Trying to find source of problem with swollen lips, tingling, daily for past 6 weeks or so. Some days worse than others. Apparently a systemic cause, not external sensitivity (lipstick etc.) as far as I can tell. Haven't changed any "products" i use in this time. Was put on Fosamax for seven weeks, but Doc dropped that three weeks ago in case it was the cause. No change in lips. Wonder if my long time Levothyroxine is somehow the cause as COSTCO pharmacy did say the providers can change with meds due to their cost... Label says only Levothyroxine 100mcg.
