Unfortunately, these 'common symptoms' often do not occur after an infection, so this is misleading. In never had them but was positive for Lyme after dealing with joint pain for quite a while. Taking a single dose of Doxy is usually recommended if you live in an area with high prevalence of Lyme in ticks [1], and if the tick was not cleanly removed within 24h. The latest meta study I'm aware of showed that this will reduce the likelihood of infection by about 70% [2].

The fear of breeding a MR Borrelia is completely overblown. By far the highest risk of breeding MRSA are in a hospital setting, not by taking a single dose of Doxy at home. The main reason to not take Doxy is its side effects (for instance, when I had to take it against my Lyme infection, I vomited like there's no tomorrow, which fortunately is one of the lesser serious side effects. Had to switch to Amoxi.).
