I Have Had Gradual Pain In My Left Arm And

I have had gradual pain in my left arm and have had difficulty squeezing or opening objects that require strength. It feels weak. Also I have had a head ache and eye muscle spasms form about 5 days now. Today I have had a dull headache and slight dizziness. The weird thing is that I just got off the phone with my daughter and she is sick in Arkansas with many of the same symptoms. We did spend the holidays together...in fact she just headed back to Arkansas this weekend. She had to call in sick today with a sore throats and coughing. I haven't exhibited those symptoms yet but I still feel a little odd. My husband has felt a bit odd too today with headache and slight dizziness. We were all exposed to my brothers family in Oklahoma this past Friday and my brother stayed at his home sick with some kind of flu-like bug.
