I fell off a horse about 1 month ago and i keep haveing muscle spams and pain on in my left back where my kidney is located. I have had exrays notheing showed up but the pain has not gotten any better. the dr. gave me cyclobenzaprine 10 mg. and mexloxicam 15mg this does not seem to help i had some hydrocodone and have spaced it out to taking i/2 pill morning an d 1/2 pill at night . Im afraid to take to much but its the only thing i have found to work .i do have Lupus my Dr. out of the country at the moment.
