Multiple throat and skin symptoms related or unrelated?

Hi!
Ive been having quite a few symptoms for the past couple of months that just aren't adding up. During the winter I had what seemed like strep throat (swollen neck glands, white pus on tonsils,). I was diagnosed with "sinusitis" and given nose spray and antibiotics. My tonsils are still a little large and its been 5 months, but they are not painful at all. I also get occasional dry mouth. I have also been suffering from hives caused by any friction on my skin for about a year now. I usually take allergy medicine and it prevents it, but allergy med. doesnt work as well anymore. Most recently, I have these 3 brown, flakey, small patches on my stomach. They are not itchy, but seem to go away and then come back. I was prescribed a steroid cream, and told it was nothing to worry about, but that did nothing. Other little symptoms pop up but seem irrelevant. I was just wondering what the heck is going on in my body! is it just crazy allergies? Your help is appreciated
