Hey found a pea size lump on my right labia majora about a week ago. Since then it's starting to grow in size nearly to a grape becoming very painful to walk. Not a ingrown hair as I hadn't shaved in 8 weeks or longer (to much information sorry) I'm 29 recently switched to carezette pill (pop) having side effects from sickness to migraine attacks once a week.

Would this be another side effect of it? Or could it be cancerous? Haven't rang gp yet will on Monday tho
