Hi,first of all ,no reason to apologize,we all are looking for answers. I have had POTS for 4 yrs. and still don't get it. For me being dizzy and lightheaded is normal most of the time,sometimes are worse than others,but is never completely gone. There are of course meds. for the symptoms,but unless my symptoms are severe(and sometimes they are)I prefer not to take the meds. As far as for the the numbness,mine is usually right-sided. Take care,Hugs Pat
