I have severe pain in my right calf..especially when standing. I am diabetic and obese. My A! is 7.0 I take Gabapentin and that seems to help but it has gotten worse over the last few weeks. After sitting for a period of time, when I stand up my foot is numb. I just noticed tonight that the front of my right leg may be swollen. When I press in it stays in. should I get a dr. appointment?
