Hello. My husband, who is 53, a construction worker has been diagnosed with celluitits of head just behind his right ear spreading down his neck. He was diagnosed by a doctor on call, over the phone. He was prescribed 40mg of pepcid, 10 mg of Zertec, cephallexin 500mg 4xday, prednisone 20mg. He has taken two days worth of medication. Tonight I noticed that he has an all over body rash. Small pimples widely spread out on his body, red around, some scabbed over. They appear to be random, but consistant. Not bunched together. Sparse over his forearms and lower legs, more over his torso, and chest, and back. He was also prescribed pain medication, which has helped his pain significantly. I did not notice the rash before, but from the looks of it, it has been there, when his symptoms started around 5 days ago. Should we consult the doctor with this new observation?
