Swelling?

I'm not sure if it's a symptom of UC or an allergic reaction but on Friday night my face ballooned and really significantly in about 10-15 minutes
So I took Benadryl and the swelling went down
Also I got a lot of "steroid acne" and a lot of that disappeared
So I'm not sure if it's acne or hives cuz they look pretty similar
My face ballooned again tonight so I just took some Benadryl as I was putting on my pajamas I noticed that my legs are swollen
I'm not sure when that happened and it could be its new or was like that for days
has anyone else had facial swelling and swelling in their lefs?
Is this something to be concerned about?

I'm really scared to call the doctor because the last few times I called I was told to go to the hospital ( not only my current GI) and I'm very scared to go back as I rally really hate the hospital
I'm starting to get anxious about this
And now I remember that they asked me if I had swelling in my legs at my last appointment and they also checked them

You are going to have to bite the bullet on this one unless you want to wind up dead.
