Heya i have been suffering with severe kidney infections for the last few years. However i think it may be cystitis . I have the implanon bar now in my arm 2 and a half years. It has only dawned on me recently that the implanon may be the cause of it. I suffer from these infections many times through the year and it seems to come more often when I get my period. What actually happens is I can feel the kidney infection/cystitis/ uti coming on and I get excrutiating severe pains. These pains would start inside the opening of my vagina, it would effect urinating as sometimes it would be sore, i would feel like i have to urinate often. But most of the pain is inside my vagina and i get very sharp pains coming from my lower abdomin and all around my vaginal area inside. Usually within the next day or two i would get my period. However this is not always the case. I am getting very worried as the pain i experience isnt natural. I cannot go anywhere or do anything only stay in my bed with howater bottle. I am very concerned as I am only 20 and I can get many of these infections throughout the year. Also, I think sexual intercourse may not be helping as sometimes when i get these infections I would have had sex a day or two before hand. I really want t fing a solution to my problem, I take anti-biotics for this and although it clears the infection up in about a week or so the problem is still there as these infections are reoccurring regularly. I was wondering could the implanon bar be a cause of this? and if so I might change to the pill? is there a recommended pill for bladder/kidney/uti infections???
