Yes, West Nile, Lyme Disease, Rocky Mountain Spotted tick fever, allergic reactions, De Quevarains tenonditis. You should really go back to your physician and be tested for West Nile and Rocky Mountain Spotted tick fever if you live in an area where mosquitos and ticks are present. The rash, fever and chills is what is making me think of these possible diagnosis. Also have a CBC done to see if your white blood count is elevated. Either way, you need to see a doctor and if they do not listen to what you are telling them or refuse to test you, please seek a second opinion.
