I have been taking pain meds for back pain. Oxycodone was prescribed for the pain which causes me to become nauseated. I take Zofran for the nausea. I have been taking both for about 2 weeks. Now I am feeling nof breath, headachy, heaviness in my chess. I also do not have an appetite. I have not been able to sleep through the night without waking up 4-5 times. Is there something short of going to the emergency room that will give me some relief? I have not taken any pain meds since Sunday morning.
