Ring worm infection

I am having ring worm infection on my skin since 5 years ago. I was infected by a cat that used to have until 3 years ago. The symptoms appear frequently basic on my hands, legs and waste and I use lamisil cream. The problem is that I can not get rid of them as when the symptoms diappear after 2 or 3 months they appear again. I tried the oral medication using lamisil tabs but there I was not heal 100%.

Hi,
Topical antifungal drugs containing miconazole (Daktarin, Micatin & Monistat), clotrimazole (Canesten, Hydrozole), terbinafine (Lamisil), butenafine and tolnaftate (Tinactin), many available without a prescription, are used to clear up the infection.
Griseofulvin is a traditional drug used to treat ringworm in both animals and people.
Fungi thrive in warm, moist areas, such as locker rooms and swimming pools, and in skin folds. The fungi may be present without any symptoms.
To prevent ringworm:
Do not share clothing, sports equipment, towels, or sheets. If you think you have been exposed to ringworm, wash your clothes in hot water with fungus-killing (fungicidal) soap.
Avoid walking barefoot, wear appropriate protective shoes to the beach and wear flip-flops in locker rooms.
Ringworms can spawn more than once in a outbreak whenever skin come in contact to moister only if you have came in to contact with ringworms once in a life and the needed vaccine may be applyed once more every 2 years to prevent you from having a outbreak.
