My 63yr. old father had hip replacement surgery and was in rehab when he developed a sore throat. The doctor prescibed Levaquin and within 8 hours he was incoherent and developed a severe allergic reaction. He had to be rushed to the hospital because his tongue was so swollen he had trouble breathing. It is 30 hours later and his tongue is still swollen but not as severe and they have a tracheotomy tray nearby just in case. He has muscle pain in both arms and it hurts him if you barely touch his arm. He indicated that on a scale of 1-10, the muscle pain is a 10.
