Dry Skin on Baby’s Head

So ima. First time mom and I’m definitely feeling a little stuck at the moment. My daughter is 10 months almost 11. I noticed she had like a dry patch of skin on the back of her head. And then the day after I found that, while bathing her I felt a little bump on her head next to the patch. Took her to the pediatrician, and she said her lymphnodes were swollen and that she had yeast on her head. I was prescribed clotrimazole, and it seemed to make it worse. It became a bump and developed pustules. She’s now bald in the places I put the cream. Took her back and was now prescribed nystatin. And now it seems to just be the same. This bump is just growing slowly and I don’t have a dermatologist appointment until November 5th. I’m just feeling really lost and don’t know what direction to take. I can’t stand looking at this everyday. It’s been about 2 weeks now. I could use some advice or encouragement or anything really. Thanks so much in advance.
