Hi, I am 50, and have had 2 sessions of botox. My feet have gone numb, yet my sugar lvl are great. And I have had 3 episodes of well, suddenly it s like my bones are gone from the hips down. No pain, a small about of pressure on small of back is the only warning. I can still move, no pain, but I can t walk w/o holding myself up. I am wondering if it could be a side effect of the botox. I am also on 20 mg of Oxycodone twice a day.
