yes these are all symptoms that you can get from mirena. i had the facial numbness, and left side numbness and a dragging down feeling on the left cheek. it also started off a terrible pain in my head, which developed into migraines (never had them before). These symptoms and more are all listed on the official mirena info and various other drug sites, under the WARNING section - one such site is as follows - please print it out, circle all your side effects and take the pages to your doctor.
Mine took the mirena out there and then when she read the information and saw that the symptoms i was having were what was on the printed page. She also sent me for a head scan to be sure, as she thought i may have had a mini stroke with the mirena. please get the doctor to take mirena out of you immediately. these symptoms are extremely dangerous and will most likely only get worse. It has been 2 years since mirena was taken out of me, and although I am a lot better, i am still not completely ok and the whole episode has left me with left sided head pain and occassional migraines. good luck and stay safe.
