For all that have tightness , there is a test you may do to check it out. Take a warm to hot fluid to expand the band. It will allow you to get things down,, if you still have pain after that,, then see the Doc asap,, at 4 months,, you shouldnt be over 1.75 to 2 cc inserted
Amber, yes, the band is too tightly adjusted, you should be able to swallow fluids without any sharp pain. I've had Mine now for over 1 year,, the first test they do after the adjustment is supposed to be a drink test. So yes,, get in touch with your Dr asap
