I had it when I first started switching from lexapro to cymbalta. I also had an amazing headache that I thought was from the vertigo. It ended up being a sinus infection (we think) but I had no other symptoms of a sinus infection, including when they did a visual check. They treated with antibiotics, but it didn't work so they treated with stronger antibiotics.
After a little while it just went away. Antibiotics or time, it's gone- and that's all I care about.
When you cannot stand, on whom do you lean?
