Swollen bulgy Varicose veins in one leg.

I have few bulgy varicose veins on my right leg. I have swollen bulgy things on my calf and behind the knee. I have around 12-13 small bulgy lumps like varicose veins. I had leg Doppler scan and it didn't show any Dvt. Dr said I have varicose veins and have to do treatment for that. I have knee pain on the same side. Knee pain for more than 4+ years. I am doing physical therapy for that. They are doing massage therapy for knee. During the therapy, the therapist massaged my knees on all the sides with so much pressure. She pressed my varicose veins so much during the therapy. I have one big bulgy varicose on that same spot. It was so painful where they pressed that bulgy varicose veins. I just screamed and said I have a big varicose. After that, it started to hurt more where he pressed and still hurting. Is it ok if we press the bulgy lump varicose veins?
