Hi
Welcome to the MedHelp forum!
A pain, tingling and numbness of this type can be due to two main causes. One is deep vein thrombosis—can be diagnosed by duplex ultrasound or color dopplar. This you must get ruled out first as you have a family history. The other is pinched nerve or sciatica. This can be ruled out by MRI of lower spine.
If both are ruled out then peripheral neuoropathy as is diabetes, hypothyroidism, and Lymes will have to be looked into.
Take care!
It sounds like sciatica from from you lumbar region. The term sciatica describes the symptoms of leg pain and possibly tingling, numbness or weakness that originates in the low back and travels through the buttock and down the large sciatic nerve in the back of the leg. You most likely have a pinched nerve. The reason I recognize that is because I am dealing with it in my left leg. More on this site:
