My Levaquin ADR happened 13 months ago. I still have many neurological and neuromuscular symptoms.  I was given doxycycline for a skin condition. If I only take 1 pill I get major head pressure and all my neurological symptoms flare up big time. If Levaquin supposedly caused me to have nerve damage, then why would taking doxycycline bother me at all. I am not currently taking any of the doxy, but was just wondering if any one might be able to help me postulate about the observance. I would appreciate any comments
