Thank you for your query at DoctorSpring.com
I understand your concern.
You have MRSA infection and that itself could cause hypothermia. You need to start taking the medicines as this infection can spread rapidly and till you take the medicines, it is not going to settle down.
Depression, fatigue, loss of weight and appetite are all the part of the infection.
If you take Clindamycin properly, you will feel a lot better.
Hope this was helpful,
Feel free to discuss further,
