LWP on medical grounds ?

I am on WFO exception because of my medical condition (I have high liver inflammation). I took WFH for 2 weeks and they are not willing to let me extend my exception more than another week despite me having valid medical certificates including blood tests, ultrasound, and endoscopy.

In this case, would it be possible for me to avail LWP for 1-2 months ? I completed one year in TCS in June this year if that matters.
