Hello Pinapple Princess! First off welcome......in reading what you posted sounds like you have a pinched nerve.
Never worry about seeing a Neurologist or Neurosurgeon.....prepare by outlining where your pain originates, travels, is located, when it occurs, which position is best for you and research the - sounds like L2 area of your spine - a pinched nerve in the L2 area usually results in upper leg pain (either side), trouble standing etc.
Sounds like something happened around Christmas to aggravate the nerve....it has been three months since the "occurrance" so when you see your Neurologist do not be surprised to start the second phase of "Conservative Treatment" which may include physical therapy, massage, swimming for exercise and medications (if they are helping) You are in a flare and using the principals of PRICE (Protect, Rest, Ice, Compression, and Elevate) will help you - take it easy, I know it is hard to "compress" our backs but there are ace wraps, the object is to steady the area......
My doctor even suggested a back brace for me at one point (My orthopedic surgeon said not to use it though)
I have been living with about the same condition you have but the L5-S1 thru L-3 are pinched nerves, herniated and at the L5-S1 area a nerve narrowing and Spondylosis (arthritis) at the L5-S1 through the L3 disks......that's just my lower back...some days are miserable, use a cane but cope......that is important coping. Finding a site like this one is helpful - the advice I have recieved on this board has been very valuable.
