<s>[INST] I have a sensation of pressure in the upper pec area on the right side just below the collar bone. Along with it, I have soreness through my right lats as well as a great deal of sinus congestion. THere is not any pain just discomfort and soreness. I have not worked out in nearly a wekk due to travels so it seems out of line to think this is fitness related. Any thoughts? [/INST] Hi. I would suggest a X-ray of the neck to look for a cervical rib which causes heaviness and pain in that area plus numbness and pain in arm or forearm or hand. U should consult thoracic surgeon for it. For sinus fullness I would suggest an antihistamine such as basting or cetirizine. Steam inhalation with application of some balm or picks over the nose. You can have anti histamines on prescription. Thanks </s>
