I had a really bad cellulitis infection on the inside of my thigh and blisters on my knees and randomly down my legs. I got an iv antibiotic at the hospital and another antibiotic to take home. I was told 4 times a day for 7 days. I've finished my antibiotics and all of the redness and blisters are gone and my skin is healed however I still have a large lump under the skin on the inside of my thigh. Is it normal for that to take longer to go away or should I go back to the hospital?

The er doctor gave me 1gm of vancomycin bur i had a mild allergic reaction to it. Then they gave me 3.375gm of piperacillin-tazobactam, all through iv. I was told if i had waited another day i would have been admited ao rhey could cut and drain my leg. I was prescribed 300mg capaules of clindamycin, 4 times a day every 6 houra for 7 days. Ive finished the antibiotics,about two days ago now, but there is a large hard lump left under the skin with very minimal redness. It gets a little itchy under my clothes and the only pain i feel is if i poke it a little roughly .

Brief Answer:
Healing normally with its natural sequel

Detailed Answer:
Dear young lady,

Welcome back and thanks a lot for your so swift follow up with pictures.

After reviewing all the three pictures let me reassure you totally that the area is healing normally with its natural sequel and there is no abnormality in the same. Therefore at present there is no need to rush to hospital.

To tell you simply- the healing of tissues forms a swelling which is know as "granulaoma" formation. This is much required and natural process which is perceived as swelling from the superficial appearance of skin.

As your cellulitis must had been deep so its just taking bit longer of the time to heal. I also suggest you to not to to unnecessarily touch, pinch or pop the area as can get inflamed.

The minimal pain and mild itching are good indicators of healing. So rest assured and relax.

I hope these information's will relax you completely. If you have further queries I will be happy to help or if not then can close the query and rate the answer.

For any future guidance regarding skin or related conditions you can ask me directly at:

"Wish you good health"
