I woke up this morning feeling VERY tired. after about 1/2 hr I realized that I'm constantly stretching (like a cat does when they lay down & stretch o the point of almost being a crescent moon). I also was extremely cold but since the weather has just started getting cold here I thought I just wasn't used to it. I turned my heater on but it did nothing to take off the chills. then I realized that when I get a fever I constantly stretch to where it almost hurts. I took some aleve in addition to my other meds (morphine, protonix, lisinopril,). I'm also taking estroven, mucinex (I have a congested ear) & 2.5 mg of percocet. my thermometer isn't reliable so I always take it in both ears but no fever. it's now been about 2 1/2 hrs since I've taken those meds (I took 4 over the counter ones, I think 600 mgs each) & my fever is now at 102. I need to know when I should consider going to the ER. in 2012 I had pneumonia twice so I'm VERY concerned about having that again! I also went to the ER 4 times that year because my body was having some kind of reactions to my pain meds.
