It is certainly possible that you had Mycoplasma, such as M. fermentans, M. pneumoniae or M. hominis. M. fermentans is the most common co-infection with Borrelia burgdorferi in Lyme Disease, and it can be found in ticks with or without Borrelia. It can cause all of the generalized symptoms found in Lyme Disease and certainly all of the symptoms that you listed, and more. Mycoplasma species are difficult to test for, and this usually requires a PCR test on blood leukocytes (white blood cells). Only a few commercial labs, such as VIP Labs of Reno, know how to test for Mycoplasma infections, and even labs that are very good at Lyme testing, such as Igenex Labs, can’t do the Mycoplasma testing. It is also a possibility that you actually have Lyme Borrelia, but the testing was not sufficient to find it. Usually multiple tests are required to find Lyme Borrelia, and many commercial labs that claim they can test for Lyme Borrelia do not use optimal testing procedures, and thus their test results are not all that good, and they miss positives in many patients.

Most patients have to change antibiotics at least once during long-term treatment for systemic mycoplasmal infections. Recovery is slow and gradual, so don't expect a rapid recovery. ProfGN
The ELISA is a very poor and unreliable test. It is about 40% accurate according to what I have read. The western blot is more accurate. You may want to see a doctor that specializes in treating lyme disease. This way you can get an good evaluation and accurate diagnosis either way.
Do you live in a lyme endemic state?
I did not have any lesions but also had a tick bite, bullseye rash, MS-like symptoms and was told from a major, well known facility that they had "no idea" what was wrong with my central nervous system.
