9 month sleep regression?

My daughter is nine months and two weeks old. At the beginning of the month she had a horrible ear infection and although she was previously sleep trained sleeping 11 to 12 hours a night no problem she started waking up from the ear pain screaming for 3 to 4 hours a night no matter what we did. Whether we laid her down or held her. So we went to the doctor and he put her on amoxicillin. Within a few days of amoxicillin she had horrible diarrhea and then developed a bad bad red raised rash. She had some nights where she'd sleep okay and other nights where I'd be up with her at least three hours getting her to just settle enough to stay asleep. But sometimes the problem for sleep didn't happen until the middle of the night but she would be okay at the beginning of the night. In the last week she's ended the amoxicillin and one night out of four she actually slept 10 hours without waking me up but the other nights I've been up with her for at least three hours because previously to this sickness she would settle herself if she were to wake up and now she stands in her crib crying. The amoxicillin is done her diarrhea is starting to go away and so is the rash. Last night she stood up in her crib after sleeping for four hours and just screamed and my baby is not a huge screamer but she just cried until I walked in and then as soon as I picked her up she wanted to play with me, play with my ears play with my eyes, giggle. play. She did not have a poopy diaper like previous times when I've gone in and I can tell that was the reason that she had woke. I tried cuddling with her but she didn't really want to fall asleep so I'd laid her crib and she would cry I would go back in that in five minute intervals but she just cried and cried. The last time I went in I made sure that she was dry, I made sure I had given her just a couple ounces of milk which I don't really ever do but I wanted to see if maybe she was hungry for some reason. I gave her some Tylenol in case her ears were hurting her again. I laid her in her crib and tried to pat her back and she kept trying to stand up. Finally after three hours was up she let me lay her down and she was able to put her self to sleep. But I did realize that just yesterday she started pulling up a lot on furniture and standing and she also climbed up the first step. I know that I've read about nine month sleep regression. I know that I've read about milestones and wonder weeks. And I just feel like I'm at my wits end. I'm not sure what to do for her when she wakes up. Before I sleep trained her, she would wake up in the middle of the night and Id go in and I pick her up and she would fall asleep in my arms within a few minutes and I could lay her back down. But now she is crying and sometimes even when I pick her up she doesn't want to be comforted I even put her down on the ground cause she kept looking at it from the chair to see if maybe she wanted to crawl and she sat there and cried. So I'm just wondering if at nine months anybody else's children had some major issues. I thought that when she was done with her medicine and done being sick she'd start sleeping again. She still does okay for her naps for the most part she puts herself to sleep and sleeps for an hour to two hours each time. Twice a day. I also was wondering if maybe an earlier bedtime would help. She's always been a late night baby. She usually sleeps 10 to 10. If anybody has any advice or insight or just let me know that I'm not the only mom out there with a confusing baby. It would really help me. The baby monitor is starting to give me anxiety. Thanks so much for anybody's insight or help. Sorry for the lack of paragraphs, i used my iPhone for this post.
