Sorry to hear you are feeling down Bambi! *hugs* I know all too well how depressing it is to be in such pain, and to lose faith in the new things you are trying. The Dr said 4 weeks? I personally would give it another week, and then call if you are still not feeling much better. (again, just my personal opinion) I don't have a skin tag, so I'm not sure how that feels, but maybe that is what is causing you the most pain right now. I know others have mentioned how irritated and sore those buggers can be! :(
I hope your being busy for the next couple of weeks can help offer some distraction, and that you'll start to notice a difference soon! I have not yet had Botox, that's the next step for me, so I can't say from personal experience what to expect, or when you should start feeling better, but hang in there. *hugs hugs, and more hugs* I feel your pain, and know how awful this all is, but I just keep focusing on all the great things in my life, and most days that's enough to help cheer me up! We are all here for you!! *hugs again*
