Muscular pain, feel unstab. 2000 now!

I recovered from vitamin D,vitamin b12 deificiancy about a month back.everything was getting back to normal smoothly.but when weather changed i started getting muscular pains all over body.some areas stiff,others numb. Took robinaxol 5 days..improved situation by 30-35%.main issue is i feel bit unstable when walking,running...breathing is bit odd too( i am more aware of my breathes).massages and epsum salt bathes make little difference. Was diagnosed with vit D,b12 deificiency,very high ldl( which is 61 now),spondylitis... Everything was ok till weather changed..was doing cardio everyday too.. Now crackling sounds all over body..feel weird pressure on shoulders and neck..sometimes i feel like vomiting but absolutely no vomit.overall i feel weak.. Doing yoga twice a day ,stopped cardio and continuing statins 5mg..was on vitamin D satchets for 10 weeks..b12 above 2000 now
