Hints
Get diagnosed by a rheumatologist not the interweb. transient polyarthralgias are common after a viral illness and it may settle spontaneously if you are lucky ( 2 week history so far right)
However if your inflammatory markers are raised significantly and clinically you have a new onset RA then you should be referred urgently by your GP for specialist investigation and treatment. If you hear nothing over the next month or so make a nuisance of yourself with your Gp and hospital 1st appts office. Don't take my word for it it's in the latest NICE guidance on referral guidance.

basically if you have RA early treatment with disease modifying anti rheumatoid drugs and immune modulating drugs is giving better and better outcomes. However early diagnosis and treatment is the key. Good luck.
In the meantime take high dose antiinflammatories!
