My face, head, chest and back are full of what look like hives. I have a few on my legs. A few of them look like very bad pimples. I saw my Doctor on Friday and he drew blood and I am taking Doxycycline Hyclate. I am fatigued and my appetite is not good at all but I do not have any of the following, itchy, headaches, sore neck or nausea. I never had chicken Pox but I do not have those symptoms. Any Doctors with any ideas?

It would be foolish and dangerous to attempt to diagnose you on the Internet.

You saw a Doctor. I'd believe him/her.

As Judy noted it is dangerous to diagnose on the internet. So please understand that is not my intent. However, Doxycycline Hyclate (see Contraindications) can cause redness and capillary blockage, a condition known as Erythema which bears some similarity to what you describe. Some photos of this condition can be viewed here for your comparison.

"Erythema multiforme on the leg". This picture is the closest to any of the other pictures but a little different from what I have. From what I described could it be a tick? What else could have caused this problem from what I described. I appreciate your help.

I'm trained in physiology and look to exogenous elements such as drug reactions. When it gets beyond that it's up to MD's trained in pathology to determine cause and treatment. So you're probably better to wait for the blood workup. Just thought it could have possibly been a reaction to the DH. Wish I could be more help but I am not experienced or qualified in the area of your complaint.
