Fragmin

Does anyone have experience of lung clots treated with Fragmin?

I was admitted last Monday with severe breathlessness. I have a chest infection and blood clots showed in CT. I’ve had 5 Fragmin jabs (one a day) so far. Still breathless and unable to go home, but the chest infection is resolving.

Does anyone have a similar experience and how long did the Fragmin take to make a difference?
