Hello! Welcome on HCM! Regarding your concern, I would explain that your symptoms seem to be related to a musculo-skeletal pain. The headaches don t seem to be related to the shoulder pain. Anyway, I would recommend consulting with your attending doctor for a careful physical check up and some tests: - complete blood count - PCR, sedimentation rate for inflammation - a sinus X ray study - a sinus discharge bacterial culture (if you have nose discharge during this period) - a cervical spine X ray study to examine for possible chronic degenerations of the cervical column that may lead to irradiating shoulder pain. Meanwhile, I recommend taking ibuprofen for the pain and performing some light physical activity for the shoulder pain (it will help relieve muscular spasms). Hope to have been helpful! Greetings, Dr. Aida
