Hi and welcome,
It's highly unlikely what you've been experiencing is going to be caused by a neurological condition like MS if your MRI is normal, MS literally means many scars and if you don't have any suggestive-consistent brain and or spinal cord lesions your MRI diagnostic evidence is a red flag pointing away from neurological conditions like MS.
Your symptoms pattern of "tingling sensations in my hands and feet" is happening in all your peripheral limbs (bilaterally and in both upper and lower neural pathways), this is not a symptom pattern typically suggestive of neurological conditions like MS.....symptom patterns that are in all peripheral limbs, symmetrical, move around from one location to another, spread, rapidly develop or multiply, appear in random locations, all over the body etc are also some of the red flags pointing away from neurological conditions like MS basically because of the way MS lesion damage presents and develops over time.
In regards to having a family member diagnosed with MS, it's actually more common to be the only person in your family with MS than to have multiple family members diagnosed, though it does happen it's not typical. Genetics are only 1 of the things that could slightly increase your susceptibility and the further removed your are the lower the genetic relationship so the lower the relevance that family members MS diagnosis has to you ie the person with MS is your grandmother, grandfather, maternal or paternal aunt, maternal or paternal uncle, 1st-2nd-3rd cousin, half brother, half sister, etc.
You don't mention if your neurological assessment showed up any clinical abnormalities or not but if that too wasn't abnormal, your diagnostic evidence is basically all pointing away from neurological conditions like MS, that doesn't mean to say there isn't anything medically wrong, just that the alternative medical explanations are what your more likely dealing with...
I hope that helps.....JJ
