Swelling in both feets bottom. Guidance.

Hi. I had digestion problem so I used to sit longer in toilet and stress my bottom feet a lot. As days went by my feet bottom would become numb while in toilet but had to complete process so kept sitting and stress on feet bottom continued. But numbness would go away in 5-10 minutes and then I will go on with my day and was able to walk. But as days went by my bottom feet- metatarsal and heel area started paining. But I thought it would recover as I stopped stressing feets in toilet. But as days went by and I kept walking, My feet metatarsal area and feel started paining and needle like sensations started coming at night. Then both feet bottom got swollen and now when I stand and put weight on feet or walk, it pains and swollen bottom feet and fingers become reddish in colour and start paining more. I tried cold pack and hot water with salt but swelling there. I want to be able to walk again and live my life. Seems small problem but it did not heal after rest so now need your guidance.
