In reply to Chapel John.J:
Taking Ibrouprofen is safe in the short term, so long as you dont have asthma.
Ibrouprofen is one of a group of drugs called non-steroidal anti inflammatories, which are well used in the treatment of joint pain. The main associated problem with long term dosage is stomach ulcers, (this is lesened if you take them with food.)
always take according to the instructions on the packet, never more there is often a misconception because its over the counter its safe. However if is safe to take paracetamol with ibrouprofen as they are from a different group of drugs, but again stick to the recomended dosage.
make an appointment with your doctor as soon as possible, however i know this can be a pain! so i n the meantine i would suggest you go to the chemist and ask to speak to the pharmacist(not the girl on the checkout!). they are extensively trained, explain the situation and when your appointment is. they will be able to suggest the best thing to take in the meantime, this way it will be safe prompt and is more likely to be effective!
good luck joint pain is awful!
