You need to see a medical professional ASAP. You think Sun squares will fix your spine in a month or a year? You are just procrastinating and doing everything possible to not see a doctor. You will only get worse like that, not better.
I myself live in a place where you can say there is no medicine, and what can really help costs so much money that while you earn them you will definitely die.
No one will advise you to try to heal yourself with the help of magic, if you have the opportunity to get medical help, but if your situation is really desperate and you are not just lazy or do not want to - you can try the square of the sun, rituals of Valefor, Asclepius, try to work with golden energy programming it for healing. Here everything will depend on your personal magical power and it will be better than nothing.
