My grandson was released from the hospital Friday morning. He is a CF patient and while in the hospital has surgery on his nose to remove a cyst. He became very sick - itching, stomach ache, and swollen lip with the meds they gave him to fight the infection from the surgery. Last night (Friday) his knees hurt so badly that he felt that he could not walk, the back of his arms ached, and his back itched with bumps that looked like bug bites. His lip is still slightly swollen. What could be causing this? He was sent home on Cipro. could this be the cause?
