Thanks for reading I used make an operation to cut off a lump on my waist I went home 1 week after that, and I was told to visit back the hospital for injection once. They injected my butt with some substance, that I barely walked straight right after that. It's terribly painful. This injection is known to be a mustdo for all patients with open/cut wound, the doctors claimed it helped heal the internal injury. Does that substance have a name ?
