those are not signs of DVT.
sitting down would take pressure off of your hip joint and ease pain for arthritis or tendonitis or bursitis.
it doesn't sound like you have a DVT.
you can try to ice your hip and do more stretching exercises
also you can try over the counter anti-inflammatories such as ibuprofen or naproxen sodium to help decrease inflammation in your hip and see if those help
