Lindsay Lohan returns to Twitter after health scare

LONDON, Jan. 22 (UPI) -- Lindsay Lohan returned to Twitter Wednesday just hours after she was released from a hospital in London.

The Mean Girls star, 28, was hospitalized at King Edward VII's Hospital after being diagnosed with a high fever and "unbearable" joint pain, according to TMZ. Both symptoms appear to be linked to the rare virus Lohan contracted while on vacation in French Polynesia in December.

Lohan did not address her hospitalization or her symptoms on her tweet and instead called attention to CSV Positive Futures, the youth-volunteer nonprofit she's been working with in London.

The actress spoke about contracting chikungunya, a virus that spreads though mosquitos bites, before the New Year and said she "[refused] to let a virus effect my peaceful vacation."

According to TMZ, upon returning to London from her vacation, Lohan was unable to walk because of her symptoms.

Insiders told E! News "the doctors told her it could take six months to a year for the virus to clear up. She has good days and bad. Right now, she's not doing so well."
