Patient discussion about dose

Q. dose it ever get better? Dose the feeling of useing ever go away?

A. Well to answer you question bluntly, no they never go away. It just gets easier to say no. I still want to use everyday and I have been clean for 4 years. I still have using dreams. The hard days are when you try to tell yourself that all your problems would go away if you could just get high one more time. what one more time gonna hurt?.....Everything....drugs are way to escape or make you feel like someone your not. my biggest hurdle was really looking at myself and then forgiving myself for all the pain my addiction caused. Everyone has their bottom. Everytime you want to use, put yourself back at that bottom. you will come to realize that life has been patiently waiting for you. The darkness will will fade and you will find your place. Good luck to you I hope you find strength will come in time.

Q. how long dose costochondritis last

A. a friend of mine who had the disease saw an improvement within a few weeks, and it resolved completely within a few months,but his doctor said there are patients in whom this problem persists for some time. All symptoms of pain should resolve within six months.

Q. hemorroid stapling dose any one know about this first hand,or had it done themself? mail me if you have!Thanks Hi, I will have this done on 8/4 . I do need to have some info. about it from someone who has had it done what I need to know before hand!HOW MUCH PAIN, BLEEDING ect. Drs can only tell you so much because they do the surgery but not had it done themself. Please let me know soon, Please!

A. I haven't had it done first hand but I do know from people who have done it that it can hurt in the first few days after and there will be slight bleeding, however that is expected decrease dramatically and make the bleeding eventually stop.
