:''( Monday, at work, my back was really bothering me. I got home later that day and started having what felt like cramps in my knee. As the evening progressed it got so bad I ended up in the ER. They put me through every test, ultrasound for a clot, etc... only abnormality was my TSH was elevated from a 1.8 up to almost six in less than a month. Last night and all day yesterday, every 20 minutes it feels like someone is taking a hot drill through my knee. It does not radiate from my back. Is this sciatica? I have not slept for more than 4 hours in the last two days. No pain pills work, nothing. Valium, Percocet, ibuprofen, tried them all - nothing. If this is sciatica, I am going to get my surgery moved up IMMEDIATELY if I can. Can someone please, please help me and tell me if this is what that feels like? :''( I am at my wits end and don't know what to do.
