My grandmother has, since 24 hours ago had pain in her right foot. She complains of pain when walking. Last night, about ten hours ago, she noticed redness on both sides of the foot, by the ankles. The pain is still there now (the morning after) and i think the redness has gotten bigger in size. I think there might be a slight bit of swelling but i can’t see that over her socks now that she put them on. Please write to me and tell me what this could be. I read about blood clots and am freaked out. She does have high blood pressure and varicose veins. Thank you.
