Hi
Welcome to the MedHelp forum!
A lump that increases and decreases in size ca be a cyst or an abscess. It is difficult to diagnose on net. Please take your mother to a doctor. Take care!
Please have your mom check in with a doctor. It may be nothing, but why wait?
Take care!
I'm sorry about your Mom too but I think Katrina81 is right - you probably posted on the wrong forum. Check on the health forums and there's a "ask the doctor" section so that might help you more. But most importantly have her see a Dr. as soon as she can so you both can find out what's going on with her. I wish you the best! :) p.s. and you are such a sweetheart coming here to find help for your Mom. she is very lucky to have a son like you!! :)
Um? Did you maybe post in the wrong forum? I hope mom feels better though
