I have had minor cuncussions in the past. Last one prior to this was about a year ago. Now had a major fall at work resulting in loss of conscience for unsure time frame. Spent days in hospital had ct scans and mri all negative. Workers comp nurse wanted me to go to inpatient care. But drs sentence home. Have major headaches. ( never had prior) very unbalanced memory loss , irritability, sensitive to light and trying to walk up a flight of stairs. Fallen twice. It's been almost 3 weeks and nothing is improving. My fear is my job and the ability to perform it safely ( currently still out of work) I am an Hvac technician which requires me to climb ladders,go into dark attics back to bright lights and working around 240 volt electricity. This is all I've done for over 20 years. My home health nurse insist I should be better and without directly implying my symptoms are in my head. Even asking us if we were financially challenged are we paying our bills or filing for bankruptcy. Any suggestions sorry for rant.
