Severe dizziness from methotrexate your experiences?

I have been off methotrexate since June 1 because of very severe dizzinessThank you very much for any information that you could give me which no doctors can figure out what the causes are. I still have the dizziness even though it’s a teensy bit better than it was. Any information you can give me would be very very appreciated as the doctors are completely clueless and I have been to many many doctors!!! thank you!!!
