Question: I had a bad flu/cold about a week and a half ago. I had a fever of 99 to 100, a lot of congestion and one day of throwing up. (I think that was from something I ate.) I went back to work then had a bad cough and stayed home a day and a half. I slept a lot on Wednesday, and this Thursday when I went to work I had a lot of pain on left side under rib cage. I put heat on and it had a little impact and it is more localized pain. On Friday I became concerned, and called advise nurse, who sent me to ER due to pain being near chest. I had an x-ray, EKG, and urine sample, and everything was o.k. I continue to heat the pain, and maybe it was a little better during day yesterday, but I still feel pain under rib. Is this still from muscle soreness from coughing, and lying down, etc. (No fever for five days.) Is heat or cold better to relieve it? If it is not better within a few days, should I go to the doctor?

Could I still have a respiratory tract infection, even though I have no fever, and cough has subsided a great dealt. Is it o.k. to wait until Monday, tomorrow, to see doctor?
