i have my implanon in my left arm and my arm is always getting this tingling numb feeling along with pain... the pain and numbness is not near the insertion of the implanon... its on the lower side of my tricep and it goes from my shoulder all the way down to my elbow mostly and some times it goes down to my forearm ( but the going down to the forearm isnt very common). is it a sign of being cracked? or is it getting pushed into my muscles? or what is going on? i just want to know if i need to get it removed... i got it put in january 2011... it has been hurting now for about 3 months now... it mostly hurts and goes numb or tingles when im sitting in the car and i bend my arm or typing on laptop keybord... etc... things like that... please help me i already have grade one retroliesthesis so my back is screwed up... i dont want my arm to get screwed up also... thank you... P.S. if you need any more info just ask me... i can try to give you as much info as possible... thank you again...
