Black Spots on Tongue and Rash

Hi all,   For years I was diagnosed as having ulcerative colitis but was just recently diagnosed with Crohn's in September of this year. My GI doctor after a colonoscopy found ulcers on my small intestine which lead to me being diagnosed with Crohn's   I have been going through an awful flare up but I am starting to feel better. During the worst part of my flare my GI doctor prescribed me two antibiotics, Cipro and Metronidazole and I went off of those about three weeks ago. I'm also now tapering off of Prednisone. I went from 60mg and am now currently down to 20mg.   about two days ago I developed a rash on my forearm, neck and legs but didn't think anything of it because it's happened to me before I even started the antibiotics and Lilada. The rash doesn't hurt, itch or is rasied. It just kind of pops up here and there and then disappears. Also, this morning my wife noticed that I developed small black spots on my tongue.   Is this common with having Crohn's disease? I have read that rashes were but I can't find anything about black spots on tongues.

Antibiotics and pepto can give you those black spots on your tongue. I would try brushing it a couple times and see if that helps.

Antibiotcs can also cause thrush, which would then make your tongue white and feel kinda hairy (yeast infection).

A dermatologist??? Shouldn't he suggest an ENT?
What do the spots look like? Could they be tiny blood clots?

I wonder if he even paid attention or heard when you said you had black spots on your tongue.
You can always go to a walk-in or call your family doc.
