Don't be afraid, the treatment out weighs the side effects. I trust my Dr as I am sure you do yours.I think it may be different for everyone.I experienced some pain, yes it was jarring sometimes but I did not let it interfere with my daily life. In my experience it sometimes felt like a quick jolt of lightning or the occasional muscle ache that tended to travel through different body parts. My daily mantra was always, a body in motion, stays in motion. I will be 59 this summer and I work full time, and I blame it all on my treatments!! Lol !!! Not the fact that I am older😂😂. Keep a positive mind set...it's a pill you take once a day and carry on. I am thankful, I am here to enjoy my granddaughter. She keeps me busy!! I do find that I run out of steam a lot but keep plugging along. One foot and one day at a time. You can do this!!💖
