I Got My Prescription For Oxycodone 15mg Filled On Tuesday

I got my prescription for oxycodone 15mg filled on Tuesday I have a pill count and blood work to be done one week after I got my script filled that's this Tuesday I get 90 pills a month I have been taking them but I'm 10 short I think it's because I took more than 3 a day for a few days My regular Doctor sent me to a neurosurgeon and he gave me a cortisone shot in my back about a month ago and my back is ten times worse, what I need to know is will they take my pills when the count doesn't come out right
