Hi letsembellish, welcome and thanks for your question. Fosamax, as others, have side effects. Here's list of them from our site (HealthSquare) and from Merck the manufacturer (on pages 17-19).
Neither of these two problems are mentioned, so it would be interesting to know where you heard this, and if this is something new that we aren't aware of. I can't say wether or not these two things would happen, but I haven't heard it either.
If you are considering this med make sure you discuss all the ramifications of taking it with your Dr. so you'll be completely informed before making a decision. The patient is the only one who can decide what is best for them so do some reading on this so you'll know what to choose.
Good Luck...
