Bump from tick bite

[mattmtv]

I was bitten by a tick about a month ago was told I had Rocky Mountain Spotted fever, I never had any of the symptoms but I was on doxyclin.  I still have a bump where I was bitten by the tick, it doesn't hurt or itch but it is just there.  I am not sure if this is something I should be concerned about.  

Thanks.

How did they make your diagnosis?  Most bites do not cause any disease.  Unless the tick stays on for several days it is unlikely that you will have tick-borne illness.  It is not uncommon for the bumps to remain for weeks or months.
