During colds, I get coughing spells that are nonstop, to a point of breathlessness. At the point I don t feel I can catch the next breath an eletric shock starts in the center of my chest and runs thru my vessels into the shoulders and down both arms. Both arms drop with great weakness, almost paralized. The last time, I dropped to a cold tile floor (naked) and lay there until the stining pain eased off and my strength returned. Lasting aout 10 minutes, The attacks worsen with age. Now 50 DAV,SC with hoshimoto s. Sjogren s syndrome, Fibromyalgia, GERD,Tpye 2 diabetes, chroinc severe dression and mood swings. Living with most of these 25 years now and my only child (daughter) has most of the same since 9, now 28. Both of us nonsmokers. No drugs, rare alcohol intake. I think the shocks is related to the dry lungs caused by Sjogren s and increade fluids.
