I have been perscribed oxycodone for pain management before and after surgery and tolerated it well for many, many months. But lately Ive been getting a little sick and cold, clammy type sensations. Any advice, I take these for legit pain and can't stop so I need advice on why I suddenly am having problems and how to combat those problems. Anybody else experience this, or is it just me. I dont understand why I am suddenly feeling sick after tolerating it so well for so long. Could it be that im not eating right?Thanks for any input.
