Yes you can have a negative blood test to lymes decease before and after iv treatment. Follow up with your doctor. If the doctor diagnosed you with lymes decease, you must have some of its symptoms such as tiredness, weakness in muscles and joints followed by pain, headaches, vision problems, etc. This decease is very serious. It affects many different areas of the body. If you are feeling better--great. Keep following up with the doctor. Lymes decease does not go away, it goes into remission and can come back in the future. God Bless.
