When you are an enlightened Buddha do you have no more worries or fears and desires?

All Buddhist traditions hold that a Buddha is fully awakened and has completely purified his mind of the three poisons of desire, aversion and ignorance. A Buddha is no longer bound by Samsara, and has ended the suffering which unawakened people experience in life. The term buddha is also used in Theravada to refer to all who attain Nirvana. Within the Buddhist tradition, this term has commonly been interpreted as the extinction of the "three fires",or "three poisons",passion, (raga), aversion (dvesha) and ignorance. But does this all mean that fe Siddartha Gautama never worried about his health or was never doubting about hisself whether he was doing good or not?
