Dr. Hanif warmly Welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. As for as his Blood Pressure fluctuations are concerned, it was due to angina and it s nice that he is taking medications for that. There are also chances of some kind of infection in heart muscles ot valves of heart. His cardiologist may rule out this suspicion. Rest of the problems are due to cold and flu. If he has chest infection ( Sputum with cough or otherwise, fever as he already has, runny nose, itchy eyes) I would suggest to consult his physician to add some antibiotics for him. If I was his treating physician I would have prescribed you Azithromycin antibiotic class of drug, if not allergic to. Paracetamol and Claritin are good. Keep giving him that. Give him water adequate enough to keep him hydrated properly. Avoidance of excessive physical activity is necessary. With proper rest and follow-up he will be alright. Hope I answered all of your health concerns . If you have further questions in future, feel free to contact me anytime. In the start of your question write my name, and I will get back to you in no time. If satisfied, please click you found it helpful. Have a wonderful time ahead. Best Regards! DR. MUHAMMAD M.
