Urinary Tract Infections. Urinary tract infection is common in patients and a urinalysis should be performed with any symptom flare-ups, any fever, or any change in bladder symptoms. Treatment uses appropriate antibiotic regimens. Some evidence suggests that cranberry juice may help prevent infections. [See In-Depth Report #36: Urinary tract infection.]
Bowel Dysfunction
In addition to maintaining a high-fiber diet and drinking plenty of fluids, bulk fiber such as psyllium (Metamucil), with or without a stool softener, may be needed. Going to the bathroom the same time every day, particularly after a meal and waiting there for a movement, reduces the risk of losing control later in the day. Exercise helps patients avoid becoming dependent on laxatives, enemas, or colonic irrigation, which can eventually slow down the bowel and cause imbalances in electrolytes. Biofeedback techniques may be helpful in some patients with limited multiple sclerosis.
Tremors
Major tremors can be very distressing and are particularly hard to treat. Carbamazepine and glutethimide have some possible benefits, but in general drug therapy has been disappointing. Weight applied to the affected limb has been beneficial in about 20% of cases. Surgery is very controversial.
Facial Pain
Trigeminal neuralgia is severe facial pain, usually on one side, that can be very severe and may be triggered by an event as mild as a breeze or teeth brushing. If nonprescription painkillers fail to alleviate facial pain, it can be treated with anticonvulsive medications. Carbamazepine (Tegretol) is currently the drug of choice. Carbamazepine is also effective on other types of MS pain and spasm-related symptoms, including itching and aching. Another antiseizure drug, gabapentin (Neurontin), however, may be particularly effective for MS. This drug also appears to improve blurred vision associated with MS and may help spasticity in general.
Other drugs used for this symptom include phenytoin (Dilantin), diazepam (Valium), or pimozide (Orap), and the antidepressant amitriptyline (Elavil). If severe pain persists and interferes with function, some patients elect to have a section of a nerve surgically removed or blocked. This relieves pain but causes numbness. Before patients commit to such a procedure, they should ask the doctor to temporarily block the nerve with an anesthetic in order to experience the effect of numbness before undergoing irreversible surgery.
