Pinching soreness in inner thigh, deep vein thrombosis?

I've been through a bit of trauma recently, my father just died a few days ago, so I probably am a little too conscious of death right now. My problem is that the night after my father died, I began experiencing bad soreness in my inner thigh which later spread to the back of my calf. It hurt to the point where I limped for a day and a half. Yesterday, the pain was virtually gone, but today, the pain has returned (only in my inner thigh though, I believe I accidentally hit that area causing it to hurt again). I have also developed a slight cough, but this could be from anything.

The reason I am paranoid is because I'm terrified of it being deep vein thrombosis . I have been panicking to no end over this because I cannot afford a doctor to check with.

I am only 20 years old, I've never had surgery, I've never taken birth control pills, I'm not overweight. I have, however, been sitting for a long period, though not excessively long. Please tell me I am overreacting.

I've actually had a pulmonary embolism and when told my doctor I didn't have any pain in my legs, he said that it kills you so fast, you never know you have it. Go see a doctor if it feels like you have shortness of breath and a sense of impending doom, it can feel like a heart attack, if the vein is thrombosed then it may feel hot and look red. Do what you need to set your mind at ease. You can afford a doctor more easily than a nervous breakdown.

You could have a pinched nerve in your low back causing this pain. You do need to have it checked out. Your doctor should take payments if you can't pay your visit in full or go to your hospital.
