Good Afternoon

I am struggling. I have had 3 surgeries (including four compartment fasciotomy) and a procedure for clotting in my leg since a bout with COVID several years ago. My doctor is sure that this is covid related. I have also been anemic and suffering with bouts of low hemoglobin for over a year now and have to have periodic blood transfusions. I've been tested by just about every specialty possible and no one can come up with a treatment. I am taking two Eliquis and 1 low dose aspirin daily but can't do triple therapy because of my blood loss. Does anyone know of any studies that are currently being conducted that insurance will approve?
I meditate and pray daily, volunteer with two non-profits, paint and spend time with family and friends. Doing everything to remain positive and to give back but some days keeping optimistic is hard.
