Hello Teresa, It sounds like you’ve had such a horrible year since being diagnosed with Immune Thrombocytopenia Purpura (ITP). It’s awful when you feel like this and have anxiety running the life.

ITP is a blood disease caused by the body’s immune reacting against its platelets. Sometimes the cause isn’t known but there are factors that can trigger the response to happen.
Medications, infections, typically viral infections, including chicken pox, hepatitis C, and AIDS, Covid, Epstein Bar virus can prompt antibodies that cross-react with platelets.
There are Immune disorders, such as rheumatoid arthritis and lupus
Low-grade lymphomas and leukemias may produce abnormal antibodies against platelet proteins.

You may never know the cause of your reduction in platelets. But it’s clear something is going on with your immune system to have you feeling so sick, dizzy and achy all the time.
It sounds as though you’re getting routine blood work run but have you had any other tests run to check for auto immune diseases, a bone marrow biopsy to check the health of the bone marrow…which is the blood manufacturing center of the body?
When your platelets are low, you can have excess bleeding with cuts and bruise easily. Does this happen to you? Has any medication been recommended to help slow the progression of the disease?
