Ok whole story. Was diagnosed with ankle sprain when I started having pain in front of ankle, but I didn't sprain it! It just started hurting so they put me I'm boot for 6 weeks all the while it kept getting worse. I had swelling, shooting pain, burning, color change, muscle spasms. You name it I had it. It also spread to my other leg. Went to different Dr who diagnosed me with CRPS. I took off boot that day and started to ice ot to get swelling down. It only took two days for 90% of swelling to go away. I couldn't walk on original foot after being in boot for 6 weeks. Started physical therapy and started walking after a week in a lot of pain. No one told me not to ice! I think that's what made it spread to other leg when I was in boot. I was taking it off and icing it. Just started taking meds when burning just stopped. Had a block but it didn't stop the tingling. So sorry couldn't say meds made it stop.
