Hello. I believe that it could be pressure on a nerve. I have tingle foot.
(it only happens in one foot). I had major problems with the sciatic nerve due to disc pressure in lower spine. The pain extended down the leg to the foot. The pain was very intense. I had 2 back surgeries. The loss of feeling in my calve and partially the foot, (with tingling), was caused by nerve damage the doctors said.
Nerve troubles can extend and skip places along the way! It's kind of weird to think that something at a distance can affect another area, such as the possibilty of nerve pressure around the disks in the lower spine may be affecting your foot.
I'm sure that there are several other reasons for the tingling sensations,
raynauds? Hope this helps, or others post their experiences to help you.
