Hi Rachel,
I am so sorry to meet you under this circumstance but you have come to the right place for support.
My RSD was from a horrific painful IV. When the doc infused the anesthetic, i had this sharp pain passing through. The scale of pain was beyond 10. I had the RSD in both hand and arms and feet and calves. Therefore, when blood was drawn or IV was placed. I just let them did in either one of my hands or arms but requested an experienced nurse to set the IV so that she would not poke me again and be gentle. So far, i did not seem to have a problem.
Please get help right the away and seek aggressive treatment as soon as possible.
Take care,
Numb
