I would like to know the best treatment for an inflammation to my left buttock that started 3 years ago with an excruciating pain after long sitting hours on a cemented floor of a bakery where i used to do packaging duties on doughnuts and other cakes and in time got inlammed with a lot of pus that has refused to dry up even after several antibiotic prescriptions most of which I turned out to be resitant to but even the one that my body did accept did little to improve my situation.The most debilitating thing is that this pus has  stayed too long in my inside buttock and oozes out everytime I walk a distance or sit on  a bench with the result that it wets my pants all the time.I have difficulty  moving around as well as it pains a lot.Further i began to develop hip bone pain to the right after a year or two within the first inflammation so that I have  a feeling that I no longer can rely upon my limbs to support me in mobility.All the medications I have received have been of little help and I strongly suspect that my two conditions might be related to each other. I have a long standing history of a back bone injury sustained during chilhood although I have never used crutches before.Please advice.
