skin or soft tissue infection
"Had a ingrown toenail infection. Was given 500mg keflex taken 4 times a day for 7 days.

It is working and I have no pain in my toe. However... so far I've had diarrhea, stomach pain, extreme tiredness and weakness, dizzy spells, yellow skin, loss of appetite, nauseous, red scratchy eyes. So most of the usual stuff. The long and short of it is my toe will be healed as long as I can deal with the side effects for a few more days."
