am experiencing severe leg and foot pain. My blood n pressure is 151 over 85. I hit my leg on a hard object which caused a golf ball size knot below the knee. My leg is red and swollen and somewhat hot to the touch. I am also out of my hydrochlorothiazide medication. I have not had it for the past few days. The pain is keeping me awake and unable to sleep. Can I wait till morning to address the issue with my doctor?
