Left arm and shoulder pain symptoms and conditions

I have a seve4e bronchial infection and was prescribed Levaquin 750 mg once a day for 5 days. Tomorrow will be my fifth day although I will not be taking it. When I started the medication I was beginning to feel better although I still had a really bad cough. I was also put on an inhaler.
I woke up today and felt like I have been hit with a truck. I can't hold anything in my hands, my kneew and ankles feel like someone took a bat to them and I have spent all day trying to figure out why I felt worse overall and now why I was feeling this horrible pain that is practially crimpling me.
I found this site when I googled "sever bronchial infection and joint pain".
I'm calling my dr tomorrow but I'm scared. Will this be permanent. I already have 2 herniated discs in my back and now I can't even walk or get up from a seated position.
I have a 1 year old I cannot even hold and have ot have someone help me take care of.
I hope this goes away and soon. The pain is close to unbearable.
