Leg cramps and dvt. Please help!

Calf cramp since tuesday. Please help!?
So I took a two hour plane ride and a two hour car ride with breaks in between each trip to walk around. Later in the day Tuesday I started freaking myself out about blood clots. I have a weird phobia of them. Well my calf has been crampy. Its not anything terrible and I did go walking form two miles yesterday. I figured if I had a clot I wouldn't have been able to walk two miles. And the pain hasn't gotten any worse and no new symptoms.

Oh and I've had several negative ultrasounds in the past as well as negative d dimers, my last negative ultrasound was two weeks ago

I don't think you have anything to worry about! your d dimers are negative, you stoped and walked around when on your trip. If you had blood clots in your leg your leg would be swollen.

Ice the sore calf. This is considered the most effective method for pain relief with sore muscles. Ice the area for about 15 minutes four times a day until the swelling and pain subside. Avoid direct skin contact by wrapping the ice pack in a small towel. Keep your leg elevated whenever possible and start icing within 24 hours.
Take an over-the-counter pain and fever reducer. Ibuprofen, aspirin, and acetaminophen are all effective pain relievers. Make sure to eat something before taking these pills. Wait 24 hours to start taking pain relievers.
Wear a compression to reduce swelling. Compression bandages are available at most pharmacies. Wrap for support but do not tighten the bandage to the point where circulation is compromised.
Use a heating pad if you are still experiencing pain after four or five days. Use heat when you return to physical activity, especially before stretching and exercising.
Stretch your calf muscles before attempting any strenuous physical activity, such as running. Stretch often throughout the day to avoid cramping and subsequent pain.
