Muscle tightness. Will be of any help?

Hello sir , from past 2 year , I was experiencing muscle stiffness which started from neck, then hands and legs , also pins and needle feeling in whole body,doctor told for MRI BRAIN which was normal then he gave b12 medicines , but day after day my symptoms increased more stiffness in whole body feels like my body has became stiff , chest stomach everything feels very tight and then sometimes cramp in chest started and breathing felt like a little difficult when I am in pool or singing a song , really all this feeling has spoily my life, all day I feel so weak I cannot express that. My blood markers are normal like lft kft cbc crp , one doc suggested to meet neurologist for muscle disorder as now feeling in chest muscle is so bad from past 8-9 months that I cannot sleep properly . Due to lockdown , I am in small town and no neuro is here , can consulting with neurologist online will be of any help?
