<human>: Hi recently when I stand up I sometimes experience lightheadedness and muffled hearing, also sometimes when lying on my tummy and lifting my head up (this one I have had on and off for years) I am 40 not overweight with normal blood pressure. I have also had a pain in my left side around the bottom of the ribcage front and back for a couple of weeks. Defo not kidneys, I can make it worse by bending my head towards my chest. I feel fine when being very active - just spent the weekend running around with v energetic nieces at adventure playground. Any ideas?!
<bot>: Hi thanks for using Chat Doctor. 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 Diclofenac 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 X-ray chest PA view to look for any problem in lungs. Hope I answered your question. Wish you good health. Regards Chat Doctor.
