4th Year. Is that WSU, Michigan? Spent many years there. Two things: 1; Please carefully read what you can regarding your concern. 2: Once read, please discuss this with doctor with whom are following. He/she will help to the extent possible or refer you to a specialist. Hope you learn a lot! PS: Enjoy graduation !
