Itching came back a couple days later and keeps occurring on and
off every couple days. She event went through allergy
a full blood panel to look at thyroid etc. Now six months later family Dr says it is probably from that course of cephalexin she took 6 mos ago! He says it could last up to two years!!! How can this be possible. I can't believe any trace of that drug or its side effects could possibly stay with your body for two years!???? HELP!!!
