pains in mid back, arms, blurred vision

Ok about 5 years ago I started getting pains in the mid back area, went to gp (wste of time, I think I must talk a different language) the pains have got really bad now, pains in the tops of my arms, blurred vision(couldn't recognize my sister from 10yds, some days vision not as bad, burning sensation in the tops of my legs (thighs) lightheaded and often a whooshing senstion ( like the waves as they drag back down over shingle on the beach) from time to time arms have felt numb when I wake, get pins and needles in some of my fingers, when I walk sometimes I get a tingleing sensation all the way up my left leg from the foot up. extreme tiredness and now geting quit depressed. do these sound like symptoms of MS and how do I get my GP to listen,?
