Always go with your gut instinct, people are often right that there is something amiss. Trying to break this all down on your own can actually just make it worse. Your dad does need to be physically assessed which is why I suggested calling 111 if your concern is high or seen clinically by the GP (which is dependent on your GP). Sometimes you do have to persist, and pain is worthy of medical attention even if all that can be offered in the end is pain relief (if the cause can't be fixed, at least pain can be taken away)
Drug reactions are often misunderstood and there are different types of adverse drug reaction (ADR's). Sometimes side effects will be tolerated if a drug also has the desired effect, but stopped if the side effects (not drug reactions) are greater than the benefit. From my own experience with my mum I can say that it can be very difficult to know what is causing which symptom or sign and dementia makes it all more complex. Its hard for people with dementia to express their physical problems as they enter the later stages, if at all. So getting things checked out is likely the best option, even though you may have to press matters to get your dad seen -I personally would push for a proper assessment and suffer the embarresment if there was nothing seriously wrong in the end, rather than leave matters in the air and be sorry later down the line.
I hope you find a remedy to this soon for your dad and to put your own mind at rest -best wishes
