Hi,
The swelling from your going to your right upper thigh about 4 bigger than left following the slip you had in the shower, it might be due to trauma from the hit.
Good news that no blood clot is there. However, should observe for any unusual symptoms. Keep your leg raised.
Apply
cold compresses locally; if more than 72 hours from slip, should apply alternating warm and cold compresses.
I think the problem is within the lymphatic
drainage, so discuss with your doctor and angiologist to check them out.
With regards to this Anoro inhaler, I should know first the diagnosis it was prescribed. That would explain the other symptoms too.
Please write me back and describe in details regarding the respiratory problems you are having.
Discuss with your primary physician to set an appointment with angiologist.
Hope I have answered your query. Let me know if I can assist you further.
