I had my iud removed 4 weeks ago due to serve back pain and headache. After removal the headache went away and the back pain wasn't so bad. Now Ive been on the pill for 3 weeks and for the past week the back pain and headaches are back along with sore breast and cramping. Ive taken pregnany test and they are negative so I'm not pregnant that god. Also nothing is helping the pain Ive taken ibuprofen Tylenol and Excedrin pain. I'm question is does anyone know what could possibly be going in with my body? Please help. I don't have insurance so I can't go to a doctor unless I pay out of pocket and I don't have 2000+ dollars to spend for nothing. Thank in advance.
