Tingly, numbness and swollen feeling in leg and foot. doesn't look, but feels swollen. could this be a blood clot due to wearing skinny jeans?

I don't think : Skinny jeans can cause a blood clot...I'm not saying you don't have a blood clot, but find it hard that they could cause one....Are you a smoker?On birth control pills? Those are things that can potentiate a clot...

I doubt it: Diabetic peripheral neuropathy can often cause symptoms like this (other causes of peripheral neuropathy too). Need to get the lumbar spine checked out too, though this is less likely. I'm not sure how tight the skinny jeans are, but this cause of tinging is greatly unlikely. Skinny jeans are known to cause meralgia paresthetica (google it), though this is far from what you're describing.
