Looks like Herpes Infection. Right?

During last Nov 2020 , I experienced first some cold itchy sores on hands and later once on genitals. After some days , some cold sores appeared like Herpes above lips too. These above lips cold sores always appear right from my childhood whenever I have got fever. Cold sores on hands (palms and in between fingers) and genitals are the first time. In 2020 Jan month , I visited my maternal uncle home who were experiencing itches. I am believing maybe I got infected from there. So I contacted some online doctors in pharmeasy and medlife and they suggested 200mg * 5 times a day course for 10 days. After that itching and sores healed a lot. After that , I am taking 200mg dose one time a day every day to take the virus in control as suggested by online pharmeasy doctors. And it's in control. But if I stop this medication for 3-4 days , sores re appear mostly on hands. But I don't want to continue this medicine for life. It can have serious side effects right?
