hi,
thank-you for providing the brief history of you.
Now as the
numbness hasn't gone for a long and all started by use of leggings, it can be due to two factors for which am assessment is needed.
the first can be compression of vasuclar system as due to which to which the blood supply gets restricted and the numbness occurs. But since you didn't mention of swelling this could be a less possibility.
The second factor could be a strain in muscles which must have lead to
nerve pinch and the symptoms arise. and you do have mentioned about numbness which is gradually increased and not gone since 3 weeks.
Post thorough neuromuscular assessment the exercises will be implemented to release the
muscle strain and improve the strength in the muscles.
Also, trying the McKenzie maneuver which you can find on net give you release of numbness symptom that it will be related to spine. As post use of leggings the muscle do not have a freedom of movement and can lead to spine problems. Which is common injuries we find in our clinical experience now a days.
As exercise can help regain the strength and flexibility later stages you may not face similar problems.
