Need Advice Asap!!!!`

Two months ago I experinced numbness through out my body. I could not breath and had dry mouth. I went to the er the next day. They ran a blood test,urnine test and xray all was normal. The doctor said it was not a stroke or heart problem. Now 2 or so months later still having same trouble from time to time also having pain in my right arm. I am now also experiencing dizzyness from time to time. My nose also bleeds from time to time when I blow it and also when I sneeze. Its not alot but it scares me. This er doctor sent me home and told me nothing is wrong but I feel different. I can t afford dr's as I have no insurance. Ive posted this add 2 times before and recieved no response. I do have dental problems as my teeth are in very bad shape. Every morning when I wake up and I wipe my mouth all this brown stuff comes off my lips and my breath is real bad. I have a rotten tooth with a exposed nerve and many other problems. I just have no money or insurance. I wish I knew what to do??? I pray and pray and nothing changes. Im really scarid :cry: :cry: :cry:
