first of all inorder to know if the levels are high i need to know is it in mg, mls etc... as all labs use different reagents to test,
if your husband developed lip swelling
and rest of the symptoms after taking the medications it seems he has developed an allergic reaction
to one of the medication he has been given i suggest stop taking the medications
visit the hospital to be given medication to prevent further reaction to go on.
hope have answered your query
get well soon.
