My Back Pain Has Been Ruled Out To Be Sciatic Nerve

I went to visit my doctor the other day and I told him that, my lower back pain is unbearable and its an aching pain which is hitting all the way to my toes. He checked it out and he said that I have sciatic nerve and he said my back isn’t fully straight. I started to freak out a lot and I just got scared about it. So my doctor is going to send me to a chiropractor and I am going for massages for my lower back. I am so happy they approved it for me to go have these massages done. It is unbearable. When I stand up or lay flat, nothing happens and It is good and I don’t feel pain, but as soon as I sit down, The pain just rushes down to my toes and sometimes Its so painful that I end up sleeping it off. After 10-15 minutes of sitting, the pain starts again. The pain is hitting my abdomen pelvic area. I do have UTI (urinary tract infection), but I am going for an ultrasound and Cat Scan to see what is going on and to further it. I just need to get to the bottom of all this. I can’t do much when I have this pain and its terrible. I want to be able to not feel pain anymore. Its a chronic pain that keeps coming back. my thighs, my feet, my toes. all hurt as a result for lower back. I need to relax today and lay flat… I will see with what happens from here.
