I am not sure from your description if either the front or back has dropped down, or whether both have, but another cause could be that the VTA (vertical tracking angle) has shifted. It could be that the VTA adjustment, if there is one, could have slipped, letting the back of the cartridge down. Also, regarding the tracking force, some tonearms have a graduated VTF (vertical tracking force) scale on the counterweight on the opposite end of your tonearm. If you can adjust it, you might try reducing the VTF slightly to see how it affects cartridge height and how LP's are tracked. Is the needle now skipping and has the sound changed since you noticed the changes in cartridge height?
needle problem
Suddenly, the angle that the needle hits the record has decreased, and thus the cartridge sits lower in respects to the distance between it and the record, so that if the record is even slightly warped, the two collide.
Any ideas on what could be wrong and who could fix it?
