Is It Possible to Get an Oxygen Cylinder?

I had a devited semptum on my left nose, so there was problem in breathing and all. I told the doctor, but he ignored i don't know why. On fifteenth may, my oigon was above above iting 94, and they discharged me. But there was severe headache on particularly on the left side. It was like as if someone wis piercing needle or pricking something. When i got up in the morning on the sixteenth May, it was all swellen very badly. This post off left a left face. The e nt specialist told them that he has this and this is very serious. He told them clearly that this may be life threatening
