splenectomy

I had a splenectomy 21 years ago due to primary CMV induced ITP refractory to steroid treatment. I received the preventive vaccines , pneumonia shot, yearly flu shots. Over the past few years I have had sinus infections, eye infections,that last over a month each taking multiple prescriptions to finally clear them. Since april of this year, I have had recurrent sinus infection and severe fatigue and presently have an eye infection that has been going on a month. I just can't stay well. I am an RN on a med/surg floor 13hour night shifts and have missed a lot of work. The work is very high stress I think the immunocompromise from the splenectomy has finally caught up with me. I am 60 years old and thinking of pursuing disability. Thoughts
