sore throat

Hi, my problem is chronic and repeats every month. 4 years ago I took Hepar sulphur 200C one by day for one month, Mercurius solub 30C 3 x day first 2 weeks, then 2 x day one week and then 1 x day one week, and Sulphur 30C 1 x week for one month. 2 years ago another homeopath tried several: Pyrogenium, Acconitum, Arundo Maur, Silicea,... My symptoms are: all begins with cold air and drinks, then I feel tickling my nose/uvula/pharynx. The day after I feel hot on my face, without sweating and feel very cold, I touch water and is very cold; 2-3 days after I start to sneeze, appear wound on my nose and I have a terrible headache on one side, normally at right; sometimes fever and finally, sometimes, my throat get infected. I made better with first treatment but now I need anything else and any homeopath have the key. I forgot important symptoms: at same time I feel palpitations, I can feel my heart; my normal blood pressure is min7-8/max12-13 (mm Hg) but when I start to feel all symptoms is min9/max12-13; I alternate diarrhoea with constipation and haemorrhoids (normally not bleeding)Can anybody help me?Thanks
