cephalexin

hi all,

i had a lumpectomy on my right breast about two and a half months ago, i recently got quite bad internal pains and an ultrasound found an infection (retroareolar abscess). i'm half way through my prescribed dose of cephalexin, which has hit me hard, like dizziness, weakness, tiredness, stomach pains, basically every side effect it could have is happening. i'm wondering if anyones had a similar experience with cephalexin and how they managed it?

thanks!!
