From my experience of doctors, they never seem to be agreed on anything, but I had severe back pain for many years, and started taking ibuprofen, and it did help, but as my blood pressure was 105/180, my octor advised me not to take them as ( He said ) " they narrow the blood vessels". So I don't take them.
You are all probably right, they are safe if there is no evidence to prove otherwise, but I can't take a chance just in case, but if you are in good health, then no worries. I must just add, that after all the years of pain, and being unable to stand straight without severe pain, having to roll out of bed and climb up slowly to standing position etc i was given acupuncture. 3 times over about two weeks, and pain totally went, first time for 30 years i could move in any direction without gasping with pain.
