I suffer from a huge blood hemorrhage for about 3 weeks after every injection. It is not painful. The doctor told me it is because I get a blood thinner medication (LIXIANA 60 mg.) and the needle probably touches a vein in my eye. can't find a solution to this very annoying problem of having a terrible red eye for 3 weeks !!! . I get an injection of EYLEA every 2 months for a wet MD.
