I Just Finished Two Rounds Of Antibiotics. One Was For

I just finished two rounds of antibiotics. One was for a bacterial infection due to a sore on my leg and the last one I just finished was for an upper respitory infection I just got over. this as all in the span of the last 3 weeks. all the infections cleared up and I feel great except for the cough which is always the last to leave, but I haven't got all my taste buds back and have a metal taste in my mouth from time to time, is that just from the anti biotics??
