There's more intel about Miley Cyrus' hospitalization and condition.

Her reps explained that the singer is a victim of a really bad sinus infection and a severe allergic reaction to medication prescribed to treat that issue.

Cyrus, who canceled a second Bangerz Tour date, shared a hospital bed selfie, looking like she doesn't feel that great, too.

Cyrus' team told TMZ that she got a prescription for cephalexin, an antibioitic, to treat a sinus infection. She was diagnosed in North Carolina and canceled a show in the state due to being under the weather.

Within days of taking the meds, her throat became so swollen that the singer could hardy speak. That lead to her hospitalization on Tuesday night (April 15), where her doctors diagnosed her with an extreme reaction to the drug. She had never taken the medication before, so she had no ideas she was allergic and this is how she found out. It could take almost a month before she fully recovers from this allergic reaction. Yikes.

The doctors are keeping her under their care until she improves.

There were rumors she was worn down due to her grief over the death of her pooch, Floyd, during the tour.

Meanwhile, the singer shared a bed selfie in the hospital with her fans, captioning it as such: "over the hospital I miss #bangerztour #5amhospyselfie so sleeeeepy #medztime #wishicouldcuddlefloyd #whojinxedme." Notice she mentioned her poor pup Floyd, which is weight on her mind.

Feel better, Miley!
