Hi and welcome,
You asked "what do these symptoms sound like" and i can really only explain that what you've described is situation specific, as in you only experience these symptoms when you did X but not Y ....
"2 months ago started having pins and needles in thigh. This was more likely when seated. Then the pins and needles seem to involve the shin on same side. The Symptoms would come on when driving or laying down And settle if standing and walking"
...which is not suggestive or consistent with a neurological condition like MS.....its more what you'd expect from a temperary peripheral nerve compression / circulation type of situation.
The problem with a temporary peipheral nerve compression /circulation explanation though, is that your saying it has completely changed to all over and quite rappidly if this only began 8 weeks ago...
"Then the symptoms become burning sensations on both legs mainly front of legs. Again improving if moving. The symptoms of burning or prickling and crawling started and would last seconds or mins. They would seem to be face, neck, chest,back, thighs, shins or feet. There seem to be all over the place now."
Anything like this that's only lasting seconds / minutes is unlikely to be related to something like MS because of the way MS caused symptoms develope.
One thought is that it possibly started off with it being more suggestive/consistent with a pheripheral nerve related issue that disapears with movement and if you do tend to assume the worst and then with googling stmptoms and or medical conditions, it 'might' of fed your health related anxiety and that has caused your symptoms to change and reflect your anxious your feelings.....something to consider.
Hope that helps......JJ
