Cramp in calf and up back and side of thigh,in 1 leg,sometimes 2. had 5 neg ddimers,1 last night, ultrasound4 weeks ago,all clear. have i got dvt?

No, no, no, no, no,!: You do not have DVT! One negative d-dimer rules it out. Five is crazy! US is just frosting on the cake and not necessary. You have a leg cramp. That's all! Leg cramps are common and they hurt. Try stretching exercises to tone your leg muscles (try walking on tip-toes for 5 minutes twice a day) and when you lie down, keep your toes pointed up toward your nose, not down toward the bottom of the bed
