Hello Tanks for writing to H.C.M. for your query. I have gone through your query regarding cold , cough, and pain on back of chest specially on coughing, turning and even touching. Your symptoms are indicating that you are suffering from acute respiratory tract infection ? with pneumonitis. Other possibilties of chest pain may be dry plurisy or myalgia. To frame the diagnosis you are advice for these basic investigations- (a) X-Ray chest (P.A.View). (b) Culture and sensitivity of throat swab. (c)Blood- CBC, ESR, blood sugar (F. & P.P.) (d) Urine - Routine & Microscopic. After a thorough examination and co-relating the investigation s reports one can reach to correct diagnosis which may later on plan for treatment. Regards.
