Varicose Veins

Sure some other GN’s will suffer with these pesky veins. Mine are mainly on my front calves and knees and are very small but lots of them and unsightly. They just seem to appear overnight. Round my ankle on right leg which gives me some pain. I’m 68 and want to have them treated as worried if I knock my leg they could ulcerate as skin seems quite thin on my calves. Know I’ll have to pay and found a reputable clinic and read all their reviews. I’m very active and do my 10k steps most days. Any advice?
