The cyst is of 4x4 size on my back with a small bulb on it. Going through the treatment since a week where I consumed enough antibiotics but no go n the cyst remains the same now the antibiotics are going through veins today being the second day of the course of three days. The cyst still remains tight n solid like a muscle lump on my back. It's been more den a week where doctors are using there trial n error method and giving me a run around with no positive assurance. Kindly help me on this and advice the right way out.
