If the area of the big toe is swollen and painful when touched, it is possible that there is a localized disease such as nail infection or gout. This is something that needs to be initially determined by a doctor in conjunction with a physical examination. If the redness, swelling, pain and gout are caused by nail fungus, which is a local inflammation, then you can choose anti-inflammatory drugs such as cephalexin. The other thing is that the local nail needs to be trimmed. In the case of severe nail infection, some of the nails should be removed. If gout is considered to be the cause, you can improve the uric acid test, and if the uric acid is obviously high, then it supports gout, and you can choose drugs such as colchicine to lower the uric acid; in addition, you should control your diet, and try not to drink beer, eat seafood, animal offal and soy products; avoid walking for the time being, and you can take oral painkillers such as Fenbid for pain relief if the local pain is obvious.
