Hi i have just been in hospital with a ruptured cyst pain has eased but feeling very sick, shaky and have no energy is this a normal way to feel?

Could be: Feeling weak, shakey and generally fatigued certainly may be normal after a hospitalization. It is highly recommended to follow-up with your dr. Within the next 3-7 days post hospital stay, which you should do. Then a good exam, follow-up care that may include blood work can be accomplished to assure you are progressing and recovering normally. Best wishes.
