Hi I Have DGI, And I Haven't Healed With, Ceftriaxone

Hi I have DGI, and I haven't healed with, ceftriaxone I.M. , penicillin G I.V. , cefixim, It took half off when injecting penecillin G again I.M. this time. then switched to trobicin, which healed my urinary tract but not my dermatitis and arthritis. Then swithed to ertapenem with no affect at all. Now I'm taking Augmentin orally and feel some stinging on the infected sites both in my joints and under the rash of the dermatitis.
So could augmentin completely heal DGI. and how many days should I take it then. Or is there a better agent that has no issues with resistance? thanks in advance.
