Suggest Treatment For Leg Cramps And Hives

For the last six months or so I have had problems with itchy palms in the morning only. Could be one had or both. I then developed leg cramps at night and began breaking out in hives at night and waking up with them in the morning. I never have hives during the day. I have occasional mild nausea and now have developed TMJ. I'm just trying to determine if these symptoms are stress-related, perimenopause related (I'm a 48 year old female) or if something else could be causing these symptoms.
