I had my infusion on monday 20th April. The next day I couldn't get out of bed with the aches , thumping headache,watery eyes and listening to my blood pumping through my ears. Had that all day and some of the next day. Thursday was fine even went out for lunch. Then Friday woke up with another headache and pretty much the same as the day after having the infusion. The only difference  was that I used a medi pot to flush out my nose and nose spray today but made my headache  worse. So i have stopped it now. Been taking paracetamol  and ibuprofen and drinking lots of water but the headache is still banging and now have some earache. . Anything else I should do as I am near to ringing the hospital. Because  ive had problems  with my sinuses my doctors think Ive got the side effects of infusion and my sinuses going on.
