Suggest Treatment For Mycoplasma Causing Recurrent Fever And Dry Cough

Hello . My daughter is 14 yrs and plays tennis on a very high level in Sweden. She got sick last fall. Extremely tired and a dry caugh. Went to the doctor 4-5 times before we finally, in januari, found out that she tested positiv for Mycoplasma. The doctor gave her antibiotics Ery max. She hade a hard time to come back but finally, in late spring, she was OK. After a tournament in late june she got sick again - caugh and fever. She was OK after 1 1/2 week. Summer was OK and she worked hard to get ready for the swedish championship end of August. She played great and finished 3rd in both singles and doubles. Again after the championship she got sick again and for the 2nd time she tested positiv for Mycoplasma and got treated with antibiotics -Doxyferm 10 days ending 2nd week of september. She was OK until middle of last week ( december 1) when she again got extremely tired and the dry caugh was back. Mycoplasma again?????? I feel so sorry for her and don t no what to do.
