Hi Ana, and welcome!
Back pain has been one of my constants. When I need it I take either bacolofen or Zanaflex. MIRACLES! I try to not take them on a regular basis, and save them for the truly tougher days.
Any symptom (sx) lasting longer than 24 hour straight with no breaks, needs to be reported to your MD. it could be the sign of a flair. You have about 10 days to figure out if you want to accept steroids IF it is a flair, and after that 10 day period, the recovery rate for those who took steriods vs those who didnt are about the same.
they have icy hot gels, heating pads (be careful because heat can trigger MS stuff) massage, chiropractor, yoga, stretches, visualization and meditation can also help.
