I have recently been prescribed Levlin for severe endometrosis and have been taking it for a week but feeling worse with pain and tenderness. Is there anyone out there that has had the same experience, do you feel worse before you feel better? I was on Zolidex in the past and felt worse before I felt better as the Zolidex was shrinking the endo but not sure why I'm feeling this way on Levlin. Can anyone shed some light??
