Hi, I Started Having A Slight Itching In One Part

Hi, I started having a slight itching in one part of my palm. After a few days, the area in my sole[leg] between the fingers started itching. I consulted a doctor who suggested me to take teczine for 10 days and Dazit for 30 days. I took the course and had no symptoms for 30 days. But 30 days after having all those tablets , I again had the same problem with my scalp, abdomen and other parts of the body itching. I sometimes get a round rash and at other times just a red itchy skin. I have taken all the tablets, I wanted to check if this is the right course of treatment or if I need to get any other tests done to find the root cause of this? From my understanding, Teczine just seems to be controlling the symptoms [itching] but nothing else. Please also let me know if taking Teczine 5mg for such long duration 30-45 days is a good idea or if it will cause any side effects.Now my blood pressure got increased to 98/140. I am a Male - 27 years - living in Banaglore....I am not taking any other medication that could have started this itching. Thanks Hari
