Sinus infections have different causes and determining this cause may not be that easy but it is required for physician to prescribe right kind of antibiotic. If you have been given an antibiotic and your sinusitis has not responded to it, then you might have been given wrong antibiotic. You may choose to ask another doctor’s opinion or try another kind of treatment.

A danger in taking wrong antibiotic is developing resistance to this medicine. Antibiotic resistance has grown to be a major health threat making it very important to be accurately diagnosed by a competent doctor. It may sometimes be difficult for physicians to give best prescription for your condition so it would be best to give them all help they can get. You have much at stake and giving Doc all he needs to know will improve chances of you being given right antibiotic.

Powered wheelchairs have three different drive wheel types. The front-wheel drive chairs are built with large front drive wheels and casters in rear. The mid-wheel drive chairs have larger wheels on rear and casters on front. The rear-wheel drive chairs are designed in such a way that main drive wheel is centered under user’s center of mass. Others are called specially powered wheelchairs, such as stair climbing powered wheelchair that are designed for off-road use.

A powered wheelchair has base that contains motor, battery and wheels. The seating system is mounted on top of base. Wheelchair of this sort usually has four wheels and is controlled by input switches.

There are also wheelchairs that can be folded and are specially designed for use in traveling. Traveling with wheelchair requires a personal vehicle that is modified to contain wheelchair. These wheelchairs have batteries that are housed in separate boxes that are easy to remove.

If you are still not satisfied with power mobility that your powered wheelchair offers, there are other options available. There are add-on power systems which convert manual wheelchair frame into a power mobility device, and power-assist wheels that are considered transitional products between manual mobility and power mobility.
