I have been diagnosed with high blood pressure and under medication for the past 20 years. Currently I take 20mg of telmisartan twice a day. Since last 2 years, I'm also suffering from frequent coughing, chest congestion and wheezing. Since last 2 months, there seems to be a sudden onset of all these issues once in every few days. First, It starts as dizziness, then I feel like fainting, heavy feeling in chest area, shoulders hurt, after 5 to 10 mins of this suffering, I either belch or yearn continuously for a minute or two. Feel better for few mins, again the whole process starts from beginning (dizziness, belching, etc). BP measures around 150 to 160 during these episodes. Sometimes this goes on for 30 mins and sometimes it's for 2 hours. Suffering a lot. Any help appreciated.
