My husband had flu like symptoms for about 3 days ( low grade fever, chills, aches, coughing, etc) The doctor said he had a sinus infection to which he perscribed an antibotic for (Bactrim). It took about 2 full days for it to kick in and he started feeling a bit better. On the 3rd day (this evening around 11:30pm) he started shaking and saying he was freezing (though his skin felt normal). I took his temperature and it was 95.3.
Does this have anything to do with the antibotic and his immune system already being low due to the flu? Maybe antibodies attacking the thyroid? Should this be something to worry about/should he stop taking this antibotic/or will it balance itself out?
Thank you!
