Vertigo. Treated For Carcinoma Multcentric Stage III. Administered With Fragmin Injections Daily And Neupagen Shots. Problem?

Hello, Thank you in advance for your response! I am a 40 yr old woman currently being treated for inv.ductal carcinoma multcentric stage III. I had my 3rd cycle of neoadjuvent FEC chemo last Thursday 8 days ago. Chemo nausea subsided and taking no meds other than 0000 IU Fragmin injections daily (past month) for a large Blood Clot running from inner elblow ending at arm pit. -pic line(now removed) - I am also taking (past 6days) Neupagen shots. *** my question or concern today is regarding vertigo. I awoke this morning @ 1 hr ago with loss of balance and blurred vision. Feeling like I had too much to drink on a tug boat in stormy waters. I almost went head first into a wall before catching myself. So naturally I m concerned about a mini stroke precursing a massive stroke or hopefully perhaps low hemoglobin. My symptoms improve when lying or sitting still, but worsen with movement. I m hoping I don t need to make a trip to emerg. for a six hr wait. Thank you
