Pins and needles left thigh after Tummy Tuck - Is this due to surgery or because of all the changes in habit

Good morning. I had a mini tummy tuck 6 weeks ago, followed by large hematoma that needed to be drained, scar is healing well but have been laying down for 4 weeks and I am usually a runner so try to keep fit. Since the op I’ve been experiencing pins and needles in the left thigh with a little bit of numbness, and also at times in my hands. Is this due to surgery or because of all the changes in habit like laying down, laying on back, no exercise? Just wanted a second opinion please.
