Eliquis and dvt

Do I need to be on eliquis lifetime for post surgical DVG? Never had a problem until I had reverse shoulder replacement, developed DVT five days later. All blood work perfect now. Still being told will be on this for life. Was placed on metropol, losartan and eliquis . These makes me feel awful. Have never needed medication before now. Do not have HBP. Not getting clear answers only that I was very sick.
