Hi thanks for using HCM.
Your history suggest that you may have postural hypotension
.Get checked for BP at lying and then standing for 30 s to 1 min from lying position. The pain at left side and back may be due to musculoskeletal pain
. Take Tab Aceclofenac
with Muscle relaxant(Chlorzoxazone
) combination three times a day for 2 days. This will relive your pain. If not cured consult a doctor and take one xray chest PA view to look for any problem in lungs. Hope I answered your question.
Wish you good health.
