Patient discussion about efferent

Q. Where do you go for health information? Where do you go to get health advice besides here on imedix?

A. googeling can be very helpful but you may encounter hundreds of unreliable web sites that who knows who opened them. so i use the link above and i really like websites of big organizations ("national association of neurosurgeons" type of thing..), this website, wrongdiagnosis.com is also very good...there are quite a few...

Q. will it ever go??? I have acne on my face for several months, and although I went to see a dermatologist and treat it, I still have these ugly pimples and zits on my face. I feel really ugly and sometimes I don't want to go to school, and just want to stat at my room not let anyone see me. Will it ever go away? What should I do?

A. Acne usually abates and disappears with time, but the chances for that depends on the specific type and features of the disease. If you still suffer from lesions despite treatment, you should consult your dermatologist and seek further help.

Q. Should I go for the knife? I have essential tremor for many years, and in the last few years it seems nothing helps it, and although I tried all the drugs my doctor could offer me, nothing helps. It really ruins my life, and recently I read about a surgery that suppose to treat it, called thalamotomy- does anyone know anything about it?

A. It's a possibility, and considered effective (reducing tremor in most of the patients). However, it has quite serious side effects, that can result even in weakness of some parts of your body. You should think really good before you opt for this treatment. Good luck!
