Thanks April for the further information.
Your symptoms are suggestive of viral bronchitis. This is likely to resolve on its own, though an examination by a doctor today and a chest x-ray would be advised for the confirmation. Following also would be recommended for the nose blockage and sore throat;
1) Nasal steroid; decrease inflammation and open up obstruction.
2) Oral decongestants such as pseudoephedrine are often helpful.
3) Topical decongestant for short duration.
5) Steam vaporizer
6) Eucalyptus oil may help
7) Nasal saline irrigation
8) Vitamin C
10) Warm saline gargles
Your doctor may also do a swab test if the sore throat is persisting and get some blood work like complete blood counts.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
Thanks for using Just Answer.
