Left sided pain: The medications that you are taking can cause difficulty in thinking, speaking, and memory. It is important to review the proper dosages and timing of the medications with your prescribing physician to avoid an overdose. I am not sure what the cause of the left sided numbness, poor function, and spasms. This may be due to a previous stroke or a neck problem with spinal cord injury.
