Delayed tingling sensation from lip fillers, should I be concerned? (Photos)

It has been three months post (1.2 mill versa) lip injections. I'm experiencing intermittent swelling and tingling/numb sensation with some slight discoloration. it comes and goes at random. I dissolved some of it and it helped slightly. Any thoughts? An I allergic to this brands perhaps or am I not a candidate for fillers? My injectioner had no theories and is a little frustrated with me that this is happening.
