Emergency Medical expenss.

ok. I am still in the hospital. As I had posted I fell the other day and bashed my head in the middle of the night. Didn't even know I did it. Just had a screaming head ache that happened for three days every night just after I went to sleep. My face was hurting but We thought it was sinuse's bother me. Even bought Sinus meds.. The third day I had an appointment with my doc anyways and they seen I had a head injury. So now I know I fell a week ago. Had a cat scan and it was ok.. But the head ache got worse and they admitted me in the hospital. And my Cardic Doc wanted to do a Cardic Cath to check on my stinting from a month ago because I am still having chest pain some.. I have what is called Cluster head ache's.. From the fall. I have to be on Oxygen for it. Somehow it makes it better. When it starts hurting I have to be on 100% oxygen.. Its going on my 4th day in the hospital and they are sending me home tomorrow. But I need the machine for the Oxygen and my Medicare wont pay for it. They are telling me it will be 2 or 3 hundred bucks for the 4 to 6 weeks I need it. I am going to have to start a gofund me I think to pay for it.. Not sure what else to do. And my heart Cath was ok today.. But you have to not more for 3 or so hours after, its in you Femoral Artery. After the time was up I got up and BLEW the dam artery.. Blood everywhere..l lol. So I am not allowed to move for 6 hours now.. I have two and half to go. Dam... I will start that go fund me asap.. Hate to do this but they said I have to have it.. and tomorrow... Dam.. I will add it here shorty. Please help If you can... Sorry..
