When i sit in my truck for about 30 mims my right thy starts to hurt like a chairle house?

Nerve or vascular: You are either getting a "pinching" of your nerve causing these symptoms, or you have some vascular issues that get affected when in the siting position, causing a possible decreased blood flow resulting in your symptoms. Most likely a nerve issue, but see your dr. For an evaluation and some testing to get properly diagnosed and treated, best wishes.
