Sorry you're not feeling well Tyson. The only advise I can offer is that you contact the doctor that prescribed the antibiotics and perhaps he/she can prescribe a different one. If you have an infection it needs to be treated to to help eliminate some the of symptoms you're discribing. Sleeping with your head elevated as suggested by Kate I think, will help you breath better due to the stuffiness. Sorry I couldn't be of more help. Take care and let us know how you're doing.
Hugs,
Pat
