She's no stranger to hospitals, but Dr. Jen Arnold found herself on the receiving end of health care this week.

The "Little Couple" star is beginning to battle a rare form of cancer and shared a selfie of her bald head in the hospital on Friday (December 27).

Keeping positive, the neonatologist tweeted, "Day2 inpatient chemo- sleeping alot, liking new anti nausea med this time, & looking to get home today! #GetWellJen."

Though earlier in the week her treatments had to be postponed due to low blood counts, Jen noted, "Silver lining was a better Xmas."
