For The Last Week I Have Been Experiencing The Typical

For the last week I have been experiencing the typical signs of a summer cold , sore throat , stuffy nose, small cough. Then three days into it I had stomach cramps ,diarrhea, the feeling of being totally tired and run down. Then I started feeling like my joints were swollen , last nite I could barly sleep because my wrists felt swollen and they ached all nite. Today I feel totally tired and sore all over. Would it help to see a doctor or is this something that could just run its course and be done? Thank you!
