Hi. 1st time here. Lately I have been very tired. So it all started last week when I was tested positive for strep. I was really sick running fever. I was in a after hours clinic and after I was told it was strep I did get dizzy and they had me l as y down gave me water and a cold press. I seemed fine after that. Then about a day after taking the antibiotic cefdinir I noticed I was feeling tired but I also went to bed between hrs. Of midnight and 1 am and waking around 5 am. Then since being off a week for Thanksgiving I have been going to bed late and sometimes waking up during night. I am trying to sleep more but also still going to sleep late at night but I always have been a night owl. But now I am worried something more serious could be wrong. Am I being crazy thinking something is wrong... I get short lil headaches but nothing long term I am wondering if it is from the tiredness or me just continuing to stress about this.
