My husband's right leg has been bothering him for the last month. At first we thought maybe nerve damage from a knee injury years ago. Now we are a bit worried that it may be a blood clot. Symptoms are: His right leg from the knee down, his calf hurts but the biggest symptom is numbness and coldness from his ankle down, his toes especially feel like ice. The coldness and numbness wakes him up from sleep. It does seem to help but only a little if he hangs his leg off the bed, but it is not going away. Also the more he is up on it the worse it gets. Please any advice would be appreciated.
