I have been feeling like I have a bug for about a week. Head stuffiness, weak in the legs, fatigued, light headed, nauseous. Have had many blood tests and all seems to be ok. I have implanon in my arm for birth control, which I ve had almost 2 years. This is causing problems in my daily life as I am a single mother of 2 working full time. Any suggestions would be great. I do have issues w/ anxiety. Going to doctor on Friday but sometimes I feel they don t take anything I have to say serious b/c I haven t been feeling good for some time but they always say I m fine. Thanks!
