 [ Symptoms ] my shin bones are very soft and can actually dent if i press my finger on them what gives  if i wear socks that are too tight i get more than just the standard ring that most people get if the socks are short and do not reach my calves i actually get dents in fact if i for example lean against a coffee table with my legs so that someone can pass by me in a crowded situation they dent i can even dent them as a novelty to show people just by pressing hard enough with my own finger you should also know that i have mixed connective tissue disease as that may be relevant [ Disease ] i know you believe the problem is sinus drainage but has anyone evaluated you for acid reflux i mention this because people especially those with sinus problems often believe they are constantly coughing up nasal drainage when actually they are coughing up stomach acid you can test this theory yourself by taking an over the counter antacid for a few days to see if it helps the problem a lot of people are not aware stomach acid can move all the way up the esophagus into the posterior portion of the mouth especially when sleeping sometimes acid reflux is actually diagnosed by a dentist who notices substantial erosion of the molars caused by stomach acid if the antacid helps or if you can correlate a pattern of phlegm with food intake you might take up the acid reflux idea with your health care provider during your next visit wishing you well
