I stopped taking the doxy around 8/20/06 and continue to have symptoms. I was on the abx for 3 weeks. Since then I had migraine headaches for a week, and now I have nausea, headache, blurred vision, pain in soles of feet, etc. HELP! Should I go back to the Doctor (GP - wasn't too helpful), find a Lyme Doctor, or will these symptoms go away by themselves? I'm worried !!!!!!!
