I am a 25 year old female and for the past 6 months have been experiencing the following symptoms:
-Hear blood flow in right ear
-Left arm and leg go numb - feels like no blood flow, pins and needles, then aches - this mostly happens when I lay down or if I sit in one position too long
-Lips and tip of tongue will go numb/prickly
-Last night- awoke from sleep feeling as if I had been hanging upside down -- I was laying on back, whole left side of body felt numb again, vision felt grainy, felt like all of blood had rushed to my head
-Lots of heart palpitations- especially when I lay on my left side


I have been to my PCP and a neurologist over past 6 months with following tests/results:
-PCP did a blood flow test and said it was "borderline" on left side and "almost borderline" on right side--though did not recommend any treatment or explain a cause-- told me I was too young to worry about it.
-All blood tests came back normal
-Stress test result normal
-Neurologist- MRI scan of neck (about 6 months ago), results normal

My question:
-I continue to experience significant symptoms that are scary, especially last night. However, my health insurance expired last month. Are these symptoms something I need to continue to worry about and seek immediate attention (despite not having insurance)? Or am I being paranoid and can wait until I can afford a new insurance plan?
