Suffered from severe sciatica for 2 weeks, extreme leg and foot pain, foot pins and needles, my foot sole still feels like "sleeping" i developed a itchy rash with blisters along my foot where the most pain was, could it be contributed to xtreme pain?

Might be related: Skin pain can be from one of several possible causes. A doctor's exam is needed (primary care doctor or dermatologist). A person with shingles can have burning pain of the skin where the rash breaks out. Sometimes nerve irritation (anywhere along the nerve from the spine to the skin surface) can cause pain sensations in the lower back, thigh, or elsewhere. An in-person or video exam is helpful.
