As Alexia said, different symptoms show up in different people which is one of the reasons Lyme is extremely misdiagnosed. There are no "set" of symptoms as they vary from person to person.
As far as 1 month of taking antibiotics, no, that's not enough time kill the lyme bacteria's as they have their own cycle, but that's another story by itself.
Lyme bacteria's or spirochetes are the most difficult bacteria to kill, they change shapes, hide in places where antibiotics can't get to them, form cysts to protect themselves, etc. They are very smart!
Lyme is really a disease of the brain unless treated within a couple of weeks after being infected, if not, those bacteria's cross the Blood Brain Barrier causing neuro problems.
I would ask your doctor to send your blood to one of the Labs I mentioned above. The QRibb test done by Bowen is very accurate. It also wouldn't hurt to see a lyme literate medical doctor (LLMD) as lyme is also a clinical diagnosis as tests are never 100% accurate as Alexia also stated.
There are so many ignorant doctors out there when it comes to Lyme Disease who don't take the time to educate themselves so sometimes we have to be our own advocate. The "average" doctor usually says "lyme doesn't exist in this state" or "it's all in your mind" which is totally false.
Lyme exists in every state and every international country. I have friends from all over the world who have lyme.
I hope you pursue this as if you do have lyme and it goes untreated, it progresses with time and gets worse. I don't want to see you or anyone else get to the point where it becomes really difficult to treat.
You also may want to buy the book called "Everything You Need to Know about Lyme Disease and Other Tick-Borne Disorders" (2nd Edition) by Karen Vanderhoof-Forschner as education is one of the best defenses toward this disease.
Also, here is an article published by my friend Jon who was misdiagnosed:
Good luck to you!
