Thank you for the information. I am sorry to hear about your symptoms. Based on your description, you seem to have pain, swelling, redness, difficulty in walking, tight skin, and hot to touch in ankle and foot. This is not normal at all and must be investigated as soon as possible to rule blood clots as they can present like this. Some other possibilities would be cellulitis, arthritis, venous insufficiency but still doctor visit is must at this time and should not be ignored at all. Thus, please consider doctor visit now or go to ER.
Please let me know if you have any other question for me.
