I have had severe insomnia for going on 5 day s now. No sleep at all! Yesterday might leg, ankles and feet began to swell. They are terrible as of tonight, ie: tripled in size, very painful, ankles look bruised, burning, aching and pitting. I am 49 yr old female. I also am experiencing pain all over my body & seem to be hallucinating. I wonder if my pain med could be causing this. Please help...getting scared and feeling quite crazed right now.
