My Husband And I Both Have Felt Really Bad For

My husband and I both have felt really bad for an entire week. Neither of us have had fever, when we've checked it. We neither have ever felt so bad before. We ache all over. Seems like muscular aches and pains but I don't know, I have allergy symptons, but Ive had these before but never with this type of bad feeling.. When we move around in the slightest amount, we get severely short of breath. no blood coughed up, but thick sputum.It is just what I call general aches and pains and feel horrible. Do you have any idea what we should do of what we can have?o
