I am scheduled to have orthopaedic surgery on my shoulder Thursday morning. I woke up today with swollen sinuses, a mildly sore throat, a congested nose and I feel like my glands in my throat are beginning to feel sensitive. I am not coughing & rarely in my history does a cold of allergies (not sure what I m suffering from) has it gone into my lungs. Is it safe to proceed or should I postpone? I am 62 years old, weigh 149. I have had 2 arthroscopic knee surgeries and a tonsillectomy. I am in decent health. Do have osteoporosus, psoriasis and high cholesterol. Not using any internal medications.
