Should I be worried?

I'm not a Dr. but will give some input. The symptoms in the front or outside of your thigh could be a few different things. The obvious is spinal involvement on the Femoral or Lateral Femoral Cutaneous Nerve. This could come from L3/L4 or L2/L3.

Another cause is entrapment of either of these nerves at another point outside the spine. Such as entrapment at the inguinal ligament to your Hip (ASIS). The referral pattern being the front and side of your thigh as well as your hip. Google Meralgia Paresthetica.

As for the numbness on your arm, it could be anything. Stress can be a big factor and one I wouldn't overlook as your working thru your current situation.

Again I am not a DR. and I would recommend talking to one about your symptoms.
