It appears in your photo that the molar has tipped. You should keep wearing your current aligner and call your doctor to discuss this issue before you move forward or backward with aligners to prevent any future fitting problems.
I would call your doctor and ask him/her to examine you to make sure you are not having an allergic reaction. It is very rare that people do have problems with their aligners. Hopefully you are better now.
Since you already have an appointment for a consultation, you could wait and see what that doctor has to say about your different treatment options. Ofcourse you can also book a 2nd opinion appointment with another doctor, but you may want to wait until after you see the first doctor to gather more information before booking another appointment.
It is not uncommon to wear passive aligners on the top or bottom teeth at the beginning or end of treatment. Also, depending on the amount of movement programmed into the aligners, some people can wear them anywhere from 7-14 days per set and achieve the desired results.
