Feeling head rotation, cramps in chest.

Feeling head rotation and mild cramps (like needle) in left side in chest very mild. I had high blood pressure and taking medication (Tazloc-AM) from 3-4 years. Recently I noticed head rotation and felling that I'm felling down. And very mild cramps on left side in chest. I was tested with BP 150/100, and ECG was normal. I have been suggested to use BP tablet regularly and E-Cod plus tablet. But still I'm feeling that my head rotation for 1 or 2 seconds and feeling tensed without reason. After 10 days I took BP test and it is normal now 130/90 and ECG also normal. I have been suggested with gastric medicine along with E-Cod plus, and calcium tablets. With this tension I started reduce my food, and feeling light. But still sometimes I'm feeling very mild head rotation and very light cramps in chest for few seconds. Is this my psychological feeling or do I have any problem in heart or brain. Actually I'm feeling tensed and even afraid to take bath, as I'm feeling that I may fell down
