possible side affects

Is it possible while on ANY type of morphine related drug, you have cold seats constantly? I'v tried opana...kadian... have been on and off of percocet and each time i thought is was the specific drug so tried staying off everything except percocet, Had two separates disk graft/fusions with over;appong titanium plates which encompasses 5 of 7 cervical disks. Am in constant pain but at this point the cold sweats are about to make me commit suicide....and thats no morphism...I'm serious. At my wits end. Goe to many different drs whom all have a diffferent answer...different meds but getting worse... not better...HELP
