I'd get a good cardiac workup and a B12 level done.
I worked with an Indian woman whose young sister (30's) had similar problems on the left side. It turned out she had a cardiac problem and also causing it all was very low B12 (she was a vegetarian like many people from India are).
Your B12 levels should be 500 or above. In US they still use antiquated lab scales that go down to 200 and if you are down there you are having problems with that low level.
I have a B12 thread on the PN forum since many of us use it for neuropathy. It has all the details:

Not all left sided weakness is neurological.
