Hi I have some neck/back disc problems and am having physio which is helping I am taking just two ibuprofen an two codeine at night. But I have developed the following symptoms. Dizzy clumsy lump in throat pins an needles feeling and when I go to bed I have the muscle jerking thing which I think is quite common as I fall asleep but it carries on all night along with hearing loud noises I actually though the alarm had gone off but it was still night and seeing flashing lights as I drop off also just as I drift off its as if my brain changes my thoughts an wakes me also blurred vision and really really vivid dreams am feeling so crap almost scared to sleep have convinced myself I have some terrible disease like cjd do I need to go back to docs.
